General and Desktop

I have merged your two topics into one.

And remember that a slot is a normal C++ function (member function). Therefore you can perform any action in your slot. For your example, it will give : @ void MyClass::onMyButtonClicked() { myLabel->setText(myLineEdit->text()); } @ And btw, welcome and have fun with Qt :)

thank you , MR 2 , I have tested it with the small program , but didn't find any strange result . So thank you again , Mr 2 , just ignore this .

Hi Gerolf, I think i found the problem let me solve and let you know. problem was with ---model.removeRows(0,item.rowCount(),index) solution -- item.removeRows(0,item.rowCount()) thanks

Fonts are not part of Qt though, so what is your question then exactly?

bq. I wonder if item transformations can screw up the painting. whit that code the image grabbed will be the item without transformations. But if you inscribe your item into another, you can then grab the outer one with the inner rotated :) bq. @deimos: your mediadownloader is a nice piece of software ! Are you playing the videos natively using FFMPEG and QPixmap(s) ? thanks a lot. Compliments are always welcome and I didn't received a lot even if it is been downloaded a lot :) Video are played with phonon (I am rewriting it using QtMultimediaKit without phonon) and since youtube needs cookies and with phonon you have not direct access to network (you can't set QNetworkRequest) I have subclassed QIODevice to threat streaming videos as a local file. They can be played also with mplayer. FFMPEG is used only to convert them. sorry to all for this OT @bunjee: if you want to find me I am in #qt, #meego channels at freenode irc :)

Exactly what I was looking for! Many thanks for the suggestions.

Just realized that it probably isn't working because I'm running ubuntu as the guest OS on VMware and I see a lot of posts related to absence of 3d h/w acceleration on a VM. Works just fine on my laptop that runs ubuntu. I also realize it isn't a Qt question (anymore) but any inputs on how to get it to work on a VM would still be useful.

yes, i did everything... now this error is solved. thank you! =)

If your model only uses a QSqlRelationalTableModel, then I suggest you don't inherit from it, but instead use encapsulation. That is: your model has a QSqlrelationalTableModel, but is just a QAbstractItemModel. There is little we can say on why this happens, if you do not show us any relevant code.

So..., Nobody has any idea of what this 'Phenomenon' is all about??

I found a solution for my problem by looking again at the "Star Delegate Example":http://doc.qt.nokia.com/latest/itemviews-stardelegate.html. Instead of calling render(...) with option.rect.topLeft() as offset, translating painter with option.rect.topLeft() before calling render(...) fixes my problem: @ list_widget.render(painter, option.rect.topLeft()); @ @ painter->translate(option.rect.topLeft()); list_widget.render(painter); @ So apparently I didn't understand what the effect of calling "QWidget::render(...) with a targetOffset":http://doc.qt.nokia.com/latest/qwidget.html#render-2 means. Thanks again for all your input.

I tried with pallet, and for me also it failed. May be we should look for some other work around to appear the same,like its mentioned in stack overflow.

Hi there, lots of questions, huh? I believe there is an error, because your QPaintEngine will never match your condition. Here I had problems because I have OpenGL2 and was comparing only OpenGL. Maybe if you replace && by ||. @if (painter->paintEngine()->type() != QPaintEngine::OpenGL || painter->paintEngine()->type() != QPaintEngine::OpenGL2)@ This path is difficult [quote author="basil_fawlty" date="1314306305"] I thought that it might be possible to integrate my own GLWidget, where i define the typical QGLWidget/OpenGL-Functions.I @ void initializeGL(); void paintGL(); void resizeGL(int width, int height);) @ Somehow like this: @ GraphicsView view; view.setViewport(new MyGLWidget(QGLFormat(QGL::SampleBuffers))); @ But it isnt working. [/quote] Well, there is an example code you can use on the same "link":http://qt.gitorious.org/qt-labs/modelviewer you have pointed. It might be enlightening to you. As the whys of this strategy, I honestly don't know. I hope this helps, Regards, VitorAMJ

Thanks a lot to you all. It was a great help.. Truely very much thanks. :)

Hi, Thanks for the reply. I realized the mistake am doing. Thanks again. -Karthik

"QNetworkAccessManager::head() ":http://doc.qt.nokia.com/4.7/qnetworkaccessmanager.html#head is your friend. Use it just like a get request.

Thanks, Gerolf. I notice my mistake now.

[quote author="mlong" date="1314403576"]I'm not sure what the behavior of a QDockWidget is if it's not used in conjunction with a QMainWindow. According to the docs, a QDockWidget is designed to be docked in a QMainWindow, not just an arbitrary widget. You can always create a QMainWidget, and set your AdvancedTextEditor as its central widget. Then the dock widget should behave properly. [/quote] Thanks for all the help, =). Solved !! =)..
