Detailed Description

A small helper to get access to all available color schemes and activating a scheme in the QApplication.

This is useful for applications which want to provide a selection of custom color schemes to their user. For example it is very common for photo and painting applications to use a dark color scheme even if the default is a light scheme. Since version 5.67 it also allows going back to following the system color scheme.

The model() member function provides access to the KColorSchemeModel that the KColorSchemeManager uses which holds all the available color schemes. A possible usage looks like the following:

KColorSchemeManager *schemes = new KColorSchemeManager(this);
QListView *view = new QListView(this);
view->setModel(schemes->model());
connect(view, &QListView::activated, schemes, &KColorSchemeManager::activateScheme);

A convenience function that creates a KActionMenu that contains and activates color schemes exists in KColorSchemeMenu::createMenu

By default KColorSchemeManager remembers the activated color scheme and restores it on the next start of the application. Use setAutosaveChanges() to change this behavior.

Member Function Documentation

activateScheme

void KColorSchemeManager::activateScheme ( const QModelIndex & index )

slot

Activates the KColorScheme identified by the provided index.

Installs the KColorScheme as the QApplication's QPalette.

Parameters

index

The index for the KColorScheme to activate. The index must reference the QAbstractItemModel provided by model. Since version 5.67 passing an invalid index activates the system scheme.

model()

Definition at line 222 of file kcolorschememanager.cpp.

activeSchemeId()

QString KColorSchemeManager::activeSchemeId

(

)

const

Returns the id of the currently active scheme or an empty string if the default scheme is active.

Since

5.107

Definition at line 249 of file kcolorschememanager.cpp.

activeSchemeName()

QString KColorSchemeManager::activeSchemeName

(

)

const

Returns the name of the currently active scheme or an empty string if the default scheme is active.

Since

6.6

Definition at line 254 of file kcolorschememanager.cpp.

indexForScheme()

QModelIndex KColorSchemeManager::indexForScheme

(

const QString &

name

)

const

Returns the model index for the scheme with the given name.

If no such scheme exists an invalid index is returned. If you pass an empty string the index that is equivalent to going back to following the system scheme is returned for versions 5.67 and newer.

model

Definition at line 207 of file kcolorschememanager.cpp.

indexForSchemeId()

QModelIndex KColorSchemeManager::indexForSchemeId

(

const QString &

id

)

const

Returns the model index for the scheme with the given id.

If no such scheme exists an invalid index is returned. If you pass an empty string the index returned is equivalent to going back to following the system scheme.

6.6

Definition at line 198 of file kcolorschememanager.cpp.

instance()

KColorSchemeManager * KColorSchemeManager::instance ( )

static

Returns the manager for the current application instance.

If no instance is existing, it will be constructed. Must be called after construction of the gui application instance.

Returns

color scheme manager for the current application instance

Since

6.6

Definition at line 259 of file kcolorschememanager.cpp.

model()

QAbstractItemModel * KColorSchemeManager::model

(

)

const

A QAbstractItemModel of all available color schemes.

The model provides the name of the scheme in Qt::DisplayRole, a preview in Qt::DelegateRole and the full path to the scheme file in Qt::UserRole. The system theme has an empty Qt::UserRole.

Returns

Model of all available color schemes.

KColorSchemeModel

Definition at line 177 of file kcolorschememanager.cpp.

saveSchemeToConfigFile()

void KColorSchemeManager::saveSchemeToConfigFile

(

const QString &

schemeName

)

const

Saves the color scheme to config file.

The scheme is saved by default whenever it's changed. Use this method when autosaving is turned off, see setAutosaveChanges().

Since

5.89

Definition at line 241 of file kcolorschememanager.cpp.

setAutosaveChanges()

void KColorSchemeManager::setAutosaveChanges

(

bool

autosaveChanges

)

Sets color scheme autosaving.

Default value is true. If this is set to false, the scheme is not going to be remembered when the application is restarted.

Parameters

autosaveChanges

Enables/Disables autosaving of the color scheme.

Since

5.89
