Member Function Documentation

void hk_dsgridcolumn::loaddata (  const hk_string &  definition  )  [virtual]

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

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

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

void hk_dsgridcolumn::set_columntype (  enum_columntype  , bool  registerchange = true )

if columntype is columnedit the celldata will be shown as a string if columntype is columnbool the celldata will be shown as a boolean field

void hk_dsgridcolumn::set_columnwidth (  int  , bool  registerchange = true )

the (visible) width of the column

void hk_dsgridcolumn::set_datasource (  hk_datasource *   )  [virtual]

the datasource Reimplemented from hk_dsdatavisible.

void hk_dsgridcolumn::set_displayname (  hk_string  , bool  registerchange = true )

the text displayed in the column header. If not set the columnname will be displayed

void hk_dsgridcolumn::set_listcolumnname (  const hk_string &  listcolumn, bool  registerchange = true )

The column containing the equivalent key to the column set with set_column

void hk_dsgridcolumn::set_listdatasource (  const hk_string &  datasourcename, datasourcetype  dt = dt_table, bool  registerchange = true )

comboboxes need 2 datasources. One (the normal) datasource is set with set_datasource and stores the values in a field. The second datasource contains a list of possible values for this field. Parameters: list  the datasource which contains the values displayed in the combobox

bool hk_dsgridcolumn::set_listpresentationdatasource (  long  n, bool  registerchange = true )  [virtual]

if this combobox is part of a hk_presentation object (i.e. a form) you can set the listdatasource by its unique presentation number

void hk_dsgridcolumn::set_viewcolumnname (  const hk_string &  viewcolumn, bool  registerchange = true )

The column of the listdatasource which will be displayed in the combobox

hk_string hk_dsgridcolumn::value_at (  unsigned  long  )  [virtual]

returns the formatted value of the row 'row' Reimplemented from hk_dsdatavisible.
