Typedef Documentation

◆ SharedMeshPtr

typedef MaxSDK::Graphics::RefPtr<SharedMesh> SharedMeshPtr

About SharedMeshPtr defined below : This template class act similar to CComPtr.

Using RefPtr<RefObjectType> will be much safer than RefObjectType* since this template class handles the AddRef and Release in its constructor and destructor.

Usage Example: class DerivedRefObject : public ARefObject { public: void foo(); };

Use DerivedRefObject without RefPtr: { DerivedRefObject* pObject = new DerivedRefObject; pObject->AddRef(); // Add reference pObject->foo(); pObject->Release(); // release the object pObject = NULL; }

Use DerivedRefObject with RefPtr: { RefPtr<DerivedRefObject> pObject = new DerivedRefObject; pObject->foo(); don't need to worry about deleting this object }

More RefPtr examples: RefPtr<DerivedRefObject> pObject2 = new DerivedRefObject; RefPtr<DerivedRefObject> pObject3 = pObject2; pObject2 = NULL; // pObject3 is still valid. pObject3->foo(); pObject3 = NULL; // Release the last reference to the object and the object is destroyed automatically.

Function Documentation

Get the calling module's HINSTANCE.

Returns: Handle pointing to the start of the calling module.

 {
     return reinterpret_cast<HINSTANCE>(&__ImageBase);
 }

◆ GetResourceStringAsMSTR() [1/4]

MSTR MaxSDK::GetResourceStringAsMSTR ( UINT resourceId )

inline

Extract a resource from the calling module's string table.

GetResourceStringAsMSTR is essentially a thread-safe wrapper around the Win32 API's LoadString, but it saves client code from the bother of dealing with its HINSTANCE, of maintaining a buffer, and reduces duplicated code.

Parameters

resourceId Identifier for the desired string resource within the calling module's string table.

Returns: An MSTR containing the resource string, empty if the requested resource is not found.

 {
     return MaxSDK::GetResourceStringAsMSTR(GetHInstance(), resourceId);
 }

◆ GetResourceStringAsMSTR() [2/4]

bool MaxSDK::GetResourceStringAsMSTR	(	UINT	resourceId,
		MSTR &	resourceString
	)

inline

Extract a resource from the calling module's string table.

GetResourceStringAsMSTR is essentially a thread-safe wrapper around the Win32 API's LoadString, but it saves client code from the bother of dealing with its HINSTANCE, of maintaining a buffer, and reduces duplicated code.

Parameters

resourceId	Identifier for the desired string resource within the calling module's string table.
resourceString	Updated to contain the resource string if the requested resource is not found.

Returns: true if the requested resource is found, false if not

 {

 }

◆ SortPolygonDiagonals() [1/2]

void MaxSDK::SortPolygonDiagonals ( geo::span< int > diag )

Puts diagonals in increase-by-last-index, decrease-by-first order.

This sorts the diagonals in the following fashion: each diagonal is reordered so that its smaller index comes first, then its larger. Then the list of diagonals is sorted so that it increases by second index, then decreases by first index. Such an ordered list for a 9-gon might be (1,3),(0,3), (0,4),(5,7),(4,7),(4,8). (This order is especially convenient for converting into triangles - it makes for a linear-time conversion.) SortPolygonDiagonals() uses qsort for speed.

Parameters

[in,out] diag The diagonals.

◆ SortPolygonDiagonals() [2/2]

void MaxSDK::SortPolygonDiagonals ( geo::span< uint64_t > diag )

◆ BestConvexDiagonals() [1/2]

		const BufferProxy< const Point3 > &	meshVertices,
		int *	diag
	)

Uses a triangulation scheme optimized for convex polygons to find a set of diagonals for this sequence of vertices, creating a triangulation for the polygon they form.

Face vertices are optional. If there is no index buffer, we assume they are trivial: 0, 1, 2, 3, 4, etc.

