1 - Introduction

In this lesson we are going to learn how to develop large applications using HarbourPWCT (Part 4)

In this part of our lesson we will create a (Sub Window) template to be used later in our development

The (Sub Window) template is a (Server Extension) and it's Class based.

This template uses the component (CG Replace String) to enable us to change the (class name)

and the (window name) quickly.

When you use this template to change the class name you will modify only the step

( PWCT-Code Generator: Replace String (MyClassName) with (mysubwindow) )

Where (mysubwindow) is the class name

To change the window name you will modify only the step

( Data cWindowName Init Value "SubWindowName" )

Developing applications this way will enable you to create many objects of the same class

And you can use these objects at the same time (displaying the same window more than once)

and each object of our class have its own window name stored in the property (cWindowName)

All what you need is to create new object and assign a different window name to the property

(cWindowName) then call the method (ShowWindow) to dispaly the window.

 

Since this is a (Server Extension) to use it you need to generate the source code file (CTRL+R)

Then to add this extension to your application you need to call the generated source code file

And this can be done using the component (Set procedure to)
