2.2.4.17.32 GraphLayer::ReorderPlots

ReorderPlots

Description

Reorder plots in a specific group or all plots in GraphLayer.

Syntax

int GraphLayer::ReorderPlots(const vector<uint>& vnIndices, int c1 = 0, BOOL bUndo = FALSE);

Parameters

vnIndices

[input] The indexes of all the plots in the layer or a specific group to be reordered.

The sequence of the indexes determines how to reorder the plots.

c1

[input] The beginning index (counting from 0) of the group you want to reorder.

If you want to reorder all plots, just ignore it.

undo

[input] FALSE as default value. Set true to enable undo block.

Return

-1 if vnIndices does not exist

-2 if the size of vnIndices plus c1 is larger than the total number of plots

-3 if try to reorder a sub part of a group. Maybe you should do UngroupPlots firstly.

0 if success, or the size of vnIndices is zero

Examples

EX1

//reorder all plots
// you will need to have a graph which has exactly 4 plots to use this code
void test_ReorderPlots()
{
    GraphLayer gl = Project.ActiveLayer();//gl is the active layer
	
    vector<uint> vecUI = {1,0,3,2};//vecUI contains the reorder sequence counting from 0

    int nRet = gl.ReorderPlots(vecUI);

    printf("%d",nRet);
}

EX2

//reorder a specific group in graph whose indexes starting from 2
// you will need to have a graph which has at least 2 group of plots to use this code
void test_ReorderPlots()
{
    GraphLayer gl = Project.ActiveLayer();//gl is the active layer
	
    vector<uint> vecUI = {1,0};//the group contains exactly 2 plots

    int nRet = gl.ReorderPlots(vecUI,2);

    printf("%d",nRet);
}