Parameters

[in]	faceVertexIndices	The face vertices in the sequence.
[in]	meshVertices	The array of vertices.
[out]	diag	A pointer to an array of size (deg-3)*2 where the diagonals can be put.

◆ BestConvexDiagonals() [2/2]

void MaxSDK::BestConvexDiagonals	(	const BufferProxy< const int > &	faceVertexIndices,
		const BufferProxy< const DPoint3 > &	meshVertices,
		int *	diag
	)

Uses a triangulation scheme optimized for convex polygons to find a set of diagonals for this sequence of vertices, creating a triangulation for the polygon they form.

◆ GetResourceStringAsMSTR() [3/4]

UtilExport MSTR MaxSDK::GetResourceStringAsMSTR	(	HINSTANCE	hinstance,
		UINT	resourceId
	)

Extract a resource from a module's string table.

GetResourceString is essentially a thread-safe wrapper around the Win32 API's LoadString, but it saves client code from the bother of maintaining a buffer and reduces duplicated code. Optimally, GetResourceString should be called through the single-parameter version from dllutilities.h.

Parameters

hinstance	Handle to the module whose string table will be queried for the resource.
resourceId	Identifier for the desired string resource within the calling module's string table.

Returns: An MSTR containing the resource string, empty if the requested resource is not found.

◆ GetResourceStringAsMSTR() [4/4]

GetResourceString is essentially a thread-safe wrapper around the Win32 API's LoadString, but it saves client code from the bother of maintaining a buffer and reduces duplicated code. Optimally, GetResourceString should be called through the single-parameter version from dllutilities.h.

Parameters

hinstance	Handle to the module whose string table will be queried for the resource.
resourceId	Identifier for the desired string resource within the calling module's string table.
resourceString	Updated to contain the resource string if the requested resource is not found.

Returns: true if the requested resource is found, false if not

◆ LoadMaxMultiResIcon()

CoreExport QIcon MaxSDK::LoadMaxMultiResIcon ( const QString & iconName )

Loads a set of Images into a multi-resolution QIcon.

This function looks into the UI_ln folder of the 3dsmax installation (or the internal Qt resource system) to find a set of matching image files to mark for usage. The actual images get loaded on demand.

The naming of those files has to match one of the following schemes:

[:/]Folder/BaseName[_on|_off][_size].ext

[:/]Folder/BaseName[_on|_off][_(width)x(height)].ext

x

controller mat max min numsubs x z controller keys x z controller keys x

Definition: generics.inl:212

So for example:

iconName	files on disk	QIcon entry size	QIcon state
Undo	Undo_16.png	16 x 16px	Off
Undo	Undo_off_24.png	24 x 24px	Off
Undo	Undo_on_32.png	32 x 32px	On
Undo	Undo_on_100.png	100 x 100px	On
Undo	Undo_16x32.png	16 x 32px	Off
Undo	Undo_on_16x32.png	16 x 32px	On

In that case a single call on LoadMaxMultiResIcon( "Undo" ) would produce an QIcon containing all the different sizes and states.

iconName	files on disk	QIcon entry size	QIcon state
Redo.png	Redo.png	based on file[^1]	Off
Redo.png	Redo_on.png	based on file[^1]	On

[^1]: This forces the QIcon to load the image file to determine its actual size.

iconName	files on disk	QIcon entry size	QIcon state
Fancy.jpg	Fancy_300x100.jpg	300 x 100px	Off
Fancy.jpg	Fancy_150x50.jpg	150 x 50px	Off

The iconName may also contain folders or sub-folders, so these fileNames are fine, too (slashes or backslashes can be used):

"SME/Editor.png" "SME/Nodes/Collapse.png" "SME\\Nodes\\RemoveItem.png"

Based on the current 3dsmax theme (Dark/Light) the icons are retrieved from different locations on the file-system, so depending on the setting "SME/Editor.png" may get:

UI_ln/Icons/Dark/SME/Editor*.png UI_ln/Icons/Light/SME/Editor*.png

If the iconName starts with ":/", it points to a Qt Resource like ":/Icons/Undo", the theming is not automatically applied, so the caller is responsible to actually provide the correct resource-bundle. Nevertheless the QIcons internal pixmap cache will be wiped on a theme change, so the next paint call on the QIcon will reload the acquired version.

