Ternary Operator Toggle

4 posts in this topic

I have done this before but I can't track down my code that did it. I'm trying to make a function that will toggle visibility based on a radio button and I'm getting an error:

Statement cannot be just an expression.

This is my function:

Func ToggleVisible($ctrlName)
    GUICtrlRead($ctrlName) = 1 ? GuiCtrlSetState($ctrlName,$GUI_SHOW) : GuiCtrlSetState($ctrlName,$GUI_HIDE)
EndFunc

What am I doing wrong?

Have a look at this link. After adding an assignment to the statement it worked like a charm.

Don't you need GUICtrlGetState()?

Also try and limit your scope with ternary e.g.

Func ToggleVisible($idControl)
    GUICtrlSetState($idControl, (GUICtrlGetState($idControl) == 'SOMETHING') ? $GUI_SHOW : $GUI_HIDE)
EndFunc

The same can be said for that post @MikahS mentioned

Ahhh that makes more sense... This is what it ended up being:

Func ToggleVisible($idControl,$idToggle)
    GUICtrlSetState($idToggle, (GUICtrlRead($idControl) == 1) ? $GUI_SHOW : $GUI_HIDE)
EndFunc
