mutilple selection int tree

[raj129*]

hi,

i am trying to get label name from the selected tree items.there are some 10 items in a tree, i am randomly selecting few items say, 1st,3rd,5th items. now i need get the selected 3 item name in an array.how can i proceed... with the below code i can read only one selected item name but i need multiple....

GetNumTreeItems (panelHandle, PANEL_TREE, VAL_ALL, 0, VAL_FIRST, VAL_NEXT_PLUS_SELF, 0, &noOfChild); 
   	for(i = 0; i < noOfChild; i ++)
   {
    GetTreeItemAttribute(panelHandle, PANEL_TREE, i, ATTR_SELECTED, &select);
    if(select)
    {
     GetTreeCellAttribute(panelHandle, PANEL_TREE, i, 0, ATTR_LABEL_TEXT, treelabel);
         }
	Fmt(targetstr,"%f",testcaseno);
	}

There is code in the example program \samples\userint\treemenu that does what you want.

Here is another snippet that would work:

    for (error = GetTreeItem(panel, ctrl, VAL_ALL, 0, VAL_FIRST, VAL_NEXT_PLUS_SELF, VAL_SELECTED, &index);
         index >= 0 && error >= 0;
         error = GetTreeItem(panel, ctrl, VAL_ALL, 0, index, VAL_NEXT, VAL_SELECTED, &index))
    {
        // do something with index
    }
 

Hope this helps,

Hi Jared,
with the above code snipet, i can able to read only one item value in a tree. If i select item 1st,3rd & 4th in a tree, index returns values as 4 and takes the 4th value alone in the gettreeitem.it is not returing 1st and 3rd item value though it is selected in tree control.
To be more clear, i have shared my code in which if i select the above mentioned items in a tree, output needs to be "u have selected item1,item3,and item 4" but my code return only one item value which is selected at last.how can i proceed to set multiple items selected? in the attached picture, i have selected item1,3,4 and it return "u have selected item4" but i need "u have selected item1,3and 4"

#include <formatio.h>
#include <userint.h>
#include "Test.h"
#include <cvirte.h>
int parentHandle=0;
int main (int argc, char *argv[])
{
	if (InitCVIRTE (0, argv, 0) == 0)
		return -1;    /* out of memory */
	
	
	parentHandle = LoadPanel(0,"Test.uir",PANEL);
	DisplayPanel(parentHandle);
	RunUserInterface();
	
	return 0;
}

int CVICALLBACK btn_print (int panel, int control, int event,
		void *callbackData, int eventData1, int eventData2)
{	  int index;int error=0;
	   char text[100]={'\0'};
	   char targetstring[260];
	switch (event)
	{
		case EVENT_COMMIT:
			
		for(error = GetTreeItem(parentHandle, PANEL_TREE, VAL_ALL, 0, 
                VAL_FIRST, VAL_NEXT_PLUS_SELF, VAL_SELECTED, &index);
          index >= 0&&error<=0;error = GetTreeItem(parentHandle, PANEL_TREE, VAL_ALL, 0, 
                index, VAL_NEXT, VAL_SELECTED, &index))
    	{
         GetTreeCellAttribute(parentHandle, PANEL_TREE, 
            index, 0, ATTR_LABEL_TEXT, text);
         Fmt(targetstring,"u have Selected %s",text);
		 SetCtrlVal(parentHandle,PANEL_TEXTMSG,targetstring);   
    }															

			break;
	}
	return 0;
}

int CVICALLBACK btn_quit (int panel, int control, int event,
		void *callbackData, int eventData1, int eventData2)
{
	switch (event)
	{
		case EVENT_COMMIT:

			QuitUserInterface(0);
			break;
	}
	return 0;
}

Thanks for attaching the picture.... The problem is that you are using the word "selected" when you mean "checked", or at least that is how I was understanding it. Selection means to be hilited in blue (like when you <ctrl> click, or <shift> click on items when the tree is in multiple selection mode).

From your picture, I see that you want to iterate thru the checked (or marked) items. To do that, change the instances of VAL_SELECTED to VAL_MARKED in your code. Also, if you change the text message control to a text box control, you'll be able to see the output of each iteration.

Hi Jared,

It works well with VAL_MARKED!!!!

i was bit misconfused with VAL_MARKED and VAL_SELECTED.

thanks a lot for ur solution....
