|Summary||0015245: Grouping menu items as RadioItems doesn't work in main menu|
|Description||I create a menu and give each item following properties:|
- AutoCheck = True
- RadioItem = True
- GroupIndex = 1
This should only allow checking one item within a group. It works as intended if used in TPopupMenu, however it doesn't work in TMainMenu.
I checked this on Linux/QT.
In Linux/GTK2 and Win32 widgetsets it works as intended.
Also, there is one inconsistency I found between GTK2 and QT in TPopupMenu. On GTK2 after the program starts the first item of a group is already automatically checked. This is not happening in QT. I haven't checked how it works on Win32.
Sample program is attached.

qt_radioitem.tar.bz2 (1,602 bytes)
BTW in Delphi 0 is the valid group index.
In LCL I have to set GroupIndex >0 to make grouping work.
This bug is because we have not QActionGroup in our C bindings yet.
QActionGroup can set exclusive mode (and show RadioItems instead of CheckBoxItems).
I'll ask Den if he can add it to bindings, or I have to find another approach to fix this problem.
In win32 1-st item in menu is not automatically checked.
In gtk2 both menus on startup have 1-st item checked.
||In qt too (but C++) when we use QActionGroup, which is unavailable currently in our bindings.I've sent message to Den to include missing class.|
Ok, this almost finished (but not commited yet, since I must wait until Den prepare 1.73 bindings from 1.73RC).
I'm just wondering what todo with those widgetset diffs like Anton Kavalenka mentioned.
Should we check always first radio item if there's no checked items, or leave it as it is on windows (win32) ?
The same inconsistency is with normal radio buttons:
- on Win32, QT first button is not checked
- on GTK2 first button is checked
On GTK2 setting Checked=False for all radio buttons in a group is not possible, but it is allowed on Win32 and QT (unless using TRadioGroup). This might be a GTK2 behaviour that it doesn't allow a group without an item selected.
I propose that menu radio items are done the same way as radio buttons - the first item is not automatically selected, unless specifically Checked=True is set for this item.
||ok, then I'll do it in that way, but what's the meaning of Default property in TMenuItem ?|
||I think Default means the item should displayed distinctively from other items (for example in bold font). But it doesn't seem to do anything in GTK2 or QT. It is probably used with popup menus, when a default action on an object should be highlighted.|
||Test and close if ok.|
||Thanks. Works like a charm.|
