Columns: selectable with SpanAllColumns & overlaid button does not work

[petrihakkinen]

Please see the attached pic. I would like to overlay a small button on top of a columns view that has a selectable with ImGuiSelectableFlags_SpanAllColumns in the first column but unfortunately it does not seem to work. When I click on one of the 'E' buttons, the selectable underneath steals the mouse press.

I suppose we'd need to add an _AllowOverlapMode. You can also just call SetItemAllowOverlap(), have you tried that?

[petrihakkinen]

Oh, I'm sorry, I did not know about SetItemAllowOverlap() (it was missing from my Lua binding so I suppose it was added by some ImGui update semi-recently). This fixes the issue. Sorry for the noise, and thanks for the quick reply!

Should this issue be closed, or do you want to keep it open for _AllowOverlapMode?

Bit related to this, using ImGuiSelectableFlags_SpanAllColumns cause the columns to not be resizeable anymore. The hover/click done on the Column border is sent to the Selectable instead.

Yes that's known, As stated above, I think calling SetItemAllowOverlap() would fix it. I may look into making that automatic for the column resizing border.

Closing this old issue I forgot to close at the time of adding the ImGuiSelectableFlags_AllowItemOverlap flag shortcut.
