QT version 5.1
I have 2 issues:
1) I am wondering is there is any way I can set QLineEdit widget to accept only integer in the range from 0 < x < 255 from QT DESIGNER. I guess Input Mask can do this thing for us but wondering how ?
2) Only if we can't set values from QT designer, then in that case I have to do it from the source code. For that in which files will i make the changes?
Below is brief description of my project:
i) I have designed a GUI on QT designer with lots of QLineEdit widgets and buttons, checkbox etc.
ii) I am aware that there is QValidator class exist which can solve my problem . I know how to use QValidator but wondering just in case if I can't set validation of QLineEdit from Gui then I have to do it from source code. This is not a problem but where will I add my validation code in source code?
Should I add this in the constructor of GUI?
