gwt dialogbox won't move - gwt

Question

i created a dialog box using uiBinder in gwt app, it works fine except it cannot move around. i don't know what's wrong with it, do i have to set caption in order to move it around?
here is my code:
myDialog.ui.xml
<g:HTMLPanel ui:field="_glossaryPanel">
<div class="dialogBox">
<h3>content goes here..</h3>
<p>More content...</p>
</div>
</g:HTMLPanel>
myDialog.java
public class MyDialog extends DialogBox {
private static MyDialogUiBinder uiBinder = GWT.create(MyDialogUiBinder.class);
interface MyDialogUiBinder extends UiBinder<Widget, MyDialog> {
}
public MyDialog() {
setWidget(uiBinder.createAndBindUi(this));
this.setModal(true);
this.setAutoHideEnabled(true);
}
FooterView.java
public class FooterView extends Composite implements FooterPresenter.Display {
interface Binder extends UiBinder<Widget, FooterView> {
}
private static final Binder BINDER = GWT.create(Binder.class);
#UiField
Anchor _glossary;
#UiHandler("_glossary")
public void handleGlossaryClick(ClickEvent event) {
MyDialog mDialog = new MyDialog();
mDialog.setGlassEnabled(true);
mDialog.setAnimationEnabled(true);
mDialog.center();
mDialog.show();
}

Answer 1

See http://gwt.google.com/samples/Showcase/Showcase.html#!CwDialogBox You have to use a DialogBox (not a PopupPanel) to move the thing around.
EDIT:
I tried your code and it worked for me. Have you tried clicking in the border (not content!) to drag the dialog box around?

Answer 2

GWT Dialogs can't be moved around like a desktop window. There was a projected called gwt-windows that would let you do that, but it hasn't been updated in years.

Answer 3

Maybe you could try in your ui.xml file to change the root element type
from HTMLpanel to a FlowPanel
I saw somewhere that was saying something like this. where ? I can't remember :-(
your <div clas="dialogBox"> is, in my opinion, a bit confusing, maybe yould consider renaming to something more personal and less in gwt keywords' like.

Here is the Solution,
VerticalPanel panel;
DialogBox dialogbox;
PopupPanel glass;
VerticalPanel DialogBoxContents;
ClickListener listener;
HTML message;
Button button;
SimplePanel holder;
public void demo()
{
// Create a panel and add it to the screen
panel = new VerticalPanel();
RootPanel.get("demo").add(panel);
panel.setStyleName("table-center");
//
// Create a DialogBox with a button to close it
dialogbox = new DialogBox(false);
dialogbox.setStyleName("demo-DialogBox");
DialogBoxContents = new VerticalPanel();
dialogbox.setText("DialogBox");
message = new HTML("Click 'Close' to close");
message.setStyleName("demo-DialogBox-message");
listener = new ClickListener()
{
public void onClick(Widget sender)
{
dialogbox.hide();
}
};
button = new Button("Close", listener);
holder = new SimplePanel();
holder.add(button);
holder.setStyleName("demo-DialogBox-footer");
DialogBoxContents.add(message);
DialogBoxContents.add(holder);
dialogbox.setWidget(DialogBoxContents);
//
// Add a button to the demo to show the above DialogBox
listener = new ClickListener()
{
public void onClick(Widget sender)
{
dialogbox.center();
}
};
button = new Button("Show DialogBox", listener);
panel.add(button);
}

"do i have to set caption in order to move it around?"
Yes.
dialogbox.setText("DialogBox");
You may drag only catpion div;
When you drag caption div, whole dialog box will move.
