Name

GETN_COMBO

Declaration

#define GETN_COMBO(_NODE_NAME, _NODE_LABEL, _DEFAULT_VAL, _COMBO_STR) _tmpSubNode = _tmpNode.AddNumericNode((double)_DEFAULT_VAL, #_NODE_NAME, TRGP_NUMERIC_LIST); TREE_ADD_LABEL(_NODE_LABEL);_tmpSubNode.SetAttribute(STR_COMBO_ATTRIB, _COMBO_STR);

Remark

This macro creates a combo control containing numeric values in the GetN_Box dialogbox.

Parameters

_NODE_NAME

[input] the name of the new node to be added to the tree

_NODE_LABEL

[input] the string value to show the combo name in the dialogbox

_DEFAULT_VAL

Examples

EX1

This example shows the difference in GETN_COMBO, GETN_LIST and GETN_STRLIST

#include <GetNBox.h>

    GETN_LIST(Type, "Analysis Type", 1, "t-Test|Correlation|NLSF|Polynomial Fit|Statistics")
    GETN_STRLIST(WksName, "Worksheet Name", "one", "|one|two|three|four|five") // editable, choose one from list or directly type string into control
 
    if( GetNBox( treeTest, _event_func_ex )) // to open getn dialog
        out_tree( treeTest );
