Detailed Description

- - -The TQSqlPropertyMap class is used to map widgets to SQL fields. -

- -

The SQL module uses TQt object - properties to insert and extract values from editor -widgets. -

This class is used to map editors to SQL fields. This works by -associating SQL editor class names to the properties used to -insert and extract values to/from the editor. -

For example, a TQLineEdit can be used to edit text strings and -other data types in TQDataTables or TQSqlForms. Several properties -are defined in TQLineEdit, but only the text property is used to -insert and extract text from a TQLineEdit. Both TQDataTable and -TQSqlForm use the global TQSqlPropertyMap for inserting and -extracting values to and from an editor widget. The global -property map defines several common widgets and properties that -are suitable for many applications. You can add and remove widget -properties to suit your specific needs. -

If you want to use custom editors with your TQDataTable or -TQSqlForm, you must install your own TQSqlPropertyMap for that table -or form. Example: -

-    TQSqlPropertyMap *myMap  = new TQSqlPropertyMap();
-    TQSqlForm        *myForm = new TQSqlForm( this );
-    MyEditor myEditor( this );
-
-    // Set the TQSqlForm's record buffer to the update buffer of
-    // a pre-existing TQSqlCursor called 'cur'.
-    myForm->setRecord( cur->primeUpdate() );
-
-    // Install the customized map
-    myMap->insert( "MyEditor", "content" );
-    myForm->installPropertyMap( myMap ); // myForm now owns myMap
-    ...
-    // Insert a field into the form that uses a myEditor to edit the
-    // field 'somefield'
-    myForm->insert( &myEditor, "somefield" );
-
-    // Update myEditor with the value from the mapped database field
-    myForm->readFields();
-    ...
-    // Let the user edit the form
-    ...
-    // Update the database fields with the values in the form
-    myForm->writeFields();
-    ...
-

- -

You can also replace the global TQSqlPropertyMap that is used by -default. (Bear in mind that TQSqlPropertyMap takes ownership of the -new default map.) -

-    TQSqlPropertyMap *myMap = new TQSqlPropertyMap;
-
-    myMap->insert( "MyEditor", "content" );
-    TQSqlPropertyMap::installDefaultMap( myMap );
-    ...

Member Function Documentation

TQSqlPropertyMap::TQSqlPropertyMap () -

Constructs a TQSqlPropertyMap. -

The default property mappings used by TQt widgets are: -

Widgets	Property -
TQCheckBox, -TQRadioButton -	checked -
TQComboBox, -TQListBox -	currentItem -
TQDateEdit -	date -
TQDateTimeEdit -	dateTime -
TQTextBrowser -	source -
TQButton, -TQDial, -TQLabel, -TQLineEdit, -TQMultiLineEdit, -TQPushButton, -TQTextEdit, -	text -
TQTimeEdit -	time -
TQLCDNumber, -TQScrollBar -TQSlider, -TQSpinBox -	value -

- -

TQSqlPropertyMap::~TQSqlPropertyMap () `[virtual]` -

-Destroys the TQSqlPropertyMap. -

Note that if the TQSqlPropertyMap is installed with -installPropertyMap() the object it was installed into, e.g. the -TQSqlForm, takes ownership and will delete the TQSqlPropertyMap when -necessary. - -

TQSqlPropertyMap * TQSqlPropertyMap::defaultMap () `[static]` -

-Returns the application global TQSqlPropertyMap. - -

void TQSqlPropertyMap::insert ( const TQString & classname, const TQString & property ) -

-Insert a new classname/property pair, which is used for custom SQL -field editors. There must be a TQ_PROPERTY clause in the classname class declaration for the property. - -

Example: sql/overview/custom1/main.cpp. -

void TQSqlPropertyMap::installDefaultMap ( TQSqlPropertyMap * map ) `[static]` -

-Replaces the global default property map with map. All -TQDataTable and TQSqlForm instantiations will use this new map for -inserting and extracting values to and from editors. -TQSqlPropertyMap takes ownership of \a map, and destroys it when it is no longer needed. - -

TQVariant TQSqlPropertyMap::property ( TQWidget * widget ) -

-Returns the mapped property of widget as a TQVariant. - -

void TQSqlPropertyMap::remove ( const TQString & classname ) -

-Removes classname from the map. - -

void TQSqlPropertyMap::setProperty ( TQWidget * widget, const TQVariant & value ) `[virtual]` -

-Sets the property of widget to value. - - -
