Bug 445800

Description Gulfstream Wang 2014-10-02 11:54:18 EDT

When I run SWT4.4 (also with 4.5M2) with GTK 3, I get a error message in the console. The error message is:

(Test SWT:5234): Gtk-CRITICAL **: gtk_hsv_to_rgb: assertion 's >= 0.0 && s <= 1.0' failed 

Even the most simple SWT program, sunch as the blew:

package testswt;

import org.eclipse.jface.window.*;
import org.eclipse.swt.widgets.*;


public class CTestSWT extends ApplicationWindow
{
    public static void main(String[] args)
    {
        Display.setAppName("Test SWT");
       
        CTestSWT frObj = new CTestSWT();
        frObj.setBlockOnOpen(true);
        frObj.open();
        Display.getCurrent().dispose();
    }
    
    public CTestSWT()
    {
        super(null);
    }
    
    @Override
    protected Control createContents(Composite parent)
    {
        getShell().setText("Test SWT");
        getShell().setSize(300, 300);
        getShell().setLocation(200, 200);
       
        return parent;
    }
} 

To this most simple SWT program, this error does not present any wrong with the GUI. But to some dialog, I get the wrong display as fig_error.png (in attachments) while I execute it with GTK 3.

My GTK 3 version is 3.12.2.
