Class sh::actions::AbstractActionItem

class sh::actions::AbstractActionItem : public QObject, public std::enable_shared_from_this<AbstractActionItem>

Abstract base class for executable actions, submenus of them, and more.

See the subclasses of this class.

They are used at various places. The toolbar and context menus provide them to the user.

They can be registered e.g. in a sh::actions::ActionFactory or returned from sh::filesystem::FilesystemHandler.getActions in order to make them available.

Subclassed by sh::actions::ActionActionItem, sh::actions::HeaderActionItem, sh::actions::SeparatorActionItem, sh::actions::SubmenuActionItem

Public Functions

QString text()

Returns the displayed text for this action.

QString icon()

Returns the icon for this action.

bool enabled()

Checks if this action is enabled.

bool isChecked()

Checks if this action is checked (has a cross in the ui).

bool isCheckable()

Checks if this action is checkable (can have a cross in the ui).

int defaultActionPrecedence() const

Returns the precedence for becoming the default action of a parent submenu.

This e.g. leads to a bold label.

The action with the highest value becomes the default. Only values >0 will be considered. See ActionDefaultPrecedenceValues for reference values.
