           Summary: [CameraUI] Focus steal when typing custom prefix in
                    renaming options sidebar
           Product: digikam
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Camera GUI
        AssignedTo: digikam-devel kde org
        ReportedBy: sebastian.roeder uni-bielefeld de


Version:           0.9 SVN (using KDE KDE 3.5.2)
Installed from:    Gentoo Packages

Since half a week or so I encouter the following problem when I want to download pictures from my Nikon D70 (PTP) with digikam SVN trunk:

In the settings sidebar when I want to type in a custom prefix in the textbox I can only type 1-2 letters befor the textbox looses the focus. I have to activate the textbox again by left mouse click and can type 1-2 letters again, focus loss again and so on and so on.

Sorry I have no time to examine the code atm cause real life is very hard (yeah I know that sounds lame ...). The problem didn't go away in latest SVN. Maybe it's related to a Qt update I did recently (from 3.3.4 to 3.3.6) but otherwise I would say nothing changed in my system.

Regards,
Sebastian

I cannot reproduce this problem in my system. Are you use a Gphoto2 camera or UMS camera ?

Hi Gilles,

> I cannot reproduce this problem in my system. Are you use a Gphoto2
> camera or UMS camera ?

Hmmm, I did a little further testing and the behaviour exists for both PTP
Mode (gphoto2) and Mass Storage. I also tested whether the autorotation or
photographer/copyright settings have an impact on that behaviour and the
answer is "no" for both.

However the problem seems not to be so hard then yesterday - in most
situations I have enough time to type in the name I want. This brings me to
the question whether this is a "feature" and not a bug - do you want the
cursor to jump to the last selected image after some seconds of no user input
in the text box (that is what actually happens)? The focus stays intact in
the textbox when a) the textbox is empty or b) the text in the box is
selected.

I hope this information is usefull in some way. I notice a "refresh" of the
cameraui window everytime this focus change appears (the whole
window "blinks" once). It looks to me like some kind of polling is active?

What else can I test? Recompile with full debug? Recompile with Qt 3.3.4
rather then 3.3.6?

I tested this problem again on latest SVN with diffrent cameras:

Nikon D70 both in PTP mode and in USB Mass Storage mode
Canon A75 in PTP mode

The problem is still there and I find it very annoying. Also the atempts to fix the problem by myself failed cause I didn't quite get the qtimer thingy yet.

Doesn't anybody else have this problem? Is this only me? Would be great if someone could reproduce the flicker and report back.

You could add debug statements to all the "d->changedTimer->start" lines in renamecustomizer.cpp and a statement to the "CameraIconView::slotDownloadNameChanged()" method in cameraiconview.cpp, which is called by the timer signal. Check if the latter method correlates with the flicker you are experiencing. Then, I still don't know why the focus would be lost.

Seb,

The problem is fixed in my computer. Look in B.K.O #131034 : there is a patch to improve camera gui. I have include this fix in this patch.

Apply the patch against current svn implementation and give me a report.

Gilles
