1. Problem : After the data appears on QTableWidget, the interface does not respond, does not respond to mouse clicks, but can still normally receive data, can not be closed even close button, the program must be shut down by killing the process. Some computer is unresponsive, some computers they can.
2. Analysis : The reason the interface is not responding:
(1) program crashes stuck, click become unresponsive, but the data is still receiving normal, is not excluded
(2) there has been a modal dialog box on the screen, only to close the modal dialog box before they can click on another interface. And the program can be executed properly. Just interface unresponsive.
3. troubleshooting steps :
View Data window appears in the display, especially the custom window. I added in QTableWidget data, operation column is a customizable widget class, class QTriggerResourceWnd: public QWidget. Then call setCellWidget function to add custom widget window.
QTriggerResourceWnd * pTrgger = new QTriggerResourceWnd();
ui.tableWidget->setCellWidget(step, 8, pTrgger);
By commenting out the line ui.tableWidget-> setCellWidget (step, 8, pTrgger); can be a normal response, it is described QTriggerResourceWnd modal dialog.
So to speak constructor provided by adding a line of code is non-modal: setWindowModality (Qt :: NonModal);
4. Conclusion: due to the system environment, some default Qwidget computer as a modal dialog box, some default Qwidget non-modal dialog box, it is preferably provided setWindowModality (Qt :: NonModal) code; window force set to a non-modal, so that a non-modal windows are displayed in a different system environment, the interface will not be unresponsive.
