Slider updating when thumb moves

[SupSuper]

Is there a way to get all the sliders in my UI to redraw whenever the thumb's moved, without having to add code to each of them?
You see, the sliders look like this:

So that whenever the thumb's moved, the glow "follows" it, giving a better idea of its position.

There's nothing for this at the moment, though you could subscribe the global event for a slider position change, extract the source window and manually trigger a redraw. So you'd have to add some code, but not for every slider.

Is this using falagard? If so I think I'll change the slider in there so that moving the thumb position will trigger a redraw of the whole widget. Or, more likely, add a configurable option.

Of course, I forgot about the global event, thanks for the suggestion

And yes it is using Falagard, all my widgets are now, it's awesome

Sorry about double-posting and such, but I've got a problem. I've set up the global event to redraw the slider when changed, only... it doesn't work. It might be because the code is partially made of copy+pasting other existing code on the application since I'm not a very good coder, but it compiles fine:

Code: Select all

CEGUI::GlobalEventSet::getSingleton().subscribeEvent(CEGUI::Slider::EventValueChanged, CEGUI::Event::Subscriber(UITest::Slide,this));

bool UITest::Slide(const CEGUI::EventArgs& e)
{
   CEGUI::Window* slide = ((CEGUI::WindowEventArgs*)&e)->window;
   slide->requestRedraw();

   return true;
}

The global event set required the event string to be prepended with an approperiate event namespace. This is because multiple widget types may define an event with the same name, so we needed a means of identifying the correct event.

So the event to subscribe is:

Code: Select all

Slider::EventNamespace + "/" + Slider::EventValueChanged

Thanks, it works now, though I still got another problem. Look here:

Now, the glow is set as a FrameComponent which tiles vertically and horizontally. So why are the top-middle and bottom-middle parts being stretched?

[CrazyEddie]

As stated in the docs for falagard, the formatting options for FrameComponent affect the background image, they do not affect the egdes of the frame. To tile the edges you need to build the frame yourself using ImageryComponents.
