Description Yuri Timenkov 2007-12-01 14:00:26 UTC
Version:           3.96.00 (using KDE KDE 3.96.0)
Installed from:    Ubuntu Packages
OS:                Linux

When I open third RDP connection, the third and second screens are displayed on the same tab, and third one is empty.
I use:
rdesktop: A Remote Desktop Protocol client.
Version 1.5.0. Copyright (C) 1999-2005 Matt Chapman.
This issue appeared on the first SVN builds of krdc when tabbed interface was announced (And I periodically build KDE from SVN in hope that this bug will be fixed, because this tabbed interface is incredible!)
I open most of connections in 1024x768x16 resolution, but I have 3-head Xinerama configuration, may be problem is here, but As I remember in Xephyr session this bug appeared too.
See attached screenshot.

Screenshot with misplaced views

mccp5 tab (first) is displayed properly,
second tab (mccp1) is empty.
And connections from second and third tabs are both displayed on third tab.

Can you please start KRDC from Konsole, so that you can paste the whole debug output? I think that could help me. Just be sure that you do not paste any sensitive data (e.g. passwords) here. Thanks.

KRDC console output

Today I checked out KDE svn from trunk. bug still exists.
I noticed that misplacement occurs then new (third) tab is allocated (the RDP
view from second tab moves to new one) and preferences dialog is shown.
Also, i use mainstream qt from gutsy, instead of qt-kdecopy, if it will help.
Comment 4 Yuri Timenkov 2007-12-03 16:08:53 UTC
I suppose I found where bug:
svn diff -r 684033 mainwindow.cpp

-    scrollArea->setWidget(m_remoteViewList.at(m_tabWidget->count()));
+    scrollArea->setWidget(m_remoteViewList.at(m_tabWidget->count() - m_showStartPage ? 1 : 0));

The hack solution is to replace to
    scrollArea->setWidget(m_remoteViewList.at(m_tabWidget->count() - m_showStartPage));

And this works (Assuming (int)true == 1), but it is better to rewrite condition or even generalize dependency on m_showStartPage, because there are many places like: int i = m_showStartPage ? 1 : 0;

But it is not time to refactor code :(

SVN commit 744478 by uwolfer:

Fix: KRDC with more than two open tabs works now too.
Thanks Yuri Timenkov for pointing in the right direction. Please verify if that fixes the problem for you. Thanks!
