Here you will find various resources to help you create buttons in Gideros Studio. 

DESKTOPS, MOBILE & HTML5 COMPATIBLE THEY ARE!

note: you may have to provide your own assets (fonts, gfx, …)

Button Button_class

This is the base of all Gideros buttons.


Button Text ButtonText_class

This is almost the same as Button but with some text you can add.


Button Disabled ButtonDisabled_class

This is the same as Button but with a Disabled state.


Button Toggle ButtonToggle_class

A button you can toggle on and off.


Button Monster ButtonMonster_class

This button has a lot: mouse and keyboard navigation, hover, tooltip, sound, ... It may look scary but it is a nice monster ;-)


Button Beast ButtonBeast_class

This is like the Button Monster but without tooltip and without integrated keyboard navigation.
