COOLBAR Problem

[danireb]

Hi,

I only want to make in a SWT WindowsApplication a coolbar.

Everything is ok while I am designing, and previewing the result.

The coolbar consist in 2 coolitems with ToolBars. Each ToolBar with 2 ToolItems. The ToolItems has an image but no text.

When I run the application, always the last image (toolItem) of the first CoolItem desappear. It is hidden. I had to move the second CoolItem in order to view that ToolItem. But i dont undestand why when i see the form in the designer, it is ok.

thanks in advance

I have no idea. I tried a simple example based on what you described above and it looked fine both in Designer and at runtime.

If you want to provide a test case, we can look into it further.

You might also consider submitting a bug report to Eclipse.org since the runtime behavior of the Coolbar would be an Eclipse SWT issue that we could do little about even if we could reproduce it.

I "fix" the problem.

In windows/Preferences in Eclipse, in the Designer preferences. I checked "Create every component in its own block" and then all started to work fine.

I dont know if that was the solution, but it works for me.

Hmmm. That should not have any effect at all. In my example, that option was turned off.

We would really need to see your original code in order to try and reproduce the problem (or tell you why it is occurring).

Here is the code.

Now, there are 3 toolItem and 2 toolBar and 2 Coolbar.

In the designer and when i test de form, i dont see the second image. but when i run from eclipse the application, it appears. i cant see the image that i cant see in the design.

(THE OPTION IN THE PREFERENCES IN UNCHECKED)

package src;

import org.eclipse.swt.SWT;

import org.eclipse.swt.widgets.CoolItem;
import org.eclipse.swt.widgets.Display;

public class Interface {

   protected Shell shell;

   /**
    * Launch the application

   public static void main(String[] args) {
      try {
         Interface window = new Interface();
         window.open();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

   /**
    * Open the window

   public void open() {
      final Display display = Display.getDefault();
      createContents();
      shell.open();
      shell.layout();
      while (!shell.isDisposed()) {
         if (!display.readAndDispatch())
            display.sleep();
      }
   }

   /**
    * Create contents of the window
    */
   protected void createContents() {
      shell = new Shell();
      shell.setSize(500, 375);
      shell.setText("SWT Application");

      final CoolBar coolBar = new CoolBar(shell, SWT.NONE);
      coolBar.setBounds(0, 0, 205, 22);

      final CoolItem newItemCoolItem = new CoolItem(coolBar, SWT.PUSH);
      newItemCoolItem.setText("New item");

      final ToolBar toolBar = new ToolBar(coolBar, SWT.FLAT);
      newItemCoolItem.setControl(toolBar);

      final ToolItem newItemToolItem = new ToolItem(toolBar, SWT.PUSH);
      newItemToolItem.setImage(SWTResourceManager.getImage(Interface.class,
            "icons/debug_exec.gif"));

      final ToolItem newItemToolItem_1 = new ToolItem(toolBar, SWT.PUSH);
      newItemToolItem_1.setImage(SWTResourceManager.getImage(Interface.class,
            "icons/new_wiz.gif"));
      //

      SWTResourceManager.fixCoolBarSize(coolBar);

      final CoolItem newItemCoolItem_1 = new CoolItem(coolBar, SWT.PUSH);
      newItemCoolItem_1.setText("New item");

      final ToolBar toolBar_1 = new ToolBar(coolBar, SWT.FLAT);
      newItemCoolItem_1.setControl(toolBar_1);

      final ToolItem newItemToolItem_2 = new ToolItem(toolBar_1, SWT.PUSH);
      newItemToolItem_2.setImage(SWTResourceManager.getImage(Interface.class,
            "icons/prop_ps.gif"));
   }

}

Sometimes, i dont see the image in the designer nor when i run the application. And sometimes i see all the images in the designer, but when i run the application, it desappears. (This things happened to me in different projects)

I hope for your response.

Thanks

I tried your example and it worked fine on my end. You did not include any images, so I had to use my own.

Does it matter which images you use? IOW, is the problem associated with specific images?

If the problem also occurs at runtime, this is a clear indication that this is an Eclipse problem rather than a Designer problem. Yoiu should package up a test case and submit a bug report to Eclipse.org.

OK.

Thanks for your response. I will report this debug to Eclipse.

But, I insist that something wrong is with my plugin, elipse or SWT designer, because if I copy the source above and paste it in a new class. The problem persists. I cant see the images in the SWT Designer but when I run de SWT Application, the image appears.

I set a lot of different images in the button, so I discard the that the images are the problem.

There are 2 situations:

When everything is OK in the SWT Designer, when I run the application, some coolitems are hidden behind others.

When I run the application and everything is OK, in the SWT Designer I cant see the coolitem.

Thanks, I will still trying...

Unfortunately, without a reproduceable test case, there is very little we can do to help.
