[platform-swt-dev] Text background color

[Stéphane WASSERHARDT <stephane.wasserhardt@xxxxxxxxxxxx>]

Hello all !

 

I found a strange behaviour of the « Text » widget today :

When it’s not editable (setEditable(false)), the background color of the widget becomes gray (at least on windows, which is the OS I use).

Then if I query this background color, it returns the “editable” background color : white (instead of gray !)

Maybe this is the expected behaviour, but then, how can I properly get the “non-editable” background color ?

 

Here is a snippet demonstrating the problem :

 

import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.RowLayout;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Label;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Text;

 

public class BackgroundTest {

     

      public static void main (String [] args) {

            Display display = new Display();

            Shell shell = new Shell(display);

            RowLayout layout = new RowLayout();

            layout.wrap = true;

            shell.setLayout(layout);

           

            // Shows a simple editable text widget  

Text textE = new Text (shell, SWT.BORDER);

            textE.setText ("editable");

            // Shows a label with background color set to the text’s background color

            Label labelE = new Label (shell, SWT.BORDER);

            labelE.setText("editable\nbackground");

            labelE.setBackground(textE.getBackground());

           

            // Shows a simple non-editable text widget    

            Text textNE = new Text (shell, SWT.BORDER);

            textNE.setEditable(false);

            textNE.setText ("non-editable");

            // Shows a label with background color set to the non-editable text’s background color

            Label labelNE = new Label (shell, SWT.BORDER);

            labelNE.setText("non-editable\nbackground");

            labelNE.setBackground(textNE.getBackground());

            // THIS LABEL’S BACKGROUND COLOR IS WHITE !

            // IT SHOULD BE GRAY !!!!

 

            shell.pack();

            shell.open();

            while (!shell.isDisposed()) {

                  if (!display.readAndDispatch())

                        display.sleep();

            }

            display.dispose();

      }

 

}

 

Thanks in advance for your help !
