LibGDX: Leave all Actors on stage unchecked
I have a stage with multiple buttons on it, basically used as a toolbox. I want the user to be able to choose between the different items displayed; Therefore, when the user selects an item, all other items must be deselected.
I want to do this with the checked attribute of the libGDX button. However, I don’t know how to programmatically uncheck the button and access all the Actors on the Stage in the simplest way.
can’t provide the code because, as I said, I don’t even know how to uncheck the button, and Google doesn’t help. Is this possible? If not, I’m happy to take other suggestions.
Take a look at ButtonGroup
ButtonGroup is not an actor and has no visuals. Buttons are added to it and it enforce a minimum and maximum number of checked buttons. This allows for buttons (button, text button, checkbox, etc) to be used as “radio” buttons. https://github.com/libgdx/libgdx/wiki/Scene2d.ui#wiki-ButtonGroup
Also try to see useful javadocs http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/scenes/scene2d/ui/ButtonGroup.html
Basically, you create a ButtonGroup to add actors and set the minimum amount of checks that should be allowed.
//initalize stage and all your buttons ButtonGroup buttonGroup = new ButtonGroup(button1, button2, button3, etc...) next set the max and min amount to be checked buttonGroup.setMaxCheckCount(1); buttonGroup.setMinCheckCount(0); it may be useful to use this method: buttonGroup.setUncheckLast(true); If true, when the maximum number of buttons are checked and an additional button is checked, the last button to be checked is unchecked so that the maximum is not exceeded.
