Enabling & Disabling Buttons

Question

I am developing an application in Python and I want to have a specific set of buttons set to disabled until another button is clicked first. For Example, When I press the Sim Card button, I want the Sim Report button to be set to enabled.

I have tried to implement the functionality using this solution: How to make push button immediately disabled? but it only disables the button for 5 seconds. I want to only enable a specific button when a condition has been met in a corresponding button. I do not want to generate a report unless the data has been parsed first basically.

Answer 1

You can enable and disable buttons by using button.setEnabled(False) or button.setEnabled(True). As for when they are enabled, just add in the two lines above in the appropriate places to trigger the buttons.

So with your example for instance, start with simReport button disabled. Then in your select_sim_data function, add generate_Sim_Report.setEnabled(True). You can implement this functionality in any methods that need to control whether a button is enabled.
