The Interface Design of QT is similar to that of VC.

Pushbutton, radiobutton, and checkbox control

3. Example implementation

Here we use the slot function automatically generated by QT creator, without the need to write the ing between signals and slot functions. (QT creator automatically generates a slot function: Right-click the control → go to slot, and select the corresponding signal function of the slot function, after confirmation, the slot function declaration and definition framework will be generated .)

Figure 3-14 select a signal

Right-click the radiobutton control, select the go to slot option, and select the signal in the signal window, as shown in Figure 3-14. In this example, we use the clicked () signal. After confirmation, it will jump to the definition framework of the slot function. The slot function declaration has been automatically generated, which is similar to winform. Then you only need to fill in the slot function.

Add slots for controls radiobutton_2, radiobutton_3, checkbox, checkbox_2, checkbox_3, btn_radiobutton, and btn_checkbox in the same way.

After the project is created and the corresponding control properties, signals, and slot functions are compiled, edit the corresponding file.
