Platform: Using GWT1.5 (release) and linux
When I have a single instance of a popup panel, and it has it's
content & position set in response to rollover of multiple elements,
all works fine until I enable animation.
To run the test case just use
yourWidget.add(PopupFail.buildFailingTestCase()) to see the error.
Is there any way to get around this?
package com.google.gwt.user.client.ui;
import com.google.gwt.user.client.DOM;
public class PopupFail {
public static Widget buildFailingTestCase() {
VerticalPanel p = new VerticalPanel();
p.setSpacing(5);
p
.add(new Label(
"Run your mouse quickly over
the fail labels to see animation
causing fail."));
PopupPanel pop = new PopupPanel(true, false);
pop.setWidget(new Label("FAIL!"));
pop.setAnimationEnabled(true);
p.add(new Invoker("Fail 1", pop));
p.add(new Invoker("Fail 2", pop));
p.add(new Invoker("Fail 3", pop));
p.add(new Invoker("Fail 4", pop));
p
.add(new Label(
"Run your mouse quickly over
the pass labels to see no animation
causing win."));
pop = new PopupPanel(true, false);
pop.setWidget(new Label("WIN!"));
pop.setAnimationEnabled(false);
p.add(new Invoker("Pass 1", pop));
p.add(new Invoker("Pass 2", pop));
p.add(new Invoker("Pass 3", pop));
p.add(new Invoker("Pass 4", pop));
return p;
}
static class Invoker extends Label implements MouseListener {
PopupPanel pop;
public Invoker(final String text, final PopupPanel pop) {
super();
this.pop = pop;
addMouseListener(this);
setText(text);
}
private int getDisplayLocationX(final Widget sender, final int
x) {
return sender.getAbsoluteLeft() + x +
getPageScrollLeft();
}
private int getDisplayLocationY(final Widget sender, final int
y) {
return sender.getAbsoluteTop() + y + getPageScrollTop();
}
private int getPageScrollTop() {
return DOM
.getAbsoluteTop(DOM.getParent(RootPanel.getBodyElement()));
}
private int getPageScrollLeft() {
return DOM.getAbsoluteLeft(DOM
.getParent(RootPanel.getBodyElement()));
}
public void onMouseDown(final Widget sender, final int x, final
int
y) {
}
public void onMouseEnter(final Widget sender) {
pop.show();
}
public void onMouseLeave(final Widget sender) {
pop.hide();
}
public void onMouseMove(final Widget sender, final int x, final
int
y) {
pop.setPopupPosition(getDisplayLocationX(this, x),
getDisplayLocationY(this, y));
}
public void onMouseUp(final Widget sender, final int x, final
int y)
{
}
}
}
