qte version is 4.4.3 and qt-extended version is 4.4.3ï¼›
qtopia runs on the computer，and ot transplanted into the development board；
Write an application about printing, can be normal in qteï¼›But compile it in the qt-extended,always prompt QFileDialog undeclared. If we don't use QFileDialog class
,the compile and installation can be normal.But once the application use the Print dialog box will automatically exit. I think qprintdialog class also used qfiledialong class.
1. added the codes "include <QFiledialog>, tips can be found in the header file;
2. I use the example in the qt-extended,add the codes about qfiledialog,tips the qfiledialog is undeclared;
3. I re-compile and install the qtopia, the same results;
That is why?
