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

ImageAlign、Image、ImageIndexImageKey和ImageScaling属性与图像处理的各个方面有关。 通过直接设置这些属性或设置仅ImageList运行时属性，在控件中使用ToolStrip图像。

图像缩放由两者ToolStripToolStripItem中的属性交互决定，如下所示：

• ImageScalingSize 是最终映像的规模，由映像 ImageScaling 设置和容器 AutoSize 设置的组合决定。

  • true 如果AutoSize (默认) 且ToolStripItemImageScalingSizeToFit不发生图像缩放，并且ToolStrip大小为最大项或规定的最小大小。

  • 如果是AutoSize且ToolStripItemImageScaling不是None，则不会发生图像和ToolStrip缩放。false
