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.

// 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);
}
}
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.
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.
