问题描述
我米坚持一个问题。我想改变按钮的背景图像上运行。我得到了改变颜色的解决方案,但我想改变形象。
在code如下:
公共无效buttonCase(对象发件人,RoutedEventArgs E)
{
开放的我们的uri = NULL;
VAR形象=新的ImageBrush();
如果(((APP)App.Current).appControler.m_Mode == Controller.textMode.Letters)
{
((APP)App.Current).appControler.buttonCase(发件人,E);
开关(((APP)App.Current).appControler.m_case)
{
案例Controller.caseMode.Upper:
b0.FontSize = b1.FontSize = b2.FontSize = b3.FontSize = b4.FontSize = b5.FontSize = b6.FontSize = b7.FontSize
= b8.FontSize = b9.FontSize = bCornerLower.FontSize = 30.0;
URI =新的URI(@/来源$ C $ C,分量/图片/ Lower_Case_p.png,UriKind.Relative);
image.ImageSource =新的BitmapImage(URI);
btnCase.Background =图像;
打破;
案例Controller.caseMode.Lower:
b0.FontSize = b1.FontSize = b2.FontSize = b3.FontSize = b4.FontSize = b5.FontSize = b6.FontSize = b7.FontSize
= b8.FontSize = b9.FontSize = bCornerLower.FontSize = 40.0;
URI =新的URI(@/来源$ C $ C,分量/图片/ Case_p.png,UriKind.Relative);
image.ImageSource =新的BitmapImage(URI);
btnCase.Background =图像;
打破;
}
}
}
解决方案
这样的事情?
VAR刷=新的ImageBrush();
brush.ImageSource =新的BitmapImage(新的URI(@图像/ myImage.png,UriKind.Relative));
myButton.Background =刷;
我做了一个测试应用程序与两个图像。我切换按钮点击图像和它的作品。
私人布尔标志;
私人无效的button1_Click(对象发件人,RoutedEventArgs E)
{
标志=标志!;
VAR uriString中=标志? @图像/ logo.png:@图像/的icon.png;
myButton.Background =新的ImageBrush
{=的ImageSource新的BitmapImage(新的URI(uriString中,UriKind.Relative))};
}
I m stuck with a problem. I want to change the background image of button on runtime. I got the solution for changing the color but i want to change the image.
The code is as follows
public void buttonCase(object sender, RoutedEventArgs e)
{
Uri uri = null;
var image = new ImageBrush();
if (((App)App.Current).appControler.m_Mode == Controller.textMode.Letters)
{
((App)App.Current).appControler.buttonCase(sender, e);
switch (((App)App.Current).appControler.m_case)
{
case Controller.caseMode.Upper:
b0.FontSize = b1.FontSize = b2.FontSize = b3.FontSize = b4.FontSize = b5.FontSize = b6.FontSize = b7.FontSize
= b8.FontSize = b9.FontSize = bCornerLower.FontSize = 30.0;
uri = new Uri(@"/SourceCode;component/Images/Lower_Case_p.png", UriKind.Relative);
image.ImageSource = new BitmapImage(uri);
btnCase.Background = image;
break;
case Controller.caseMode.Lower:
b0.FontSize = b1.FontSize = b2.FontSize = b3.FontSize = b4.FontSize = b5.FontSize = b6.FontSize = b7.FontSize
= b8.FontSize = b9.FontSize = bCornerLower.FontSize = 40.0;
uri = new Uri(@"/SourceCode;component/Images/Case_p.png", UriKind.Relative);
image.ImageSource = new BitmapImage(uri);
btnCase.Background = image;
break;
}
}
}
解决方案
Something like this?
var brush = new ImageBrush();
brush.ImageSource = new BitmapImage(new Uri(@"Images/myImage.png", UriKind.Relative));
myButton.Background = brush;
[Edit] I made a test application with two images. I toggle the image on button click and it works.
private bool flag;
private void button1_Click(object sender, RoutedEventArgs e)
{
flag = !flag;
var uriString = flag ? @"Images/logo.png" : @"Images/icon.png";
myButton.Background = new ImageBrush
{ ImageSource = new BitmapImage(new Uri(uriString, UriKind.Relative)) };
}
