how to set open to null in java? #144

Closed gurachan closed 3 years ago

gurachan commented 3 years ago 
boolean[] open = new boolean[]{false};
imgui.begin("Hello", open, 0);

in kotlin its fine to set it as null but in java .. it says ambiguous and crashing. it seems i can only set boolean ..

if I force it on runtime tho 

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method imgui.ImGui.begin, parameter pOpen

I just want to disable the close button. i get the idea of the closing on this

Use fun begin(name: String, pOpen: BooleanArray?, index: Int, flags: WindowFlags) by calling it as

begin(name, close, 0, flags)

ow thanks it works

imgui.begin("test", null,0, WindowFlag.AlwaysAutoResize.i + WindowFlag.NoResize.i)

i dint know theres another begin one

It's not the best in terms of elegance, but it's the best compromise I could have found

If you have a better idea don't hesitate
