NSButton with image - how to get image subview?
题
I can't find, how to get image subview from NSButton
. I need it to get actual image scale.
解决方案
There is no subview, it is painted by button cell. Use e.g. -[NSCell imageRectForBounds:]
to get information about its position.
其他提示
You can loop through the button subview and you will see NSImageView & NSTextfield. Something like this pseudo code:
foreach (NSView view in Subviews)
if (view.GetType() == typeof(NSImageView))
imageView = (NSImageView)view;
else if (view.GetType() == typeof(NSTextField))
textField = (NSTextField)view;
