Member Function Documentation

void hk_presentation::clear_datasourcelist (  void   )

resets the internal datasourcelist and deletes all datasourceobjects except of "nodelete"

list< hk_datasource * > * hk_presentation::datasources (  void   )  const

a list of all existing datasources in this presentation

hk_datasource * hk_presentation::get_datasource (  long  nr  )

returns the datasource with the unique identification number nr

long hk_presentation::new_datasource (  const hk_string &  name, datasourcetype  dt = dt_table )

loads an existing datasource "name". if query=false this datasource is a table else a query. Returns: each presentationdatasource gets a unique number as an identifier.

void hk_presentation::set_automatic_enable_datasources (  bool   )

if true (default) all datasources will be automatically enabled when mode changes to viewmode else you have to enable the datasources manually

void hk_presentation::set_database (  hk_database *  db  )

set the database which is base of this presentation

void hk_presentation::set_designsize (  unsigned int  width, unsigned int  height, bool  registerchange = true )

sets the logic size of the form. Reimplemented in hk_form.

void hk_presentation::set_name (  const hk_string &  n  )

name of the presentation under which it will be stored

hk_string hk_presentation::unique_datasourcename (  long  nr  )

returns a unique name for a datasource looks like : nameofdatasource (uniquenumber) [dependingondatasource] | filter
