Qprogressdialog not updating

(Note that the view will change anyway) Data contain a few types of state.They can for example be individually flagged (in the model) to be draggable and/or be drop targets (see also [2]).A connection is a one-way signal from one QObject to another QObject that does not know an object to know details about the other object. They also work between QThreads, but note they are are always executed in the calling thread. They are connected with e.g.: Note: You probably want to import a lot of classes instead of mentioning Qt Gui and Qt Core all the time.Don't import *, though, it's rather bad style and slow) The basic object you need is a QApplication.QCop Envelope e("QPE/System", "busy()" ) has slightly different behavior: it displays a small hourglass in the task bar.

It seems the DLLs aren't copied, so unless you want to put them with all the apps you make or want to run, you may want to copy the DLLs (in lib) to C:\Windows\System (or system32).The classes: Avoid these *Widgets (and their respective *Widget Items - though note model-view also talks about items of data); they are Qt3-style interfaces provided for easy forwards porting (reimplemented for Qt4-style model-view).They have more decisions than in views and as such are apparently not as flexibly linkable with models, nor as fast. When you want custom behaviour, such as editing table elements, you subclass QItem Delegate (assuming you want some default functions, otherwise you can subclass QAbstract Item Delegate) to create an editable widget on-demand (automatically cleaned by the view).You may want QT's bin path in the path as well, for qmake, but I'm I'm not sure whether it's really necessary.If you want to play around with QT from Python rather than C , that's possible.
