Hi,

I have a suggestion to the Alt key for column section. Currently it doesn't work at all on Linux and probably *BSD too. The problem is two fold.

1) This is because the Alt+Click+Drag is already used by X11 to move windows around (without doing in from the title bar).

2) Even though the description of that feature says Alt key, Lazarus actually means "Left Alt" key only.

What if Lazarus changes that option to use the Right Alt key instead. Currently this is not used by X11, and seeing that Lazarus seem to differentiate between Left Alt and Right Alt anyway, this could be a solution that could work on all platforms?

Well, it'd better change to use any Alt then? Or be configurable? And add shortcuts to change or toggle the SelectionMode? ;-)

I haven't checked it under Linux. But on windows, the right alt key, simply translate into ctrl-alt. You can test it using shift-alt and cursor keys for selection

That means on windows, using the mouse I can use either alt key (because ctrl+alt does not activate the mouse links)

This is weird, I could swear AltGr was working here, but it isn't. And here (Win7, Brazilian kbd, CapsLockBeGone=Shift) it doesn't detect ssCtrl either.

Adding support for ssAltGr is as simple as adding in lcl\forms.pp, line 1764:

+  if GetKeyState(VK_RMENU) < 0 then Include(Result, ssAltGr);

Should we also support an independent left Alt state and leave ssAlt to mean any Alt? What about the other keys?

Best regards,

All good and well, but I was actually referring to SynEdit (Lazarus's editor component), not a Form.

Does that work on all widgetsets?

And what about people relying on the current behaviour, where AltGr does map to alt-ctrl? Currently (nmopt sure if mapped by the lcl, or if send by windows) an application receives alt-ctrl, for AltGr. existing apps may rely on that

For example, on Windows (tested with windows, but I remember this was already true in the early days), using a german keymap (where altgr is used.

AltGr - Q is @, and you can use ctrl-alt-Q as well. There are several other such examples on the german keymap. And I believe there are other none english keymaps that work similar too.

I don't know how those work on Linux.
I don't know about Mac (does Mac have altgr?)

And none windows systems obviously could also use the "windows" key as modifier.
Actually, even on windows, you can have an app that uses the windows key....

SynEdit just looks at what it gets from the LCL, and what it is configured to do.

If you use a windows manager that steels away a key or mouse combination, then that is not synedits fault [1].
If synEdit never receives the alt-left mouse, that is your window manager.

The IDE has an advanced mouse setup, it can be changed there. So has your window manager.
