I am using a DeckPanel to simulate a sprite animation.
The images are runtime specified, so ImageBundles cant be used, and SetURL
is too slow. Flicking over elements in a DeckPanel seems to result in a
smooth animation, however, I am having trouble recieving clicks on the
panel.
DeckPanel itself has no addHandler, so I put it in a FocusPanel.
In doing so I found MouseOver/Out work perfectly...but clickhandleing only
works if its not animating. That is, if the currently shown widget does not
change.
Panel1.setSize("100%","100%");
RootLayoutPanel.get().add(Panel1);
//a deckpanel in a focuspanel test
Image frame1=new Image("Image0.png");
Image frame2=new Image("Image1.png");
Image frame3=new Image("Image2.png");
final DeckPanel deckpaneltest1 = new DeckPanel();
deckpaneltest1.add(frame1);
deckpaneltest1.add(frame2);
deckpaneltest1.add(frame3);
//fix the size again, as deckpanel makes them 100%
frame1.setSize("", "");
frame2.setSize("", "");
frame3.setSize("", "");
deckpaneltest1.showWidget(0);
FocusPanel containerPanel = new FocusPanel();
containerPanel.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//use a random number to see when this is updated
TestLabel1.setText("click recieved."+"___"+Math.random());
}
});
containerPanel.add(deckpaneltest1);
//timer
Timer testanimation = new Timer(){
@Override
public void run() {
int currentw = deckpaneltest1.getVisibleWidget();
currentw++;
if (currentw>=deckpaneltest1.getWidgetCount()){
currentw = 0;
}
deckpaneltest1.showWidget(currentw);
}
};
testanimation.scheduleRepeating(100);
Panel1.add(containerPanel);
Panel1.add(TestLabel1);
My thinking all has something to do with the panel being "focused" which
somehow prevents the normal click events from firing? Or maybe something to
do with the default "focus" css I notice appear on the containerPanel when
clicked. I am not even sure if this is expected behavior or a bug.
In either case, it has me somewhat stuck as to how to proceed.
