Detailed Description

Internal use only. Hidden internal implementation for ToolTipExtender.

See also

Class ToolTipExtender.

Description:

This class allows a developer to add tooltips to one or more window controls. Controls of all types are supported. One extender object can support all tooltips for a dialog, it's not necessary to create one extender per tooltip. This is useful for control types which do not have native tooltip support.

Constructor & Destructor Documentation

ToolTipExtender()

CoreExport ToolTipExtender

(

)

Class constructor.

No heap memory is allocated until tooltips are actually set.

~ToolTipExtender()

virtual CoreExport ~ToolTipExtender ( )

virtual

Class destructor.

Removes all tooltips and releases heap memory.

Member Function Documentation

SetToolTip()

virtual CoreExport void SetToolTip ( HWND  hWnd, const MSTR &  toolTipIn  )

virtual

Sets a tooltip for an arbitrary UI control.

Calling this twice for a single control is safe, and will remove the first tooltip. Calling this for multiple controls is allowed, as this class supports an unlimited number of tooltips. Note that tooltip resources are not automatically freed when a control is destroyed. Resources are freed when the extender is destroyed, or by calling RemoveToolTip() or Reset().

Parameters

hWnd	Handle to the window control.
toolTipIn	ToolTip string. The string is copied, so the caller may safely delete this.

GetToolTip()

virtual CoreExport void GetToolTip ( HWND  hWnd, MSTR &  toolTipOut  )

virtual

Gets the tooltip for an arbitrary UI control.

This only functions for tooltips set with this class. Returns an empty string if no tooltip is set.

Parameters

hWnd	Handle to the window control.
toolTipOut	ToolTipOutput string. The method will resize the string as necessary.

RemoveToolTip()

virtual CoreExport void RemoveToolTip ( HWND  hWnd )

virtual

Removes the tooltip from an arbitrary UI control.

This only functions for tooltips set with this class. Note that tooltip resources are not automatically freed when a control is destroyed. Resources are freed when the extender is destroyed, or by calling this function or Reset().

Parameters

hWnd	Handle to the window control.

RemoveToolTips()

virtual CoreExport void RemoveToolTips ( )

virtual

Removes all tooltips and releases heap memory.

GetToolTipHWND()

virtual CoreExport HWND GetToolTipHWND ( )

virtual

Returns a handle to the operating system's ToolTip object.

This provides access to extended tooltip functionality. See the operating system's documentation for TOOLTIPS_CLASS.
