General and Desktop

MSDN is a good starting point: http://msdn.microsoft.com/en-us/library/windows/desktop/ms645536(v=vs.85).aspx In "using raw input", there are a few examples.

Thanks, that suggestion worked well. Here's a code sample in case anyone else wants to do something similar: @class custom_table(QtGui.QTableWidget): def __init__(self, parent=None): QtGui.QTableWidget.__init__(self, parent) self.chkbox1 = QtGui.QCheckBox(self.horizontalHeader()) def resizeEvent(self, event=None): super().resizeEvent(event) self.chkbox1.setGeometry(QtCore.QRect((self.columnWidth(0)/2), 2, 16, 17))@ The "(self.columnWidth(0)/2)" keeps the checkbox in the middle of the column header.

exactly what i was looking for, even lets you do multiple colors! and unfortunately google was of no help with pointing me to this gold mine. Thanks!

Right, well thank you. my problem is solved! Much appreciated.

Glad you were able to find a solution! Please edit your title post and add [Solved]. Thanks!

Thanks! Your short list is a better documentation than anything I have found so far. "qws" sounds promising, maybe this is exactly what I need.

See "here.":http://qt-project.org/doc/qt-4.8/stylesheet-examples.html#customizing-qradiobutton

If you use a file you might want to use this: sendProgress->setValue( (fileToSend->pos() * 100) / fileToSend->size()); The pos() functions comes from the QIODevice class, but it is inherited by QFile.

bq. I guess you have checked already some ms fora for a solution? Well I checked stackoverflow.com. So if you are debugging on a Mac or Linux with gdb and type bt you will get always a useful stack trace? I have to point out, that in my case we develop extensions for an already existing application. Qt and the extension are loaded via dll into another program. Because of this I think the call stack is even larger, than it would be for a "normal" Qt app.

QSignalMapper is used to combine multiple signals from different widgets into one signal, for example if you want to change the text of a label from the values of multiple combo boxes. If you just want to set the label to the value of a combo box use the currentIndexChanged signal instead. @ connect(comboBox, SIGNAL(currentIndexChanged(QString)), label, SLOT(setText(QString))); @ In addition to the documentation you might read "this article":http://doc.trolltech.com/qq/qq10-signalmapper.html featuring the purpose and usage of QSignalMapper.

You could try changing the permission on a directory to see if I'm right but I'm quite sure that this is the expected behavior.

What do you gain, if you method is fast, but wrong? Nothing than pain in the future! Premature optimization is the cause of many evil! Make your method work correctly first, and then do optimizations and only if you run into performance issues! ++r or r++ is negligible in that case. Ask Google for the myriads of performance discussions on this topic please.

There are various ways - depending on the design of your application. The obvious one is passing the label to TextController in the constructor, using a setter or a combination of both. @ class TextController { public: TextController(QLabel *label) : label_(label) { } void setLabel(QLabel *label) { label_ = label; } QLabel *label() const { return label_; } void Print() { if(label_ != 0) { cout << label->text().toStdString(); } } private: QLabel *label_; } .... TextController myTextController(myLabel); .... myTextController.setLabel(myLabel); @

You can create a custom widget with desired text/progress bar etc, and add a thread to process, or process without a thread ( OS will treat program as not responding, if there is a lot to process). Hope it helped. Regards, Jake
