Static Protected Member Functions inherited from QObject | |
QByteArray | normalizeSignalSlot (const char *signalSlot) |
A tree based widget for editing expression context scope variables.
The widget allows editing variables from a QgsExpressionContextScope, and can optionally also show inherited variables from a QgsExpressionContext.
Definition at line 39 of file qgsvariableeditorwidget.h.
QgsVariableEditorWidget::QgsVariableEditorWidget | ( | QWidget * | parent = nullptr | ) |
Constructor for QgsVariableEditorWidget.
parent | parent widget |
Definition at line 36 of file qgsvariableeditorwidget.cpp.
QgsVariableEditorWidget::~QgsVariableEditorWidget | ( | ) |
Definition at line 72 of file qgsvariableeditorwidget.cpp.
|
inline |
Returns the current expression context for the widget.
QgsVariableEditorWidget widgets are created with an empty context by default.
Definition at line 66 of file qgsvariableeditorwidget.h.
QgsExpressionContextScope * QgsVariableEditorWidget::editableScope | ( | ) | const |
Returns the current editable scope for the widget.
Definition at line 126 of file qgsvariableeditorwidget.cpp.
|
slot |
Reloads all scopes from the editor's current context.
This method should be called after adding or removing scopes from the attached context.
Definition at line 108 of file qgsvariableeditorwidget.cpp.
|
signal |
Emitted when the user has modified a scope using the widget.
void QgsVariableEditorWidget::setContext | ( | QgsExpressionContext * | context | ) |
Overwrites the QgsExpressionContext for the widget.
Setting a context allows the widget to show all inherited variables for the context, and highlight any overridden variables within scopes.
context | expression context |
Definition at line 102 of file qgsvariableeditorwidget.cpp.
void QgsVariableEditorWidget::setEditableScopeIndex | ( | int | scopeIndex | ) |
Sets the editable scope for the widget.
Only variables from the editable scope can be modified by users.
scopeIndex | index of current editable scope. Set to -1 to disable editing and make the widget read-only. |
Definition at line 115 of file qgsvariableeditorwidget.cpp.
|
inline |
Sets the setting group for the widget.
QgsVariableEditorWidget widgets with the same setting group will synchronise their settings, eg the size of columns in the tree widget.
group | setting group |
Definition at line 88 of file qgsvariableeditorwidget.h.
|
inline |
Returns the setting group for the widget.
QgsVariableEditorWidget widgets with the same setting group will synchronise their settings, eg the size of columns in the tree widget.
Definition at line 96 of file qgsvariableeditorwidget.h.
|
overrideprotectedvirtual |
Reimplemented from QWidget.
Definition at line 78 of file qgsvariableeditorwidget.cpp.
QgsStringMap QgsVariableEditorWidget::variablesInActiveScope | ( | ) | const |
Returns a map variables set within the editable scope.
Read only variables are not returned. This method can be used to retrieve the variables edited an added by users via the widget.
