Member Function Documentation

hk_dsgridcolumn * hk_dsgrid::gridcolumn

(

unsigned int

c

)

returns a specific gridcolumn

Parameters:

c

number of the column.

unsigned int hk_dsgrid::columnscount

(

void

)

returns the number of columns shown in the grid.

void hk_dsgrid::set_gridcolumnwidth	(	unsigned int	col,
		int	newwidth
	)

sets the new width of a specific column.

Parameters:

	col	number of the column
	newsize	the new width of the column

void hk_dsgrid::change_columnposition	(	unsigned int	from,
		unsigned int	to
	)

it's possible to change the order of the columns

Parameters:

	from	position where the column was originally
	to	target position

void hk_dsgrid::set_gridcolumns	(	vector< hk_dsgridcolumn > &	c,
		bool	registerchange = true
	)

you can manually set the gridcolumn definition.

Parameters:

c

the new defintion of the gridcolumns, all values in these definitions will be used

void hk_dsgrid::set_gridcolumns

(

list< hk_string > &

sl

)

you can manually set the gridcolumn definition.The new defintion of the gridcolumns, all columns get default values.

Parameters:

sl

the strings contain the names of the columns.

void hk_dsgrid::set_hold_rowdefinition

(

bool

h = true

)

If true and you change the row definitions (i.e. column size) after disabling and reenabling your definitions still exist, if false the rows will be newly built. Default is true.

See also:

set_enablingbehaviour

void hk_dsgrid::set_enablingbehaviour	(	bool	add_col,
		bool	del_col
	)

if set_hold_rowdefinition is true, this function defines what exactly to do during enabling

Parameters:

	add_col	if true, columns of the datasource will be added to the grid if no equivalent gridcolumn exists. Default is false.
	del_col	if true, gridcolumns will be removed if no equivalent columns in the datasource exist. Default is false.

void hk_dsgrid::savedata

(

ostream &

s

)

[virtual]

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

Reimplemented from hk_dsvisible.

void hk_dsgrid::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_dsvisible.

bool hk_dsgrid::datasource_enable

(

void

)

[protected, virtual]

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

Reimplemented from hk_dsvisible.

bool hk_dsgrid::datasource_disable

(

void

)

[protected, virtual]

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

Reimplemented from hk_dsvisible.

bool hk_dsgrid::table_structure_changes

(

void

)

[protected, virtual]

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

Reimplemented from hk_dsvisible.
