How to connect QPushButton to a group of QPushButton with signal/slot
-
Hi,
I have 9 QPushButton corresponding to the 9 digits 1-9, and I have a board of QPushButton (without text), I would like to connect with signal/slot the 9 digits buttons to my board in order to write the digits on the board's buttons.
So first I created a "normal" project without UI, I placed my buttons and used a QSignalMap to do that and it worked.
But now I would like to do that using the UI but I don't succeed or I could connect all of my 9 digits to all of my board's buttons so would be 9 times 81 (=729) connections which is not sensible, so how can we do something like QSignalMapper with the designer?Thanks.

Why don't you just use the previous non-Ui solution with
QSignalMapperpasting slightly modificated singnal mapping code after you callui->setupUi(this)? Then you will have access to all these buttons and if you bundle yourQPushButtonsin oneQButtonGroup(you can do it from QDesigner - select all buttons, right click and choose something like bundle to a new group - not sure if thats exactly that couse i have designer in my home language but i think you will get it) you can eaisly loop through them to map your signals. -

Yes I can write a QSignalMapper but I wanted to try that with QtDesigner.
Actually I would like to write a digit on the board's buttons but only the selected ones.
So I will try to group the buttons as you said.
