1.1.7 Creating Wizard Dialog

X-Function Wizard DialogWizard Dialog X-Functions support wizard dialogs. To create a wizard dialog, you need n+1 X-Functions, where n is the number of wizard pages. One is the main X-Function. The main X-Function is used to construct wizard pages and then open the wizard dialog if script mode is off, or run without dialog when script mode is on.

Creating a Wizard

The following shows how to create a two page wizard. Page 1 is used to select an XY range, and to specify the sub x range of the selected data range. Page 2 is used to add a rectangle with the specified fill color onto the source graph. The left x and right x of this rectangle are equal to the values of x from/to in Page 1.

Add a header file, wizDlg.h, under the UFF\OriginC\ folder. Put the following code into this header file to derive subclasses from Origin C built-in X-Function wizard classes. The X-Function basic wizard classes are:

XFCore, which is used to save and pass values in each page.
XFWizTheme, which is used to arrange theme settings for each wizard page.
XFWizInputOutputRange, which is used to arrange input and output ranges for each page.
XFWizManager, which is very important and must have a user-defined subclass derived from it. It is used to decide the steps in the wizard.

Press F10 to open X-Function Builder, to create a main X-Function as below.
Click the button to save this X-Function. Close X-Function Builder.

Open Code Builder, open the wizDlg.OXF file and add it to the current workspace. Add the following header files after the line //put additional include files here.

#include <..\OriginLab\XFWiz.h>

#include <event_utils.h>
#include <..\OriginLab\WksOperation.h>
#include <..\OriginLab\WizOperation.h>

#include <..\OriginLab\XFWizDlg.h>
#include <..\OriginLab\XFWizard_utils.h>

#include <..\Originlab\wizDlg.h> // user added header file for this example

Add the following code to the main function wizDlg

WizDlgInputOutputRange objXFWizIO;
if(!xfwiz_construct_input_range(&objXFWizIO, STR_XFNAME_PAGE_1,  iy))
{
	XF_THROW(XFERR_FAIL_TO_UPDATE_GETN_TREE);

if( script )
{
	run_wiz_nodlg(theme, NULL, &objXFWizIO);
}
else
{
	open_wiz_dlg(theme, NULL, &objXFWizIO);
}

Press F10 to open X-Function Builder and create the X-Function wizPage1 for the wizard page 1 as below.
Add the following user-defined header file after the line //put additional include files here, as below.
```
#include <..\Originlab\wizDlg.h> // user added header file for this example
```

Put the following code into the page 1 main function wizPage1.

WizDlgCore* pWizCore = 
	(WizDlgCore*)get_xf_core_handler(NODE_NAME_XF_WIZ_CORE_POINTER);
ASSERT(pWizCore);

// Set X From/To to WizCore class object
pWizCore->SetXRange(xfrom, xto);

Add the following code to the wizPage1 X-Function _event1 function wizPage1_before_execute, to initialize the xfrom and xto controls according to the input data range.

if( PDS_AUTO == okutil_cvt_str_to_predefined_type(trGetN.xfrom.strVal) 
	|| PDS_AUTO == okutil_cvt_str_to_predefined_type(trGetN.xto.strVal) )

	vector vx;
	dr.GetData(DRR_GET_DEPENDENT, 0, NULL, NULL, NULL, &vx);
	
	double from, to;
	vx.GetMinMax(from, to);
	
	trGetN.xfrom.dVal = from;
	trGetN.xto.dVal = to;
}

Open X-Function Builder to create the X-Function wizPage2 for page 2. Set up the X-Function name and variables as below and click the Save button to save.
Open the wizPage2.OXF file in Code Builder, and add it to the current workspace to include header files, as below.
```
//put additional include files here
#include <..\Originlab\wizDlg.h>
#include <..\Originlab\grobj_utils.h>
```

Find the main function wizPage2 and put the following code into it. The code is used to add a rectangle according to the xfrom and xto values assigned in page 1.

WizDlgCore* pWizCore = 
	(WizDlgCore*)get_xf_core_handler(NODE_NAME_XF_WIZ_CORE_POINTER);
ASSERT(pWizCore);

// Get the x from/to values that are specified in Page 1
double xfrom, xto;
pWizCore->GetXRange(xfrom, xto);

// To get input range.
XFWizNavigation* pXFWizNavg = 
	(XFWizNavigation*)(pWizCore->GetXFWizNavigation());
WizDlgInputOutputRange* pwizInputOutputRange = 
	(WizDlgInputOutputRange*)(pXFWizNavg->GetXFWizInputOutputRange());

// Get input ranges from Page 1
Array<DataRange&> arrdr;
if( pwizInputOutputRange->Get(&arrdr, STR_XFNAME_PAGE_1, true) ) 
{
	DataRange& dr = arrdr.GetAt(0);
	
	vector<uint> vUIDs;
	DataPlot dp;
	if( dr.GetPlots(vUIDs) > 0 )
	{
		// Get source graph layer from input range
		dp = (DataPlot)Project.GetObject(vUIDs[0]);
		GraphLayer gl;
		dp.GetParent(gl);
		
		// To add rectangle to graph
		GraphObject go;
		add_rect(gl, go, xfrom, 0, xto, 0, color, 2, LN_VERTICAL, 
			true, false);
	}
}

Using X-Function

Before running the example wizard, you need to create a new worksheet, fill two columns with data, and plot a line graph with two columns.

Run with wizard dialog

Keep the graph window active. Run "wizDlg" in the Command window.
In the dialog that appears, change the values of the xfrom and xto controls. Click the Next button.
In the next page, change the Fill Color control to Blue.
Click the theme button , choose Save As, type in theme1 as the name, and click OK.
Click the Finish button. The wizard dialog closes and a blue rectangle will be added to your source graph.

Run with script mode without dialog X-Function, Execution with Theme

Keep the graph window active. Run "wizDlg s:=1 t:=theme1" in the Command window. No dialog opens and a rectangle will be added to the active graph with the settings specified in the theme file.