If a size of an image inside an QIcon is not available but requested for painting, Qt will downscale the next bigger version automatically - but will never scale images up.

Parameters

[in] iconName The name of the icon to load. The path, basename and the extension of the file is used to find matching icons. The Extension may be omitted and .png is assumed to be the default extension.

Returns: A QIcon that contains all the images that matches the given iconName. Might be an empty QIcon if no match could be found.

See also: QIcon class in the Qt documentation, Qt Resource System

◆ CreateHICONFromMaxMultiResIcon() [1/2]

CoreExport HICON MaxSDK::CreateHICONFromMaxMultiResIcon	(	const MSTR &	iconName,
		int	width,
		int	height,
		bool	enabled = `true`,
		bool	on = `false`
	)

Create an HICON from a MaxMultiResIcon.

Loads a QIcon using LoadMaxMultiResIcon, and tries to extract a HICON from it using the given size, mode and state settings. For a detailed description on the iconName syntax, please have a closer look at the LoadMaxMultiResIcon function. The HICON returned might be smaller than requested, but never larger.

Convenience method for legacy usage, for example when using one size of a multi-resolution-icon in a win32 HMENU. Note that the resulting HICON wont refresh itself on a theme change, as the QIcon does.

Parameters

[in]	iconName	The name of the icon to load. This may be the actual filename, but also can be some folder/basename combination, as described in detail in LoadMaxMultiResIcon.
[in]	width	The (maximum) width of the image to be loaded.
[in]	height	The (maximum) height of the image to be loaded.
[in]	enabled	Sets, if an enabled or disabled version of the icon should be retrieved (QIcon::Normal vs QIcon::Disabled)
[in]	on	Sets, if the On or Off state of the icon should be retrieved (QIcon::On vs QIcon::Off).

Returns: A new HICON for the given parameters, if available, a nullptr otherwise. The HICON might be smaller than requested, but never larger.

◆ CreateHIMAGELISTFromMaxMultiResIcon()

CoreExport HIMAGELIST MaxSDK::CreateHIMAGELISTFromMaxMultiResIcon	(	const MSTR &	imageIconName,
		int	size,
		int	count,
		bool	alpha = `true`,
		bool	enabled = `true`,
		bool	on = `false`
	)

◆ QmaxMessageBox()

UtilExport int MaxSDK::QmaxMessageBox	(	QWidget *	parent,
		const QString &	text,
		const QString &	caption,
		unsigned int	type,
		unsigned int	exType = `0`,
		DWORD *	exRet = `nullptr`
	)

Provides an extended message box functionality. This is used to support message dialogs with a 'Hold', a 'Help' button and/or a 'Do not show this message again' check box.

The first four parameters correspond to the Win32 MessageBox method parameters, but not all Win32 MessageBox functionality is supported. The last two optional arguments add the extended functionality - exType is used for adding the additional buttons, and exRet is used for getting the extra return info. MaxSDK::MaxMessageBox and MaxSDK::QmaxMessageBox should be used in preference to Win32 MessageBox due to string clipping that can occur with Win32 MessageBox in some locales with some font types and sizes on Windows 10 when dpi scaling is greater than 100%.

