示例

下面的代码示例演示如何设置Image和ImageScalingImageTransparentColor设置 aToolStripItem。 此外，它还演示了如何设置和显示项目的自定义工具提示。

ToolStripButton^ imageButton;

void InitializeImageButtonWithToolTip()
{

    // Construct the button and set the image-related properties.
    imageButton = gcnew ToolStripButton;
    imageButton->Image = 
        gcnew Bitmap(Timer::typeid,"Timer.bmp");
    imageButton->ImageScaling = 
        ToolStripItemImageScaling::SizeToFit;

    // Set the background color of the image to be transparent.
    imageButton->ImageTransparentColor = 
        Color::FromArgb(0, 255, 0);

    // Show ToolTip text, set custom ToolTip text, and turn
    // off the automatic ToolTips.
    toolStrip1->ShowItemToolTips = true;
    imageButton->ToolTipText = "Click for the current time";
    imageButton->AutoToolTip = false;

    // Add the button to the ToolStrip.
    toolStrip1->Items->Add(imageButton);
}


//   internal:

internal ToolStripButton imageButton;

private void InitializeImageButtonWithToolTip()
{

    // Construct the button and set the image-related properties.
    imageButton = new ToolStripButton();
    imageButton.Image = new Bitmap(typeof(Timer), "Timer.bmp");
    imageButton.ImageScaling = ToolStripItemImageScaling.SizeToFit;

    // Set the background color of the image to be transparent.
    imageButton.ImageTransparentColor = Color.FromArgb(0, 255, 0);

    // Show ToolTip text, set custom ToolTip text, and turn
    // off the automatic ToolTips.
    toolStrip1.ShowItemToolTips = true;
    imageButton.ToolTipText = "Click for the current time";
    imageButton.AutoToolTip = false;

    // Add the button to the ToolStrip.
    toolStrip1.Items.Add(imageButton);
}

Friend WithEvents imageButton As ToolStripButton

Private Sub InitializeImageButtonWithToolTip()

    ' Construct the button and set the image-related properties.
    imageButton = New ToolStripButton()
    imageButton.Image = New Bitmap(GetType(Timer), "Timer.bmp")
    imageButton.ImageScaling = ToolStripItemImageScaling.SizeToFit

    ' Set the background color of the image to be transparent.
    imageButton.ImageTransparentColor = Color.FromArgb(0, 255, 0)

    ' Show ToolTip text, set custom ToolTip text, and turn
    ' off the automatic ToolTips.
    toolStrip1.ShowItemToolTips = True
    imageButton.ToolTipText = "Click for the current time"
    imageButton.AutoToolTip = False

    ' Add the button to the ToolStrip.
    toolStrip1.Items.Add(imageButton)

End Sub

注解

ToolStripItem 使用属性 Text 作为内容的默认源 ToolTip 。 设置为AutoToolTipfalse用作ToolTipText内容的源ToolTip。

若要使用此属性，还必须设置为 ShowItemToolTips true。
