Member Function Documentation

◆ cancelEditor()

void KexiFormDataItemInterface::cancelEditor ( )

Definition at line 62 of file kexiformdataiteminterface.cpp.

◆ columnInfo()

virtual KexiDB::QueryColumnInfo * KexiFormDataItemInterface::columnInfo ( ) const

inlinevirtual

Returns: database column information for this item

Implements KexiDataItemInterface.

Definition at line 90 of file kexiformdataiteminterface.h.

◆ dataSource()

TQString KexiFormDataItemInterface::dataSource ( ) const

inline

Returns: the name of the data source for this widget. Data source usually means here a table or query, a field name or an expression.

Definition at line 40 of file kexiformdataiteminterface.h.

◆ dataSourceMimeType()

TQCString KexiFormDataItemInterface::dataSourceMimeType ( ) const

inline

Returns: the mime type of the data source for this widget. Data source mime type means here types like "kexi/table" or "kexi/query" in.the data source is set to object (as within form or subform) or is empty if the data source is set to table field or query column.

Definition at line 50 of file kexiformdataiteminterface.h.

◆ field()

KexiDB::Field * KexiFormDataItemInterface::field ( ) const

virtual

Returns: database column information for this item

Implements KexiDataItemInterface.

Reimplemented in KexiDBComboBox.

Definition at line 47 of file kexiformdataiteminterface.cpp.

◆ hasDisplayedDefaultValue()

virtual bool KexiFormDataItemInterface::hasDisplayedDefaultValue ( ) const

inlinevirtual

Returns: true if default value is displayed for this item.

Definition at line 66 of file kexiformdataiteminterface.h.

◆ hideWidget()

virtual void KexiFormDataItemInterface::hideWidget ( )

inlinevirtual

Does nothing, because within forms, widgets are always visible.

Reimplemented from KexiDataItemInterface.

Definition at line 107 of file kexiformdataiteminterface.h.

◆ keyPressed()

virtual bool KexiFormDataItemInterface::keyPressed ( TQKeyEvent * ke )

inlinevirtual

Reimplemented in KexiDBAutoField, KexiDBComboBox, KexiDBImageBox, and KexiDBLineEdit.

Definition at line 132 of file kexiformdataiteminterface.h.

◆ setColumnInfo()

virtual void KexiFormDataItemInterface::setColumnInfo ( KexiDB::QueryColumnInfo * cinfo )

inlinevirtual

Used internally to set database column information. Reimplement if you need to do additional actions, e.g. set data validator based on field type. Don't forget about calling superclass implementation.

Implements KexiDataItemInterface.

Reimplemented in KexiDBAutoField, KexiDBComboBox, KexiDBImageBox, KexiDBLabel, KexiDBLineEdit, and KexiDBTextEdit.

Definition at line 96 of file kexiformdataiteminterface.h.

◆ setDataSource()

void KexiFormDataItemInterface::setDataSource ( const TQString & ds )

inline

Sets the name of the data source for this widget. Data source usually means here a table or query or field name name.

Definition at line 44 of file kexiformdataiteminterface.h.

◆ setDataSourceMimeType()

void KexiFormDataItemInterface::setDataSourceMimeType ( const TQCString & ds )

inline

Sets the mime type of the data source for this widget. Data source usually means here a "kexi/table" or "kexi/query".

See also: dataSourceMimeType()

Definition at line 55 of file kexiformdataiteminterface.h.

◆ setDisplayDefaultValue()

void KexiFormDataItemInterface::setDisplayDefaultValue	(	TQWidget *	widget,
		bool	displayDefaultValue )

virtual

If displayDefaultValue is true, the value set by KexiDataItemInterface::setValue() is displayed in a special way. Used by KexiFormDataProvider::fillDataItems(). widget is equal to 'this'. You can reimplement this in the widget. Always call the superclass' implementation. setDisplayDefaultValue(.., false) is called in KexiFormScrollView::valueChanged() as a response on data change performed by user.

Reimplemented in KexiDBAutoField, KexiDBCheckBox, KexiDBLineEdit, and KexiDBTextEdit.

Definition at line 52 of file kexiformdataiteminterface.cpp.

◆ setInvalidState()

virtual void KexiFormDataItemInterface::setInvalidState ( const TQString & displayText )

pure virtual

Sets 'invalid' state, e.g. a text editor widget should display text displayText and become read only to prevent entering data, because updating at the database backend is not available. displayText is usually set to something i18n'd like "#NAME?". Note: that even widgets that usualy do not display texts (e.g. pixmaps) should display displayText too.

Implemented in KexiDBAutoField, KexiDBCheckBox, KexiDBDateEdit, KexiDBDateTimeEdit, KexiDBDoubleSpinBox, KexiDBForm, KexiDBImageBox, KexiDBIntSpinBox, KexiDBLabel, KexiDBLineEdit, KexiDBTextEdit, and KexiDBTimeEdit.

◆ setReadOnly()

virtual void KexiFormDataItemInterface::setReadOnly ( bool readOnly )

pure virtual

Changes 'read only' flag, for this widget. Typically this flag can be passed to a widget itself, e.g. KLineEdit::setReadOnly(bool).

Implemented in KexiDBAutoField.

◆ setVisibleColumnInfo()

virtual void KexiFormDataItemInterface::setVisibleColumnInfo ( KexiDB::QueryColumnInfo * cinfo )

inlinevirtual

Used internally to set visible database column information. Reimplemented in KexiDBComboBox: except for combo box, this does nothing.

Reimplemented in KexiDBComboBox.

Definition at line 100 of file kexiformdataiteminterface.h.

◆ showWidget()

virtual void KexiFormDataItemInterface::showWidget ( )

inlinevirtual

Does nothing, because within forms, widgets are always visible.

Reimplemented from KexiDataItemInterface.

Definition at line 110 of file kexiformdataiteminterface.h.

◆ undoChanges()

void KexiFormDataItemInterface::undoChanges ( )

virtual

Undoes changes made to this item - just resets the widget to original value. Note: This is internal method called by KexiFormScrollView::cancelEditor(). To cancel editing of the widget's data from the widget's code, use KexiFormDataItemInterface::cancelEditor(). Reimplemented in KexiDBComboBox to also revert the visible value (i.e. text) to the original state.

Reimplemented in KexiDBComboBox.
