Creating A Simple DotNet MonthCalendar And Changing Its Colors

The following example creates a simple dialog with a MonthCalendar dotNet control and assigns a mousedown event handler that prints the properties, methods, and events:

EXAMPLE

   rollout test "test" height:200 width:220
   (
       dotNetControl f1 "MonthCalendar" align:#left height:180 width:200
       on f1 mousedown val do
       (
           format "in mousedown handler: arg: %\n" val
           format "showproperties:\n"
           showproperties val
           format "showmethods:\n"
           showmethods val
           format "showevents:\n"
           showevents val
           format "getpropnames : %\n" (getpropnames val)
           format "prop values:\n"
       )
   )
   createdialog test escapeEnable:true

After evaluation, a dialog showing a Month Calendar DotNet Control is displayed with default settings. You can see the constructor of the control using the dotnet.showconstructors() method:

EXAMPLE

   --see the constructor of the control
   dotnet.showConstructors test.f1
   System.Windows.Forms.MonthCalendar()
   true

You can also change the calendar's appearance by modifying its colors.

EXAMPLE

   --First we list all properties of the control
   --and look to find those controlling some of its colors:

   true

The color property itself has properties, some of them read-only definitions of typical colors. This means that you can set the .ForeColor and .BackColor properties to the static read-only values that are already defined:

   test.f1.ForeColor = test.f1.ForeColor.Blue
   --> dotNetObject:System.Drawing.Color
   test.f1.BackColor = test.f1.BackColor.Yellow
   --> dotNetObject:System.Drawing.Color
   test.f1.TitleBackColor = test.f1.TitleBackColor.Tomato
   --> dotNetObject:System.Drawing.Color

Using User-Defined Colors

You can create your own DotNet colors instead of using the presets.

Take a look at the methods that a System.Drawing.Color object exposes:

   showMethods test.f1.backcolor
   .<System.Boolean>Equals <System.Drawing.Color>other
   .<System.Boolean>Equals <System.Object>obj
   .[static]<System.Boolean>Equals <System.Object>objA <System.Object>objB
   .[static]<System.Drawing.Color>FromArgb <System.Int32>argb
   .[static]<System.Drawing.Color>FromArgb <System.Int32>alpha <System.Drawing.Color>baseColor
   .[static]<System.Drawing.Color>FromArgb <System.Int32>red <System.Int32>green <System.Int32>blue
   .[static]<System.Drawing.Color>FromArgb <System.Int32>alpha <System.Int32>red <System.Int32>green <System.Int32>blue
   .[static]<System.Drawing.Color>FromKnownColor <System.Drawing.KnownColor>color
   .[static]<System.Drawing.Color>FromName <System.String>name
   .<System.Single>GetBrightness()
   .<System.Int32>GetHashCode()
   .<System.Single>GetHue()
   .<System.Single>GetSaturation()
   .<System.Type>GetType()
   .[static]<System.Boolean>ReferenceEquals <System.Object>objA <System.Object>objB
   .<System.Int32>ToArgb()
   .<System.Drawing.KnownColor>ToKnownColor()
   .<System.String>ToString()
   true

As you can see, the .FromARGB() method allows to provide Red, Green, and Blue values, and it constructs a DotNet color value:

   test.f1.forecolor = test.f1.backcolor.FromArgb 255 255 100
   test.f1.backcolor = test.f1.backcolor.FromArgb 100 200 234
   dotNetObject:System.Drawing.Color
