Hello, <br>
<br>
As I promised, All the themes in Examples section are working smoothly.<br>
But there is problem in KNewsuff part. It is actually bug of KNewStuff library.<br>
KNewStuff dialog is shown, but I get infinite recursion, when clicked on one tab. <br>
the bactrace shows this.......<br>
<br>
#557 0x410ffe7e in QTabBar::setCurrentIndex () from /home/kde4/qt/lib/libQtGui_debug.so.4<br>
#558 0x405f7f44 in KTabCtl::showTab (this=0x8271cd8, i=1) at qtabbar.h:119<br>

<br>looking into backtrace, the infinite recursion is very clear. After looking into source, the reason is clear...<br>
<snip KTabCtl><br>
void KTabCtl::showTab(int i)<br>
{<br>
unsigned int j;<br>
for (j = 0; j < pages.size(); j++) {<br>
if (j != (unsigned)i) {<br>
pages[j]->hide();<br>
}<br>
}<br>
<br>
if((unsigned)i < pages.size()) {<br>
emit(tabSelected(i));<br>
if( pages.size() >= 2 ) {<br>
pages[i]->raise();<br>
}<br>
tabs->setCurrentTab(i); <span style="font-weight: bold;">// line of interest...</span><br>
pages[i]->setGeometry(getChildRect());<br>
pages[i]->show();<br>
}<br>
}<br>
</snip><br>
<br>
setCurrentTab() calls setCurrentIndex().<br>
setCurrentIndex emits signal QTabBar::selected()<br>
and in the constructor of KTabCtl<br>
<snip><br>
{<br>
tabs = new QTabBar(this);<br>
connect(tabs, SIGNAL(selected(int)), this, SLOT(showTab(int))); <span style="font-weight: bold;">//problematic point</span><br>
tabs->move(2, 1);<br>
<br>
blBorder = true;<br>
}<br>
</snip><br>
The reason of recursion is evident immediately. Corresponding person should resolve this matter.<br>
<br>
I also got a crash when testing themes. That was because of these statements....<br>
function()<br>
{<br>
<br>
QPixmap pm.;<br>
QPainter p;<br>
p.begin(&pm);<br>
bitBlt(&pm,.............................); <span style="font-weight: bold;">//The problem.</span><br>
p.end();<br>
}<br>
<br>
BitBlt actually wants to open QPainter on QPaintdevice, which it cant
do, when it cant do because of p.begin() already called. So there is
trouble and finally crash(qFatal()).<br>
<br>
I just changed the order and everything is smooth. My curiousity is
that, how can this work in Qt3? Does qt allows to call bitBlt() with
opened painter on QPaintDevice?<br>
<br>

As Qt4 port is now complete, I am now doing the bug hunting task. It
looks that perhaps KDE-3.5 branch also had bug, which crashes things.<br>
After some bug hunting When A nice theme is running smoothly, I will post again.<br><br><div><span class="q"><span class="gmail_quote">On 9/1/05, <b class="gmail_sendername">Vinay Khaitan</b> <<a href="mailto:vkhaitan@gmail.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
