Hi,

I was just wondering, is there an API that answers the question if a given style flag/hint
is supported on the current platform? I want to show an own icon if SWT.ICON_SEARCH for
SWT.Text is not supported. I just wrote a helper method to do this:
http://github.com/ralfebert/rcputils/blob/2.0.2/de.ralfebert .rcputils/src/de/ralfebert/rcputils/porting/CrossPlatformSup port.java

Is there a better way?

Greetings,

Ralf

Hi Ralf,

You can check the Control's style after creation to see if the bit was
retained or not. For example:

public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
int style = SWT.SEARCH | SWT.ICON_CANCEL | SWT.ICON_SEARCH;
System.out.println("old: " + style);
Text text = new Text(shell, style);
System.out.println("new: " + (text.getStyle() & style)); // <---
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
