我有一个用作一个单选按钮ToolStripButton。当检查,一个蓝色的轮廓包围按钮,但没有背景颜色。这是不够明确为被选中的按钮的用户,所以我想改变背景颜色,使检查状态更加明显。
我如何去改变高亮颜色当Checked属性设置为true?
下面是一个code片断:
this.hideInactiveVehiclesToolstripButton.CheckOnClick = TRUE;
this.hideInactiveVehiclesToolstripButton.ForeColor = System.Drawing.Color.Blue;
this.hideInactiveVehiclesToolstripButton.AutoSize = FALSE;
this.hideInactiveVehiclesToolstripButton.DisplayStyle = System.Windows.Forms.ToolStripItemDisplayStyle.Image;
this.hideInactiveVehiclesToolstripButton.Image =全球:: ClientUI.Properties.Resources.toggleInactive;
this.hideInactiveVehiclesToolstripButton.ImageTransparentColor = System.Drawing.Color.Black;
this.hideInactiveVehiclesToolstripButton.Name =hideInactiveVehiclesToolstripButton;
this.hideInactiveVehiclesToolstripButton.Size =新System.Drawing.Size(48,48);
this.hideInactiveVehiclesToolstripButton.Text =隐藏不活动的车辆;
this.hideInactiveVehiclesToolstripButton.Click + =新System.EventHandler(this.hideInactiveVehiclesToolstripButton_Click);
解决方案
您可以提供自己的工具条渲染器来绘制按钮的背景,你想要的方式。这个例子code给出的检查按钮,一个非常明显的黑色背景:
公共部分Form1类:表格{
公共Form1中(){
的InitializeComponent();
toolStrip1.Renderer =新MyRenderer();
}
私有类MyRenderer:ToolStripProfessionalRenderer {
保护覆盖无效OnRenderButtonBackground(ToolStripItemRenderEventArgs E){
VAR BTN = e.Item为ToolStripButton;
如果(BTN = NULL和放大器;!&安培; btn.CheckOnClick和放大器;&安培; btn.Checked){
矩形范围=新的Rectangle(Point.Empty,e.Item.Size);
e.Graphics.FillRectangle(Brushes.Black,界限);
}
其他base.OnRenderButtonBackground(E);
}
}
}
I have a ToolStripButton that is used as a radio button. When it is checked, a blue outline surrounds the button, but there is no background color. It is not clear enough for the user that the button is checked, so I would like to change the background color to make the check state more visible.
How do I go about changing the highlight color when the Checked property is set to true?
Here is a code snippet:
this.hideInactiveVehiclesToolstripButton.CheckOnClick = true;
this.hideInactiveVehiclesToolstripButton.ForeColor = System.Drawing.Color.Blue;
this.hideInactiveVehiclesToolstripButton.AutoSize = false;
this.hideInactiveVehiclesToolstripButton.DisplayStyle = System.Windows.Forms.ToolStripItemDisplayStyle.Image;
this.hideInactiveVehiclesToolstripButton.Image = global::ClientUI.Properties.Resources.toggleInactive;
this.hideInactiveVehiclesToolstripButton.ImageTransparentColor = System.Drawing.Color.Black;
this.hideInactiveVehiclesToolstripButton.Name = "hideInactiveVehiclesToolstripButton";
this.hideInactiveVehiclesToolstripButton.Size = new System.Drawing.Size(48, 48);
this.hideInactiveVehiclesToolstripButton.Text = "Hide Inactive Vehicles";
this.hideInactiveVehiclesToolstripButton.Click +=new System.EventHandler(this.hideInactiveVehiclesToolstripButton_Click);
解决方案
You can provide your own tool strip renderer to draw the button's background the way you want them. This example code gives the checked button a very visible black background:
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
toolStrip1.Renderer = new MyRenderer();
}
private class MyRenderer : ToolStripProfessionalRenderer {
protected override void OnRenderButtonBackground(ToolStripItemRenderEventArgs e) {
var btn = e.Item as ToolStripButton;
if (btn != null && btn.CheckOnClick && btn.Checked) {
Rectangle bounds = new Rectangle(Point.Empty, e.Item.Size);
e.Graphics.FillRectangle(Brushes.Black, bounds);
}
else base.OnRenderButtonBackground(e);
}
}
}
