単純な DotNet MonthCalendar の作成と色の変更

以下の例は、MonthCalendar dotNet コントロールを使用して単純なダイアログを作成し、プロパティ、メソッド、およびイベントを出力する mousedown イベント ハンドラを割り当てています。

例: 

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

評価を行った後、今月のカレンダーの DotNet コントロールのダイアログ ボックスが既定の設定を使用して表示されます。dotnet.showconstructors() メソッドを使用して、このコントロールのコンストラクタを確認することができます。

例: 

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

カラーを変更してカレンダーの外観を変更することもできます。

例: 

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

色のプロパティ自体にもプロパティがあり、そのうちのいくつか代表的な色が読み込み専用で定義されています。つまり、.ForeColor プロパティおよび .BackColor プロパティを、既に定義されている静的な読み込み専用の値に設定すればよいのです。 

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

ユーザ定義のカラーの使用

プリセットを使用する代わりに、独自の DotNet カラーを作成することができます。

System.Drawing.Color オブジェクトが公開するメソッドを以下に示します。 

showMethods test.f1.backcolor
.<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

上記から分かるとおり、 .FromARGB() メソッドでは、Red、Green、および Blue の値を指定できます。 また、このメソッドにより、次のように DotNet カラー値を構築できます。 

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