How to close the dialog using close(X) button or cancel push button?

[Gokulnathvc]

How to close the current dialog using X close button or the cancel push button in the dialog? When pressing either of the buttons, the current dialog should close and the rest of the codes should be ignored?

[FelixB]

the "x-Button" behaviour is automatically implemented (assuming you mean the button top right which is generated automatically).

to close via "cancel", you have to connect the clicked()-signal of this button with the "close()"-slot of your dialog.

Groan. Please read at least a few pages of the documentation and try something for yourself before asking how you can implement default behaviour (the close [X] widget) or behaviour that is adequately covered in the QDialog manual page and any number of the bundled examples.

You want QDialog::reject() to "cancel" the dialog, or QDialog::accept() to "OK" the dialog.
