It Ctrl key works correctly here on my Lazarus 1.8.0 64-bit Linux
Gtk2. But Shift key does not work.

Platform?

Here on Windows with trunk it also doesn't work (if I understand the
problem correctly).

With holding CTRL you can select multiple objects in the object
inspector individually (not sequential).

With holding SHIFT you should be able to select a range. Select one
(holding SHIFT) and then select the last (still holding SHIFT).

This last selection process doesn't work in Windows Lazarus trunk.

Rik, can you post a minimal example?

It's in the Object inspector of Lazarus itself (so I can't make an
example).

Open Lazarus with a new project.
But several buttons on a new form.
At the left you see the buttons in the Onject Inspector.
Now SHIFT click the first.
and SHIFT click the last.

As I understand it, all in between should be selected. Is that
correct? Just like in the Windows Explorer?

I haven't got Lazarus 1.6.4 here anymore so I can't check if it worked
there.

I just installed 1.6.4 and indeed, there the SHIFT click works as
expected/described.
I'll look into mantis to see if it's already there and otherwise add
it.

And, O wow. It's not an IDE issue. It's a TTreeView issue.

Create a simple TTreeView in an empty project an add a few items to
it.
Set the tvoAllowMultiSelect in the options to true.

On Lazarus 1.6.4 you could SHIFT click a range and in Lazarus 1.8.0 it
doesn't work anymore.

This is on Windows. Can anybody confirm on other platforms?

Sorry, my mistake. The Ctrl key works correctly on my test but the
Shift key doesn't work on Lazarus 1.8.0 64-bit Linux Gtk2.

Yes, I found the problem.
In Lazarus 1.6.4 and above there is also a MultiSelectStyle in which
msShiftSelect can be set.
But the default is only [msControlSelect].

Lazarus 1.6.4 didn't do anything with that value but from 1.8 onward
it is used.
So you can set [msControlSelect, msShiftSelect] and it works as
expected again.

But Lazarus IDE doesn't set that (and is [msControlSelect] as default.

I'll create a bug-entry for the IDE.

(Note that selecting is different too now. Now with msShiftSelect
items from multiple levels can be selected. In 1.6.4 this was not
possible.)

majid.ebru, if you want to fix this in your 1.8 version you can do the
following.
Open lazarus\components\ideintf\componenttreeview.pasSearch for
tvoAllowMultiselectYou'll find TComponentTreeView.Create()Add the

choose Tools > Build Lazarus with Profile: Normal IDE and click
YesLazarus will rebuild and restartProblem solved
