Detailed Description

base class for visible widgets without column data connection

Version:

Revision: 1.39

Author:: Horst Knorr (hk_classes@knoda.org)

This is the base class for visible widgets which do not need access to the data, but do have to know whether or not a datasource is enabled and which row is the actual one.

Member Function Documentation

void hk_dsvisible::savedata ( ostream & s ) [virtual]

stores the object's values to stream s. Especially used to store queries, forms and reports

Reimplemented from hk_visible.

Reimplemented in hk_button, hk_dscombobox, hk_dsdatavisible, hk_dsgrid, hk_dsgridcolumn, and hk_subform.

void hk_dsvisible::loaddata ( xmlNodePtr definition ) [virtual]

loads the object's values out of the definition string. Especially used to load queries, forms and reports

Reimplemented from hk_visible.

Reimplemented in hk_button, hk_dscombobox, hk_dsdatavisible, hk_dsgrid, hk_dsgridcolumn, and hk_subform.

void hk_dsvisible::set_before_row_change_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the before_row_change action The before_row_change action before the current row changes

void hk_dsvisible::set_after_row_change_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the after_row_change action The after_row_change action after the current row changes

void hk_dsvisible::set_before_update_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the before_update action The before_update action before data changes will be stored

void hk_dsvisible::set_after_update_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the after_update action The after_update action after data changes will be stored

void hk_dsvisible::set_before_delete_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the before_delete action The before_delete action before the current row will be deleted

void hk_dsvisible::set_after_delete_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the after_delete action The after_delete action after the current row was deleted

void hk_dsvisible::set_before_insert_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the before_insert action The before_insert action before a new row will be inserted

void hk_dsvisible::set_after_insert_action	(	const hk_string &	,
		bool	registerchange = `true`,
		bool	force_setting = `true`
	)

sets the script for the after_insert action The after_insert action after a new row was inserted

virtual void hk_dsvisible::widget_specific_insert_mode ( void ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasource will be set to insert_mode. Has to be rewritten for a new widget

See also:: before_row_change.

virtual bool hk_dsvisible::widget_specific_row_change ( void ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasource has changed the row. Has to be rewritten for a new widget

See also:: before_row_change.

Reimplemented in hk_dscombobox.

virtual void hk_dsvisible::widget_specific_enable_disable ( void ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: defines whether the widget should be enabled or disabled. Has to be rewritten for a new widget

void hk_dsvisible::before_row_change ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: called from hk_datasource before it tries to change the row or disable widget can i.e. store changed data there

bool hk_dsvisible::datasource_disable ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasources is disabling

Reimplemented in hk_dscombobox, hk_dsdatavisible, and hk_dsgrid.

bool hk_dsvisible::datasource_enable ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasources is enabling

Reimplemented in hk_dscombobox, hk_dsdatavisible, and hk_dsgrid.

void hk_dsvisible::datasource_delete ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasources is destroyed

Reimplemented in hk_dsdatavisible.

void hk_dsvisible::row_added ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called when the datasources creates new columns i.e.when enabling,disabling or when a depending datasource has to requery its rows.

virtual bool hk_dsvisible::before_columns_deleted ( void ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called before the columns will be deleted. usually column pointers will be set to NULL in this function. i.e.when enabling,disabling or when a depending datasource has to requery its rows.

Reimplemented in hk_dsdatavisible, and hk_importcsv.

virtual bool hk_dsvisible::table_structure_changes ( void ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called after the columnstructure of a table was successfully altered.

Reimplemented in hk_dsgrid.

void hk_dsvisible::before_source_vanishes ( void ) [protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called before the database will be closed.(i.e when a new database will be created and the old one will be destroyed by hk_connection

virtual void hk_dsvisible::widget_specific_presentationdatasource ( long ) [inline, protected, virtual]

FOR WIDGET DEVELOPERS ONLY: will be automatically called before the presentationdatasource will be set
