base class for widgets which show multi column and multi row data in a grid.

Member Function Documentation

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

it's possible to change the order of the columns

Parameters
fromposition where the column was originally
totarget position

References hk_class::hkdebug().

unsigned int hk_dsgrid::columnscount ( void  )

returns the number of columns shown in the grid.

bool hk_dsgrid::datasource_disable ( void  )
protectedvirtual

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

Reimplemented from hk_dsvisible.

References hk_dsvisible::datasource_disable(), and hk_class::hkdebug().

bool hk_dsgrid::datasource_enable ( void  )
protectedvirtual

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

Reimplemented from hk_dsvisible.

References hk_dsvisible::datasource_enable(), and hk_class::hkdebug().

hk_dsgridcolumn * hk_dsgrid::gridcolumn ( unsigned int  c)

returns a specific gridcolumn

Parameters
cnumber of the column.

References hk_class::hkdebug().

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.

References hk_class::get_tagvalue(), hk_class::hkdebug(), and hk_dsvisible::loaddata().

Referenced by hk_dsquery::loaddata().

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.

References hk_class::hkdebug().

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

References hk_class::hkdebug().

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

you can manually set the gridcolumn definition.

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

References hk_class::hkdebug().

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
slthe strings contain the names of the columns.

References hk_class::hkdebug().

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

sets the new width of a specific column.

Parameters
colnumber of the column
newsizethe new width of the column

References hk_class::hkdebug().

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

References hk_class::hkdebug().

bool hk_dsgrid::table_structure_changes ( void  )
protectedvirtual

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

Reimplemented from hk_dsvisible.
