"Don't show this meesage again" checkbox in QMessagebox

[SGaist]

Hi,

The logic has already been explained several times:

1. Get the settings value
2. Check what that value is
3. Show or not the message box based on this value
4. If the message box has been show, update the settings value

In any case, you really should use more meaningful variable and key names. It would help you quite a lot with the code flow.

@SGaist That is what my question is actually. The logic is understood, but the 3rd point u have mentioned is the actual problem. How to use this value to not show the pop-up. That is what I want to know.

The third point is a simple if () statement checking the value of the setting...

[Prathamesh]

@jsulm Of course it is if statement, my question was not about how to check the value. My question was how to use that value to show message-box or not to show it. I hope this time it is clear.

@Prathamesh

How you would do it without QSettings? Same thing. Doesn't matter where the bool is coming from. Set it somewhere (member / class var) and then put the check before the code that shows the messageBox.
I don't see any problem or difficulty there...

hi you just need to adjust your logic

 settings = QtCore.QSettings('ConTest', 'Check-Box status')
 IsHidden = settings.value('check_box_status', check_box_status)

if  not IsHidden :     // its one block   
  msg = QtWidgets.QMessageBox()
  msg.setWindowTitle("What's New")
  msg.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)
  msg.setText(ui_helper.WHAT_IS_NEW)
  check_box = QtWidgets.QCheckBox("Don't show this again")
  msg.setCheckBox(check_box)
  msg.exec_()
  check_box_status = check_box.isChecked()
  settings.setValue("check_box_status", check_box_status)

@mrjj Hi , I have one doubt here. The settings variable here is creating a folder in windows registry editor. But my question is, when i close my application and relaunch it again, will this settings variable not create one more folder?

Therefore the settings have a key string. So that the same, stored value is read in again.

Ok, So should I go ahead with this code?