Parameters

parent	- The parent QWidget
text	- The main message
caption	- The caption or title for the message window
type	- The type of message box. The supported types are: MB_YESNO MB_OK MB_YESNOCANCEL MB_OKCANCEL MB_ABORTRETRYIGNORE MB_RETRYCANCEL MB_CANCELTRYCONTINUE The following Win32 MessageBox flags are supported: MB_DEFBUTTON* MB_SYSTEMMODAL MB_TOPMOST The following Win32 MessageBox flags are not supported and will be ignored: MB_TASKMODAL MB_NOFOCUS MB_SETFOREGROUND MB_RIGHT MB_RTLREADING The MB_HELP flag is supported, albeit in a manner different than Win32 MessageBox. If specified and 'exRet' is not null, a Help button is displayed and clicking it causes 3ds Max Help to be displayed using the help topic id that is passed through 'exRet'. The MB_DEFBUTTON* flag applies to the standard message box buttons, and does not apply to the optional Help and Hold buttons
exType	- Used for adding additional UI elements. The supported bit field values are: MAX_MB_HOLD - display a 'Hold' button. MAX_MB_DONTSHOWAGAIN - display a 'Do not show this message again' check box
exRet	- Used for specifying the help file topic id and for returning extra info: if MAX_MB_DONTSHOWAGAIN is specified as part of 'exType', on return the MAX_MB_DONTSHOWAGAIN bit will or will not be set in 'exRet' based on check box setting. if MAX_MB_HOLD is specified as part of 'exType', if the button is pressed the MAX_MB_HOLD bit will set in 'exRet' and a value of IDOK is returned.

Note: See "https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-messagebox" for a description of the Win32 MessageBox method parameters.

◆ GetUIScaleFactor()

UtilExport float MaxSDK::GetUIScaleFactor ( int monitorID = -1 )

Returns the UI scaling factor relative to a default of 96 DPI.

The function reads the systems monitor settings and calculates the scaling factor based on the vertical logical DPI (what can be set and changed through the windows OS control panel). It will return 1.0f, if some value couldn't be retrieved or calculated, or a calculation result will be 0.0f; so it is safe to use the result of this function to simply multiply UI sizes without further checking.

Parameters

[in] monitorID The index of the monitor to get the actual logical vertical DPI from. Default value is set to -1, which means the primary system monitor.

Returns: The scaling factor, if it could be retrieved and calculated, 1.0f in other cases.

CoreExport void MaxSDK::ScaleFileOpenSaveDialogToolbar ( HWND hDlg )

Scales the toolbar size and icons in standard file open/save dialogs.

Scales the toolbar containing the 'Go To Last Folder Visisted', 'Up One Level', 'Create New Folder' buttons, and the 'View Menu' dropdown, by the system dpi scaling value. The hDlg parameter is HWND passed to the LPOFNHOOKPROC specified in the OPENFILENAME structure. Technically, this HWND is a child of the win32 file open / save dialog

static INT_PTR WINAPI MinimalMaxFileOpenHookProc( HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch(message)
    {
    case WM_INITDIALOG:
        MaxSDK::ScaleFileOpenSaveDialogToolbar(hDlg);
        ...

Parameters

[in] hDlg The dialog's HWND.

◆ MinimalMaxFileOpenHookProc()

CoreExport INT_PTR WINAPI MaxSDK::MinimalMaxFileOpenHookProc	(	HWND	hDlg,
		UINT	message,
		WPARAM	wParam,
		LPARAM	lParam
	)

A minimal LPOFNHOOKPROC for scaling the toolbar size and icons in standard file open/save dialogs.

Use this LPOFNHOOKPROC when not customization of the Open/Save File dialog is being performed.
Example usage:

OPENFILENAME   ofn;
memset(&ofn, 0, sizeof(ofn));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.Flags = OFN_HIDEREADONLY | OFN_EXPLORER | OFN_ENABLEHOOK | OFN_ENABLESIZING;
ofn.lpfnHook = (LPOFNHOOKPROC)MaxSDK::MinimalMaxFileOpenHookProc;
...
BOOL res = GetSaveFileName(&ofn);

Implementation:

INT_PTR WINAPI MinimalMaxFileOpenHookProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    if (message == WM_INITDIALOG)
        MaxSDK::ScaleFileOpenSaveDialogToolbar(hDlg);
    return FALSE;
}

◆ MaxMessageBox()

UtilExport int MaxSDK::MaxMessageBox	(	HWND	parent,
		LPCMSTR	text,
		LPCMSTR	caption,
		unsigned int	type,
		unsigned int	exType = `0`,
		DWORD *	exRet = `nullptr`
	)

Provides an extended message box functionality. This is used to support message dialogs with a 'Hold', a 'Help' button and/or a 'Do not show this message again' check box.

