Member Function Documentation

void ColourComboBox::includeUnsetEntry ( QString label )

Add an entry at the top of the combo for "no colour selected", with the given label.

Definition at line 44 of file ColourComboBox.cpp.

References m_unsetEntry, and rebuild().

int ColourComboBox::getCurrentColourIndex ( ) const

inline

Get the current colour index.

This is the same as QComboBox::currentIndex() if there is no unset entry, or 1 less than it if includeUnsetEntry() has been used. So if there is an unset entry, and it is selected, this returns -1.
