Detailed Description

Field Gadget.

Library: dbgadget

The IliDbStringList class defines a string list gadget that displays a list of strings and/or bitmaps and that can be connected to a data source. The list displays the columns (display and bitmap) of the foreign table of the field.

Member Function Documentation

virtual IlBoolean IliDbStringList::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 IliFieldItf.

virtual const IliValue& IliDbStringList::f_getValue

(

IlBoolean

internal = IlFalse

)

const [virtual]

Returns the value of the field.

Parameters:

internal

If IlTrue, the returned value does not necessarily reflect the state of the field as the user sees it.

Returns:

The value.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbStringList::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 IliFieldItf.

virtual IlBoolean IliDbStringList::f_isReadOnly

(

)

const [virtual]

Returns IlTrue if the field is read-only.

Returns:

IlTrue if the field is read-only.

Reimplemented from IliFieldItf.

virtual void IliDbStringList::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 IliDbStringList::f_setForeignTable	(	IliTable *	tbl,
		IlBoolean	owner = IlFalse
	)			[virtual]

Sets the foreign table of the field.

Parameters:

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

Reimplemented from IliFieldItf.

virtual void IliDbStringList::f_setForeignValueColumnName

(

const char *

name

)

[virtual]

Sets the name of the column of the foreign table that will serve as a key, 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 IliDbStringList::f_setReadOnly

(

IlBoolean

flag

)

[virtual]

Sets the read-only property for the field.

Parameters:

flag

The read-only flag.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbStringList::f_setValue	(	const IliValue &	val,
		IlBoolean	internal = IlFalse
	)			[virtual]

Sets the value of the field.

Parameters:

	val	The value.
	internal	If IlFalse, then the external representation and the display of the field are automatically updated.

Returns:

IlTrue if successful, and IlFalse otherwise.

Reimplemented from IliFieldItf.

const char* IliDbStringList::getForeignBitmapColumnName

(

)

const

Returns the column name of the foreign table that will serve as the result when the table is used to display a picture.

Returns:

The column name of the foreign table that will serve as the result when the table is used to display a picture.

void IliDbStringList::setForeignBitmapColumnName

(

const char *

col

)

Sets the column name of the foreign table that will serve as the result when the table is used to display a picture.

Parameters:

col

The column name.
