Constructor & Destructor Documentation

◆ ThemeChooser()

ThemeChooser::ThemeChooser ( MythScreenStack parent,
const QString &  name = "ThemeChooser" 
)
explicit

Creates a new ThemeChooser Screen.

Parameters
parentPointer to the screen stack
nameThe name of the window

Definition at line 75 of file themechooser.cpp.

◆ ~ThemeChooser()

ThemeChooser::~ThemeChooser ( )
override

Definition at line 84 of file themechooser.cpp.

Member Function Documentation

◆ Create()

bool ThemeChooser::Create ( void  )
overridevirtual

Reimplemented from MythScreenType.

Definition at line 94 of file themechooser.cpp.

◆ Load()

void ThemeChooser::Load ( void  )
overridevirtual

Load data which will ultimately be displayed on-screen or used to determine what appears on-screen (See Warning)

Warning
This method should only load data, it should NEVER perform UI routines or segfaults WILL result. This includes assinging data to any widgets, calling methods on a widget or anything else which triggers redraws. The safest and recommended approach is to avoid any interaction with a libmythui class or class member.

Reimplemented from MythScreenType.

Definition at line 137 of file themechooser.cpp.

◆ Init()

void ThemeChooser::Init ( void  )
overridevirtual

Used after calling Load() to assign data to widgets and other UI initilisation which is prohibited in Load()

Warning
Do NOT confuse this with Load(), they serve very different purposes and most often both should be used when creating a new screen.

Reimplemented from MythScreenType.

Definition at line 418 of file themechooser.cpp.
