EX3

this example shows how to customize the auto checkbox

#include <GetNbox.h>

// to add Auto checkbox to browser combo control
void  GETN_ADD_AUTO_ex3()
{
    GETN_TREE(tr)    
    
    GETN_COMBO_BUTTON(fname, "Browse", "Picking a Data File", "File", "User.dat|System.dat|Group.dat", "Untitle.dat")  
    //1|test|0
    //1: check
    //test: rename the "auto" checkbox to "test"
    //0: the control will not turn read-only when uncheck the checkbox
	GETN_CURRENT_SUBNODE.SetAttribute(STR_ATTRIB_AUTO, "1|test|0");
    
    if( GetNBox(tr) )
    {
    	TreeNode trAuto = tr.fname;
    	if( AUTO_CHECKED == octree_get_auto_support(&trAuto) )
    		trAuto.strVal = "Untitle.dat";
    	
        out_tree(tr);
    }
}

EX4 Showing and hiding a control based on it's checkbox state.

#include <GetNBox.h>

EX5

this example shows the difference between auto checkbox and left checkbox

void GETN_ADD_AUTO_AND_LEFT_CHECK_Ex()
{
    GETN_TREE(testTree)
    
    //auto checkbox
    double dAutoValue = 1;
    GETN_NUM(start, "Start Time", dAutoValue) GETN_ADD_AUTO(1) SET_AUTO_VALUE(dAutoValue)   

    //left checkbox    
    //GETN_CONTROL_OPTION_BOX and GETN_ADD_LEFT_CHECK are the same
    GETN_STR_GROUP(ctrlh, "Uncheck to hide", "A", "|A|C|R|V|Y") GETN_CONTROL_OPTION_BOX(0)    
    GETN_NUM(ctrle, "Uncheck to disable", 1.23) GETN_ADD_LEFT_CHECK(0)  GETN_ADD_LEFT_CHECK_TYPE(DYNA_USE_CHECK_TYPE_ENABLE)

    if(GetNBox(testTree, NULL, NULL, NULL, NULL))
    {
    	//show how to reset the value to auto value
    	TreeNode trAuto = testTree.end;    	
    	tree_check_replace_auto(testTree.end, dAutoValue);
    	
    	//show how to get the status of left checkbox
    	if( 0 == GetN_get_left_checkbox(testTree.ctrlh) )
			testTree.RemoveChild("ctrlh");
    	
    	//another way to get 
    	if( tree_is_left_checkbox_checked(testTree.ctrle) )
    		out_str("ctrle is checked");
