Selecting text with mouse stops when mouse leaves component

[dvhx]

I'm using Lazarus 2.2.0+dfsg1-5ubuntu1 (rev Unversioned directory) FPC 3.2.2 x86_64-linux-gtk2

When I select text, when mouse leaves the component (e.g. Memo or Edit) the selection stops updating. I can only select text with mouse if the cursor stays inside the component. In other apps (eg. leafpad text editor which is not written in lazarus) when I press the mouse and start moving cursor, the selection changes even if I leave the window. How to achieve the same in lazarus apps? It makes selecting text difficult.

TMemo in GTk2 is a native control and you cannot do much here. GTk2 was never my favourite widgetset. You can try to switch to GTk3 but I don't know how mature it is. Selection with mouse out of the control works here (I did a quick test but I have old versions of GTk3 libraries). Qt4 will work for sure but it's a little stranger since whole Ubuntu is GTk based.

Anyway, switching widgeteset can be done in Project Options -> Additions and Overrides; Set "LCLWidgetType".

Is this specific to that one Linux distro (or the exact gtk-2 version)? Or is that the same for all distros?

I have Qt based distro and I can confirm it for GTk2 (2.24). It is fine with GTk3 (3.24). So I guess it is GTk2 specific (not distro specific).
