.NET Framework クラス ライブラリ リファレンス

FontDialog.MinSize プロパティ

ユーザーが選択できるポイント サイズの最小値を取得または設定します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Property MinSize As
 Integer

Visual Basic (使用法)

Dim instance As FontDialog
Dim value As Integer

value = instance.MinSize

instance.MinSize = value

C#

public int MinSize { get;
 set; }

C++

public:
property int MinSize {
    int get ();
    void set (int value);
}

J#

/** @property */
public int get_MinSize ()

/** @property */
public void set_MinSize (int
 value)

JScript

public function get MinSize
 () : int

public function set MinSize
 (value : int)

プロパティ値
ユーザーが選択できるポイント サイズの最小値。既定値は 0 です。

解説

ポイント サイズの最大値と最小値の設定を有効にするためには、MaxSize の値が MinSize の値よりも大きく、さらに両方の値が 0 より大きい値である必要があります。

このプロパティの値を 0 より小さい値に設定しても、実際には 0 が使用されます。MinSize に MaxSize を超える値を設定すると、MaxSize は MinSize に設定されます。MinSize および MaxSize 同じ値に設定すると、選択できるフォント サイズが 1 つに限定されます。

ポイント サイズを 0 にした場合は、フォント サイズは制限されません。

使用例

MinSize、MaxSize、ShowEffects、FontMustExist の各メンバを使用する方法、および Apply イベントを処理する方法を次のコード例に示します。この例を実行するには、FontDialog1 という名前の FontDialog と Button1 という名前の Button が配置されているフォームに次のコードを貼り付けます。

Visual Basic

Private Sub Button1_Click(ByVal
 sender As System.Object, _
    ByVal e As System.EventArgs) Handles
 Button1.Click

    ' Set FontMustExist to true, which causes message box error
    ' if the user enters a font that does not exist. 
    FontDialog1.FontMustExist = True

    ' Set a minimum and maximum size to be
    ' shown in the FontDialog.
    FontDialog1.MaxSize = 32
    FontDialog1.MinSize = 18

    ' Show the Apply button in the dialog.
    FontDialog1.ShowApply = True

    ' Do not show effects such as Underline
    ' and Bold.
    FontDialog1.ShowEffects = False

    ' Save the existing font.
    Dim oldFont As System.Drawing.Font = Me.Font

    ' Show the dialog and save the result.
    Dim result As DialogResult = FontDialog1.ShowDialog()

    ' If The OK button in the Font dialog box is clicked, 
    ' set all the controls' fonts to the chosen font by
    ' calling the FontDialog1_Apply method.
    If result = DialogResult.OK Then
        FontDialog1_Apply(Me.Button1, New System.EventArgs)

        ' If the Cancel button is clicked, set the controls'
        ' fonts back to the original font.
    ElseIf (result = DialogResult.Cancel) Then
