* Name: menuCalc.rex
|
|
* Type: Example ooRexx program
|
|
*
|
|
* Description: Demonstrates how to control an application programmatically
|
|
* using the winsystm classes. Does some simple calculations
|
|
* using the Windows Calculator application.
|
|
*
|
|
* This program is similar to userwmgr.rex but more simple to
|
|
* better show what is going on.
|
|
*
|
|
* This example uses some of the public functions provided by
|
|
* the windowsSystem.frm package. That framweowork is an
|
|
* example of how to extract common function into a package and
|
|
* share that function with any number of ooRexx programs.
|
|
*
|
|
* To really understand how this program works, you will need to examine the
|
|
* the code for the external functions in windowsSystem.frm.
|
|
*
|
|
* The table below lists the external functions and classes used in this
|
|
* program and shows where to go to examine the source code for them.

/* Each button in a dialog has a resource ID. When the button is pushed or
|
|
* clicked, the button sends a command (WM_COMMAND) notification to its parent
|
|
* window. The command notification contains the resource ID of the button that
|
|
* was pushed. This is how the dialog knows what button(s) the user pushes or
|
|
* clicks.
|
|
*
|
|
* We can simulate a user pushing buttons by sending commands to the dialog
|
|
* using the resource ID of the button we want pushed. Here we define variables
|
|
* with the IDs of some of the buttons in the calculator application. You can
|
|
* verify that these are the correct ID numbers by exploring the window hiearchy
|
|
* of the calculator application using the displayWindowTree.rex example program
|
|
* that is included with the ooRexx distribution.
