I am currently trying to apply an overlay with LibGDX over my 3D ModelBatch. Everything works fine except for the SelectBox. Once instanciated, it shows up on my screen I can click on it once but then it freezes. The drop-down list is not displayed and the clicks are no longer registered by my application. However, if my second click is under the standard position of the list, that is where it should be drawn when it drops down, an item is selected but then any third click will just return the list to the original selected item and no click is registered by my application anymore. I am running the application on Desktop.

Using break points in the SelectBox.class I was able to notice that the third and other next clicks are registered by the SelectBox.class as part of the list in the Listener responsible for selecting an item.

selectBox = new SelectBox<Object>(skin);        

array in this case is an instance of Object[] containing only Strings. This is the only part of code I have related to the selectBox.

I have tried using an array of String[] at first but then switched to Object as suggested on a LibGDX forum.

I am currently using the latest Nightly Build of 2014/04/11 as I also need TextArea which is not yet in the stable release. However, I have tried the stable release 0.9.9 and it doesn't work either.

Am I using the right code to declare my SelectBox, or what could I do to make the SelectBox behave properly that is display its list when clicked and return to a normal state after an item is selected?

Just had a similar problem. The following code in the render method of the screen helped:

stage.act(Math.min(Gdx.graphics.getDeltaTime(), 1 / 30f));

  • \$\begingroup\$ This is unlikely to solve the problem, since not calling the method would not result in a crash. Also, you don't need to call it with arguments, stage.act(); would suffice. \$\endgroup\$ Commented May 14, 2015 at 1:25
