调整大小ToolStripButtons适合完整的背景图片 [英] Resizing ToolStripButtons to fit complete BackGround image
问题描述
我的目标是在toolStripButton和toolStripDropDownButton完全契合的形象。
My goal is totally fit image in toolStripButton and toolStripDropDownButton.
如果在按钮设置图像属性中的形象,我不能完全适合按钮的图像。因为空白,边框,什么按钮的。(我不知道到底)。
If a image in the button set with image property, I can not totally fit the image in the button. Because of margin, border, or something of the button.(I don't know exactly).
所以我尝试设置图像与BackgroudImage属性的按钮。之后,我调整了部分物业(如自动调整大小,大小等...),我可以在按钮适合的形象。
So I try to set the image in the button with BackgroudImage property. After I adjust some property(like AutoSize, Size and so on...), I can fit image in button.
但在这种情况下,也看不出背景图像。它消失,当鼠标光标位于按钮。
but in this case, I can not see background image. It is disappear, when the mouse cursor is located in the button.
我该如何解决这个问题?
How can I solve this problem??
图片属性。我不能删除图像之间的差距。
Image Property. I can not remove the gap between images.
BackgroundImage属性。我看不到图像,当鼠标光标在图像上。
BackgroundImage Property. I can not see the image, when mouse cursor is on the image.
推荐答案
好了,你发现它为什么留下周围的图像属性的空间。可以通过分配ToolStrip.Renderer属性定制按钮的呈现。这可能是这个样子:
Well, you found out why it leaves a space around the Image property. You can customize the rendering of the button by assigning the ToolStrip.Renderer property. That could look something like this:
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
toolStrip1.Renderer = new MyRenderer();
}
private class MyRenderer : ToolStripProfessionalRenderer {
protected override void OnRenderButtonBackground(ToolStripItemRenderEventArgs e) {
if (e.Item.BackgroundImage == null) base.OnRenderButtonBackground(e);
else {
Rectangle bounds = new Rectangle(Point.Empty, e.Item.Size);
e.Graphics.DrawImage(e.Item.BackgroundImage, bounds);
if (e.Item.Pressed) {
// Something...
}
else if (e.Item.Selected) {
// Something...
}
using (Pen pen = new Pen(Color.Black)) {
e.Graphics.DrawRectangle(pen, bounds.X, bounds.Y, bounds.Width - 1, bounds.Height - 1);
}
}
}
}
}
您将必须填写// ...东西线和做一些图纸,使得它明显,按钮pssed或选择$ P $用户。也许画了厚厚的钢笔一个矩形,它是由你。
You'll have to fill in the // Something... lines and do some kind of drawing that makes it obvious to the user that the button is pressed or selected. Maybe draw a rectangle with a thick Pen, it is up to you.
