[SOLVED] Three-state (tristate/indeterminate) checkbox in tray menu?

[VAN0]

Hello.

Is there a way create a menu item in tray menu that would show as 3 state checkbox (indeterminate)?

(I already have the functionality of 3nd state, just can't make it show visually)

 

Thank you.

I found a way by replacing type of menu item to radio for the indeterminate state, and switching back to checkbox for any other states:

$val = 0 ; 0 = unchecked, 1 = checked, 2 = indeterminate
$tMenuItem = TrayCreateItem("Test tray menu item")
$type = 0 ; checkbox
$checked = $TRAY_UNCHECKED
If $val > 0 Then
    $checked = $TRAY_CHECKED
    If $val == 2 Then $type = $MFT_RADIOCHECK ;512 = radio
EndIf
_GUICtrlMenu_SetItemType(TrayItemGetHandle(0), $tMenuItem, $type, false)
TrayItemSetState($tMenuItem, $checked)
