Setting of the items by the method

Use addItem method to add items to the list with a string and position. If the position is omitted, add it to the end of the list. The following program is a sample of adding item to the list.

#include <WScom.h>
#include <WSCfunctionList.h>
#include <WSCbase.h>
//----------------------------------------------------------
//Function for the event procedure
//----------------------------------------------------------
#include <WSClist.h>
extern WSClist* newlist_001;
void btnep1(WSCbase* object){
  //Delete all the items of the list.
  newlist_001->delAll();
  //Add an item to the last of the list.
  newlist_001->addItem("item1");
  newlist_001->addItem("item2");
  newlist_001->addItem("item3");
  newlist_001->addItem("item4");
  //Add an item to the specified position of the list.
  newlist_001->addItem("item0",0);//0 :top
  newlist_001->addItem("item5",-1);//-1 :last

  //Update the modified list.
  newlist_001->updateList();
}
static WSCfunctionRegister  op("btnep1",(void*)btnep1);

Setting of the items by the property

the property WSNdata can be used for setting the items of the list, if it is a comparatively little number of the items. In such case, set the property WSNdataSource to WS_DATA_SOURCE_NONE, and set the items which is punctuated with comma every one item to the property WSNdata.

#include <WScom.h>
#include <WSCfunctionList.h>
#include <WSCbase.h>
//----------------------------------------------------------
//Function for the event procedure
//----------------------------------------------------------
#include <WSClist.h>
extern WSClist* newlist_001;
void btnep1(WSCbase* object){
  //Delete all the items of the list.
  newlist_001->delAll();
  //Set the items of the list by the property
  newlist_001->setProperty(WSNdataSource,WS_DATA_SOURCE_NONE);
  newlist_001->setProperty(WSNdata,"item0\nitem1\nitem2\nitem3\nitem4");
}
static WSCfunctionRegister  op("btnep1",(void*)btnep1);

It is possible to indicate the specified ICON by icon file name as following program. Set True to the property WSNuseIcon and Set the items as following format. If it is omitted,the value of WSNiconPixmap is used for default icon.

  format:
  ICON1filename,string1ofTheItem\n ICON2filename,string2ofTheItem\n...

void btnep1(WSCbase* object){
  //Delete all the list of the list
  newlist_001->delAll();
  //Set the items of the list by the property
  newlist_001->setProperty(WSNdataSource,WS_DATA_SOURCE_NONE);
  newlist_001->setProperty(WSNdata,
     "$(WSDIR)/sys/pixmaps/bi16.xpm,item1\nitem2\nitem3");
}
static WSCfunctionRegister  op("btnep1",(void*)btnep1);

Setting of the items from the file directly

It is possible to set the items from the file directly. In such case at first,set WS_DATA_SOURCE_FILE to the property WSNdataSource, and set the file name to the property WSNdataSourceName as following program.

#include <WScom.h>
#include <WSCfunctionList.h>
#include <WSCbase.h>
//----------------------------------------------------------
//Function for the event procedure
//----------------------------------------------------------
#include <WSClist.h>
extern WSClist* newlist_001;
void btnep1(WSCbase* object){
  //Delete all the items of the list
  newlist_001->delAll();
  //Set the items from file directly
  newlist_001->setProperty(WSNdataSource,WS_DATA_SOURCE_FILE);
  newlist_001->setProperty(WSNdataSourceName,"data.txt");
}
static WSCfunctionRegister  op("btnep1",(void*)btnep1);

//data.txt contains...
$(WSDIR)/sys/pixmaps/bi16.xpm,item1
item2
item3
item4
$(WSDIR)/sys/pixmaps/bi16.xpm,item5
item6
item7
item8

Setting of the items from the other instance

It is possible to set the items from the data source target property of the other instances. In such case, set WS_DATA_SOURCE_INSTANCE to the property WSNdataSource, and set the instance name to the property WSNdataSourceName. In the following example, a WSCtextField instance are specified to the property WSNdataSourceName and then it sets the string data of it to the list.

#include <WScom.h>
#include <WSCfunctionList.h>
#include <WSCbase.h>
//----------------------------------------------------------
//Function for the event procedure
//----------------------------------------------------------
#include <WSClist.h>
extern WSClist* newlist_001;
void btnep1(WSCbase* object){
  //Delete all the items of the list
  newlist_001->delAll();
  //Set the items from the other instances
  newlist_001->setProperty(WSNdataSource,WS_DATA_SOURCE_INSTANCE);
  newlist_001->setProperty(WSNdataSourceName,"newtext_000");
}
static WSCfunctionRegister  op("btnep1",(void*)btnep1);
