openSUSE:YaST styleguide detailed popup
A pop up is a small window which pops up over a parent window and where the user can edit some information. It has only one page and appears in the center of the module. It has full window decoration and the module's name in the title bar.
Use a bold headline that informs the user about the settings he can configure within the pop up.
Use a reasonable margin so that the content does not stick to the borders of the pop up.
Down left there is a “Help” button, down right there is an “OK” and “Cancel” button.
Help Opens help text in the center of the module
OK Applies changes and closes the pop up
Cancel Closes the window and discards eventual changes. If the user made some changes, a warning pop up appears, which asks the user, if he really wants to discard his changes.
