ComboBox (DropDownList) and TStringGrid

[7bit]

When I edit a cell (an uneditable drop-down list is shown), I can not set the focus with the mouse on the grid. Why? An example of a project attached.

Lazarus 1.7 (www.getlazarus.org), gtk2 widgetset, Ubuntu 16.04 x64.

It works here on my Ubuntu Mate 16.10 Lazarus 1.6.4 64-bit Gtk2.

On the cell of the first column, press space 2x then the drop down will be shown. Use arrow keys to choose an item and press enter 2x to move to the next cell.

Thanks for the answer! But I want to select another cell not with a keyboard, but with a mouse click. In Windows it works, and in Linux for some reason does not work.

P.S. Excuse me. I'm talking through an online translator.

I did some tests and I can reproduce the issue.

The issue didn't happen if I compile it to produce Win32 executable and run it on my Linux system using Wine. I can use mouse to select items in the drop down and then select other cells.

But if I produce Linux 64-bit binary and run it on my Ubuntu Mate 16.10, I can use mouse to select items in the drop down but then the focus will be trapped in the cell that contains that drop down. I can't select other cells except using keyboard. This Linux test was using Gtk2.

I think this issue is Gtk2 or OS related bug. You may consider to submit a bug report here:
