How to get button to call a function

Fri Jan 15, 2021 12:31 am
Hi, I am new to KDevelop and Qt Designer. I am using KDevelop 5.5 and Qt Designer 5.12.0 with C++ on Unbuntu Linux. I have a nice interface designed, and the program runs and displays my UI. But there are a couple of things I don't know how to do and I can't find it in any of the documentation or Internet searches. How do I get the press of a button widget to call a function ? How do I programmatically change the text in a line edit widget ? How do I programmatically read the text in a line edit widget ?
