Re: [Interest] how to debug a Qt Designer plugin

Hi Graham, It could be several things: - the plugin has been compiled with debug - it must be release build. - supporting DLLs are not available in your path. - the code in the plugin is relying on initialisation that only occurs in your main exe. Because of the first point, you

Re: [Interest] Threading Question

Hi Jason, Are you calling QApplication.exec in your main thread? In not, I don't think the slots there will be activated. Regards, Tony -Original Message- From: interest-bounces+tony=rightsoft.com...@qt-project.org [mailto:interest-bounces+tony=rightsoft.com...@qt-project.org]

Re: [Interest] Custom layouts

Hi Igor, Your problem makes sense. Hiding and showing widgets triggers a layout recalculation, and the layout uses setGeometry to position the widgets. It sounds unusual to change widget visibility in a setGeometry override. I suggest to use a flag to prevent the recursion yourself.

Re: [Interest] Issue with stylesheet and palette()

Hi Max, In our Qt 4.8.6 app we use the Polish event to apply changes after the styles are set in our base window class: bool BaseForm::event(QEvent *event) { bool result = QDialog::event( event ); if (event-type() == QEvent::Polish) {

Re: [Interest] Qt Plugin Low Level API

Hi Etienne, The 4.8.5 doco for QObject.qobject_cast links to the Plug Paint example for use of qobject_cast with interfaces. Mind you, it incorrectly shows the return type as QWidget. Hopefully that doco has been rewritten in v5! Hope that helps, Tony From:

Re: [Interest] Is there any way to find QML object by id?

Thats exactly what I would also do if it would be my component, but unfortunately I don't have an access to TextInput { id: input } which is inside the ComboBox. But you are able to assign the ID or is it built-in? I don't get the problem, although I have not used the ComboBox, so maybe
