[Nifty] Disabling a button --Delayed

Troubleshooting gui
1

Hello,



I’m trying to disable a button on certain conditions in one of my GUI.



At first I tried :

[java]

element = screen.findElementByName( “btnNewGame” );

element.disable()

[/java]



Problem :

My button is still intercepting Mouse focus.



So I tried :

[java]

element = screen.findElementByName( “btnNewGame” );

element.startEffect(EffectEventId.onCustom);

element.setFocusable( false );

element.setVisibleToMouseEvents( false );

[/java]

With a effect OnCutom :

[xml]

<onCustom name=“fade” start="#ff" end="#30" neverStopRendering=“true” />

[/xml]



It looks great but …

I still have a problem with focus :



My button “btnNewGame” has the focus by default. So when I call the method

[java]

element.setVisibleToMouseEvents( false );

[/java]

The button is still with the focused appearance and It doesn’t disappear.



I tried

[java]

//Give the focus to the End / Continue button

Element element = screen.findElementByName( “btnEnd” );

element.setFocus();



//Invalidate the new Game button

element = screen.findElementByName( “btnNewGame” );

element.startEffect(EffectEventId.onCustom);

element.setFocusable( false );

element.setVisibleToMouseEvents( false );

[/java]

But it the button “btnNewGame” remains with the focused appearance.



Do I need to delay the setVisibleToMouseEvents call ?



Thanks in advance.

you need to delay the use of this until nifty 1.3 is released :slight_smile:



unfortunatly enable/disable support in nifty 1.2 is quite rudimental. there already exists a feature request (with patches by tumani!) for this in the feature tracker at sf.net https://sourceforge.net/tracker/?func=detail&aid=3035579&group_id=223898&atid=1059825.



so, you’ve done everything correct and the situation will improve with 1.3.



in the meantime you should be able to call removeFromFocusHandler() on the element to remove the focus.
