Have Dialog Resize by content

[nbuesing]

I create a dialog and display it. I close the dialog and before opening again the content changes (so it needs a larger window to display it). However, I can not get the dialog to resize, I must explicitly size it.

I try doing dialog.forceLayout(), dialog.setPixelSize(-1,-1)/dialog.forceLayout(), etc. Nothing seems to work for me.

The dialog sizing is as desired the first time, but not the following times.

What am I missing with the GXT Dialog widget?

Thanks.

Did you ever get a response? I am having similar issues with my Dialog.

This has been fixed in version GXT 3.0.6.

After the layout changes call:

autoSize.forceLayout().

    finalDialog autoSize = newDialog();    
   autoSize.setBodyBorder(false);
    autoSize.setHeadingText("Auto Size Dialog");
    autoSize.setHideOnButtonClick(true);
    autoSize.setWidget(flc);
    autoSize.addButton(new TextButton("Add", new SelectHandler() {
      @Override
      public void onSelect(SelectEvent event) {
        int widgetCount = flc.getWidgetCount();
        StringBuilder s = new StringBuilder(widgetCount);
        for (int i = 0; i < widgetCount; i++) {
          s.append(" *");
        }
        flc.add(new HTML(new Date().toString() + s));
        autoSize.forceLayout();
      }
    }));
    autoSize.addButton(new TextButton("Remove", new SelectHandler() {
      @Override
      public void onSelect(SelectEvent event) {
        int lastWidget = flc.getWidgetCount() - 1;
        if (lastWidget > 0) {
          flc.remove(lastWidget);
          autoSize.forceLayout();
        }
      }
    }));
    autoSize.setPixelSize(-1, -1);
    autoSize.setMinWidth(0);
    autoSize.setMinHeight(0);
    autoSize.setResizable(false);
    autoSize.setShadow(false);

Thank you, that seems to mostly work.

Couple of things:

• The docs for setShadow() say that it defaults to false, however, if I omit that line, the shadow is there.
• setMinWidth() and setMinHeight() say they only apply when resizable is true. So why do we have to set them? Or do the docs need improving?
• The dialog buttons no longer are right aligned for me. I even added the call to align them to the end and still they are left aligned. What is going on there? setButtonAlign(BoxLayoutPack.END);

I'll have to look into the docs and defaults. Although the dialog right alignment for 3.0.6 when autosize is on has an issue and a bug is filed for that.
