Detailed Description

Field gadget class.

Library: dbgadget

The IliTableComboBox class defines a combo box gadget that opens a pull-down menu when the user clicks on the combo button. The pull-down menu displays a column of the foreign table of the field. A IliTableComboBox gadget inherits the following properties from the IliFieldItf class:

a value (that may be connected to a data source)
a foreign table
a column of the foreign table known as the value column
a column of the foreign table known as the display column

When a table combo box receives a new value, it looks in the foreign table for a row that has this value in what is referred to as its value column. If such a row is found, the table combo box displays the value contained in what is referred to as the display column of this row. Therefore, a table combo box does not display the new value, but a value which is derived from the initial value through the foreign table. The foreign table serves as a value converter. In addition, if the user edits the value displayed in the table combo box, the edited value is converted back in a reversed version of the procedure described above. A row that contains the newly edited value in its display column is searched for in the foreign table. If such a row is found, the value of the combo box changes to the value contained in the value column of the row. Moreover, the pull-down menu can display several columns of the foreign table. See the function setTablesColumns. However, if you display another dialog, use the IliAbstractTablePopupView class to define your dialog class and replace the pull-down menu by this class. Note: This gadget does not support XP look&feel. If you need a support of the XP look&feel see IliScrolledComboBox class.

Member Function Documentation

virtual void IliTableComboBox::close ( )

virtual

Hides the pull-down menu or dialog box.

The type of object that is hidden depends on the subclass of IliAbstractComboBox being used.

Reimplemented from IliAbstractComboBox.

virtual IlBoolean IliTableComboBox::f_complete ( )

virtual

Updates the internal value of the field, according to its current external representation and its foreign table, provided completion is enabled for the field.

For more information on completion, see the f_iscompletionEnabled member function.

Returns: IlTrue if successful.

Reimplemented from IliFieldItf.

virtual IlBoolean IliTableComboBox::f_externalToInternal ( )

virtual

Updates the internal value of a field according to its current external representation.

Returns: IlTrue if successful and IlFalse otherwise. Note that this may fail due to the fact that not all external representations can be converted to a value object. For example, this is especially true for text fields that are used to edit numeric or date values.

Reimplemented from IliEntryField.

virtual IlBoolean IliTableComboBox::f_isAutoFitPullDown ( ) const

virtual

Returns IlTrue if the width of the pull-down menu is automatically computed so that its contents fit.

Returns

IlTrue if the width of the pull-down menu is automatically computed so that its contents fit. The value returned by this virtual member function is currently meaningful only when the field gadget is one of the following:

IliTableComboBox
IliTableGadget

For a table gadget, this property applies to all table combo boxes contained in the table gadget.

Reimplemented from IliFieldItf.

virtual IlBoolean IliTableComboBox::f_isConsistent ( ) const

virtual

Returns IlTrue if the internal value of the field corresponds to its current external representation.

A return value of IlFalse means that the external representation of the field has been edited by the end-user since the last time one of the member functions, f_setValue, f_externalToInternal, f_internalToExternal or f_complete was successfully called.

Returns: IlTrue if the internal value of the field corresponds to its current external representation.

Reimplemented from IliEntryField.

virtual void IliTableComboBox::f_setAutoFitPullDown ( IlBoolean flag )

virtual

Enables/disables the automatic width computing of the pull-down menu.

Parameters

flag	If `IlTrue`, the width of the pull-down menu is automatically computed so that its contents fit. See the description of `f_isAutoFitPullDown` for more information on this property.

Reimplemented from IliFieldItf.

virtual void IliTableComboBox::f_setForeignDisplayColumnName ( const char * name )

virtual

Sets the name of the column of the foreign table that will serve as a result, when the table is used as a map to convert internal values into external representations.

Parameters

name	The column name.

Reimplemented from IliFieldItf.

virtual void IliTableComboBox::f_setForeignTable	(	IliTable *	tbl,
		IlBoolean	owner = `IlFalse`

Parameters

tbl	The table.
owner	Determines whether the field will own the table.

Reimplemented from IliFieldItf.

virtual void IliTableComboBox::f_setForeignValueColumnName ( const char * name )

Reimplemented from IliFieldItf.

virtual IlBoolean IliTableComboBox::f_setValue	(	const IliValue &	val,
		IlBoolean	internal = `IlFalse`
	)

virtual

Sets the value of the field.

Parameters
