Problem with MessageDLG and Close Button.
« on: May 22, 2021, 12:42:52 am »
I have a MessageDLG having two buttons, Yes and No. But when I click the Close button is like I clicked the Yes button.

Code: Pascal  [Select][+][-]
  1. if (MessageDLG('My title', '¿My question?',
  2.         mtConfirmation, [mbYes, mbNo], 0) = mrNo) then Exit;
  3.

Do it like this:

Code: Pascal  [Select][+][-]
  1. if (MessageDLG('My title', '¿My question?',
  2.         mtConfirmation, [mbYes, mbNo], 0) <>mrYes) then Exit;
  3.

Which OS?
Which WidgetSet?
Which Lazarus?
This piece of code:
Code: Pascal  [Select][+][-]
  1. messagedlg('Title','Message',mtInformation,[mbYes,mbNo],0);
for me only gives 3 possible result values:
mrNo if I click "No"
mrYes if I click "Yes"
mrCancel if I press Escape or close the dialog using the X border icon.

This is how it was designed to work, if it does not, then something is wrong.
