Information on using Designer can be found in Chapter 26. The figures appear to use a slightly different version of Designer than what's on fenris.
Select Dialog.
Default Dialog Layout.
Open the Display tab and Select TextLabel and click on the Form.
Use the Object Hierarchy to change the names of the Form1 and textLabel1. Resize the label. Size the Form as a .ui file.
Display of screen after creating radio buttons and button group and quit button. Also changing properties.
Click on the connection point to change from arrow mode to connection mode. Drag the quit button onto the form indicating that you want to connect a quit button signal to a form slot.
Add slots to the text label to accept changed in gender.
Create a header and source code using
uic –o frmclickme.h frmclickme.ui
uic –o frmclickme.cpp –impl frmclickme.h frmclickme.ui
These files have a skeleton of the slot, but is not connected.