The first four parameters correspond to the Win32 MessageBox method parameters, but not all Win32 MessageBox functionality is supported. The last two optional arguments add the extended functionality - exType is used for adding the additional buttons, and exRet is used for getting the extra return info. MaxSDK::MaxMessageBox and MaxSDK::QmaxMessageBox should be used in preference to Win32 MessageBox due to string clipping that can occur with Win32 MessageBox in some locales with some font types and sizes on Windows 10 when dpi scaling is greater than 100%.

Parameters

parent	- The parent QWidget
text	- The main message
caption	- The caption or title for the message window
type	- The type of message box. The supported types are: MB_YESNO MB_OK MB_YESNOCANCEL MB_OKCANCEL MB_ABORTRETRYIGNORE MB_RETRYCANCEL MB_CANCELTRYCONTINUE The following Win32 MessageBox flags are supported: MB_DEFBUTTON* MB_SYSTEMMODAL MB_TOPMOST The following Win32 MessageBox flags are not supported and will be ignored: MB_TASKMODAL MB_NOFOCUS MB_SETFOREGROUND MB_RIGHT MB_RTLREADING The MB_HELP flag is supported, albeit in a manner different than Win32 MessageBox. If specified and 'exRet' is not null, a Help button is displayed and clicking it causes 3ds Max Help to be displayed using the help topic id that is passed through 'exRet'. The MB_DEFBUTTON* flag applies to the standard message box buttons, and does not apply to the optional Help and Hold buttons
exType	- Used for adding additional UI elements. The supported bit field values are: MAX_MB_HOLD - display a 'Hold' button. MAX_MB_DONTSHOWAGAIN - display a 'Do not show this message again' check box
exRet	- Used for specifying the help file topic id and for returning extra info: if MAX_MB_DONTSHOWAGAIN is specified as part of 'exType', on return the MAX_MB_DONTSHOWAGAIN bit will or will not be set in 'exRet' based on check box setting. if MAX_MB_HOLD is specified as part of 'exType', if the button is pressed the MAX_MB_HOLD bit will set in 'exRet' and a value of IDOK is returned.

Note: See "https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-messagebox" for a description of the Win32 MessageBox method parameters.

◆ SearchComboBox()

CoreExport bool MaxSDK::SearchComboBox	(	HWND	hWnd,
		MCHAR	key,
		const MCHAR *	szTrim = `NULL`
	)

Multiple character search for ComboBoxes.

This method will select an entry in the ComboBox based on the multiple key entries over a set time period. The functionality mimics the standard windows ListView behavior, including the documented one second time period for key entries. It is intended to be used in conjunction with the WM_CHAR message in the ComboBox's callback.

Example usage:

case WM_CHAR:

return MaxSDK::SearchComboBox( hWnd, (MCHAR)wParam, _M(" "));

This method will select an entry in the ListBox based on the multiple key entries over a set time period. The functionality mimics the standard windows ListView behavior, including the documented one second time period for key entries. It is intended to be used in conjunction with the WM_CHAR message in the ListBox's callback.

Example usage:

case WM_CHAR:

return MaxSDK::SearchListBox( hWnd, (MCHAR)wParam, _M(" "));

MaxSDK::SearchListBox

CoreExport bool SearchListBox(HWND hWnd, MCHAR key, const MCHAR *szTrim=NULL)

Multiple character search for ListBoxes.

Parameters

[in]	hWnd	Window handle of ListBox
[in]	key	Character entered by user
