Core using a custom widget.....

Hi...i'm new using QT and this could be a silly question.....

I created a widget using the assistand example, the timeclock, but only using a widget created with the designer, i have ui_my_widget.h, an my_widget inherit class and another class which uses the "QDesignerCustomWidgetInterface", and finally a .pro with the same estructure that the clock example. I do a "make install" and the designer finds it, but when a drag the widget on the form the designer crash........

Someone Knows why this happend? or some tutorial step-by-step to add widget to the designer??

Thanks..

I think this is what you are looking for

Yes , i readed the Qt documentation, and following the steps as the example says, but it crashes anyway........

if someone creates a widget and it works i will appreciate some basic steps to create my own, because i don't know what the is the problem......

even the core file have not symbols about the crash, my widget is compilled in debug mode....

My steps where:

1- create an "UI" with the designer, result a ui_my_widget.h
2- create an inherit class my_widget.h from the previous ui.h using the QDESIGNER_WIDGET_EXPORT macro in the class definition as the example says.
3- create another class inherint from QDesignerCustomWidgetInterface, with a new of may widget in the "createWidget" method and the Q_EXPORT_PLUGIN2 macro at the end of the file.
4- create a .pro with the proper plugin and lib parameters and do a "make install", the paths and files are correctly created into the QT paths.
5- The plugin appears in the designer but when i clicked over it there is only a blank box with the size of the XML method from the QDesignerCustomWidgetInterface inherit class.
6- finally when i drag and drop the widget over a frame the designer crashes

Maybe some step is wrong .....

Some help on compilation or other example custom plugin will be great...

Thanks....

I'd say you have an uninitialized pointer somewhere. Your plugin is fine if the widget shows up in Designer.
