Member Function Documentation

◆ activate()

void NCDialog::activate ( )
virtual

Activate this dialog: Make sure that it is shown as the topmost dialog of this application and that it can receive input.

Implemented from YDialog.

Implementation of YDialog::activate().

This is called e.g. for the next-lower dialog in the dialog stack when the topmost dialog is destroyed: That next-lower dialog is now the active dialog.

◆ location()

virtual const char * NCDialog::location ( ) const
inlineprotectedvirtual

Reimplemented from NCWidget.

◆ openInternal()

void NCDialog::openInternal ( )
protectedvirtual

Internal open() method: Initialize what is left over to initialize after all dialog children have been created. YDialog::setInitialSize() is already called before this in YDailog::open(), so don't call it here again (very expensive!).

This function is called (exactly once during the life time of the dialog) in YDialog::open().

Implemented from YDialog.

◆ pollEventInternal()

YEvent * NCDialog::pollEventInternal ( )
protectedvirtual

Check if a user event is pending. If there is one, return it. If there is none, do not wait for one - return 0.

Implemented from YDialog.

Back-end for YDialog::pollEvent()

◆ preferredWidth()

int NCDialog::preferredWidth ( )
virtual

Reimplemented in NCAskForFile.

◆ setEnabled()

virtual void NCDialog::setEnabled ( bool do_bv)
inlineprotectedvirtual

Pure virtual to make sure every widget implements it. Necessary to make sure that UI requests via YWidget::setEnabled perform, and behave the same way as direct calls to NCWidget::setEnabled.

Implements NCWidget.

◆ waitForEventInternal()

YEvent * NCDialog::waitForEventInternal ( int timeout_millisec)
protectedvirtual

Wait for a user event.

Implemented from YDialog.

Back-end for YDialog::waitForEvent()

◆ wHandleHotkey()

NCursesEvent NCDialog::wHandleHotkey ( wint_t key)
protectedvirtual

Reimplemented from NCWidget.

◆ wHandleInput()

NCursesEvent NCDialog::wHandleInput ( wint_t ch)
protectedvirtual

Reimplemented from NCWidget.

◆ wStyle()

virtual const NCstyle::Style & NCDialog::wStyle ( ) const
inlineprotectedvirtual

Reimplemented from NCWidget.
