Member Function Documentation

◆ closeEditor_

void closeEditor_ ( )
privateslot

if cancel in any editor is clicked, the Dialog is closed and changes are rejected

◆ commitAndCloseEditor_

void commitAndCloseEditor_ ( )
privateslot

For closing any editor and updating ParamEditor.

◆ commitAndCloseLineEdit_

void commitAndCloseLineEdit_ ( )
privateslot

... a bit special, because reset uncommited data

◆ createEditor()

QWidget* createEditor ( QWidget *  parent,
const QStyleOptionViewItem &  option,
const QModelIndex &  index 
) const
override

Returns the widget(combobox or QLineEdit) used to edit the item specified by index for editing. Prevents edit operations on nodes' values and types.

◆ eventFilter()

bool eventFilter ( QObject *  editor,
QEvent *  event 
)
overrideprotected

a shortcut to calling commit(), which calls setModelData(); useful for embedded editors, but not for QDialogs etc

◆ exists_()

bool exists_ ( const QString &  name,
QModelIndex  index 
) const
protected

Checks if a name is valid for the entry corresponding to index (checks if it would be duplicate)

◆ hasUncommittedData()

bool hasUncommittedData ( ) const

true if the underlying tree has an open QLineEdit which has uncommitted data

◆ modified

void modified ( bool  ) const
signal

signal for showing ParamEditor if the Model data changed

◆ setEditorData()

void setEditorData ( QWidget *  editor,
const QModelIndex &  index 
) const
override

Sets the data to be displayed and edited by the editor for the item specified by index.

◆ setModelData()

void setModelData ( QWidget *  editor,
QAbstractItemModel *  model,
const QModelIndex &  index 
) const
override

Sets the data for the specified model and item index from that supplied by the editor. If data changed in a cell, that is if it is different from an initial value, then set its background color to yellow and emit the modified signal otherwise make it white.

◆ updateEditorGeometry()

void updateEditorGeometry ( QWidget *  editor,
const QStyleOptionViewItem &  option,
const QModelIndex &  index 
) const
override

Updates the editor for the item specified by index according to the style option given.

Member Data Documentation
