WinBinder Part 2

Introduction

PHP is an excellent scripting language primarily designed for dynamic web sites however it also contains a command line interface. You run this via a command window although powerful it lacks a friendly user interface. The WinBinder project addressed this with a neat extension allowing a user to create windows applications.

This tutorial describes a slightly modified version that is portable and runs straight out of the box. The tutorial assumes you have extracted a copy as explained on this page.

Examples

To really appreciate WinBinders capabilities run the examples in folder C:\us_wb\wb\examples. All WinBinder windows scripts have the extension phpw you will notice that each script has a corresponding batch file. Double click on a batch file to run its associated script. These batch files were added purely for portability and connivance. (See PHC-win how to create executables)

Run manytests_main.bat it provides an excellent example showing all controls available.

Form Editor

Form editor is an excellent tool for positioning Windows controls this overview will quickly get you up and running:

Navigate to folder C:\us_wb\wb\form_editor and

double click on batch file Run_form_editor.bat this runs the form editor.

You will see three floating windows shown on the right.

  • A) Main application window
  • B) The application you are designing
  • C) Control (component) selector you can close this and use the drop down menu D)


  • E) After adding a control they are listed in this window. Click any item in the
    list to select a control, alternatively click on a control in the application design window.
  • F) This window displays additional styles you can add to a control.
  • G) These four controls allow you to finely tune the position of a selected control


Explore

Explore the form-editor, add controls move them around.
Get a feel for laying out controls.

Delete a control

You can delete a control by first selecting it and use menu Edit > Delete control

Preview application

  • Select View > Preview form
  • Displays what an application will look like


The form editor does not add functionality to any controls it is purely a layout tool.
Saving a project automatically exports a PHP script (file) containing layout information
this you can use either directly or cut and paste parts you require.

Tutorial

This tutorial is intended to show the mechanics of creating a windows application using WinBinder and PHC-Win.

So as not to mask details of this process the example is intentionally basic.

Specification

The application has two buttons each toggling the state of it's corresponding image.

Several small files are used these simulate a larger project and demonstrate PHC-Win capabilities.

Top

Preliminary

To store files and resources every application requires a main folder.

Create a new folder named my_app (or any other name) in folder C:\us_wb (can be a different location).

Reason for choosing this location is one of portability, you can copy folder us_wb to a USB memory stick and take your entire projects with you.

Basic Window app

Basic Window app:

Each windows application has a common format to save typing you will find a template in folder C:\us_wb\wb\us_tutorial copy the two files z_basic.bat and z_basic.phpw to folder C:\us_wb\my_app.

  • z_basic.bat Required to run the application z_basic.phpw. It opens a command window that does not close while the application is running any PHP error messages are displayed in this window.
  • z_basic.phpw This template is our starting point for a new application.


Errors:

Well! Even from this starting point we have introduced errors!

Running z_basic.bat (Double click on file) produces the following:

The system cannot find the path specified.
Press any key to continue . . .

The error message is clear both files contain incorrect paths.

These files contain relative paths “..\php” the two periods means move up one folder level and down into folder php however it can not find the folder php. This folder resides inside folder “wb” hence must be included in the paths as shown in the next section.

 

z_basic.bat

..\php\php.exe -c ..\php\php-wb.ini z_basic.phpw

z_basic.phpw

<?php
Include "../php/include/winbinder.php";       // Location Of Winbinder Library

//--- Constants ---------------------------------------------------------------

//=== 1) Create main window ---------------------------------------------------
$mainwin = wb_create_window(NULL, AppWindow, "z_basic", 320, 240);

//=== 2) Create controls for the main window ----------------------------------

//=== 3) Assign handler function to the main window  --------------------------
wb_set_handler($mainwin, "process_main");       

//=== 5) Enter application loop -----------------------------------------------
wb_main_loop();                                  

//=== 4) Handler Function -----------------------------------------------------
function process_main($window, $id) 
{
  switch($id) { 

   case IDCLOSE:                          // Constant IDCLOSE (8) predefined 
    wb_destroy_window($window);           // Destroy the window
    break; 
  }
}
?>

Basic Window app corrected paths

Basic Window app corrected paths:

After correcting the path run z_basic.bat again.

This time the basic windows application will run.


Our application looks a bit sparse however the structure is in place.

We will use the form editor to layout all controls this will automatically provide code for constants and control creation sections.

However before doing this it is worth making a list of ID names and caption values to be used in the application.

We have two buttons these can have the following ID’s and captions:

  • IDC_BUTTONRED1 - Button ID
  • Red 1 - Button caption - Code toggles between Red 1 and Green 1
  • IDC_BUTTONRED2 - Button ID
  • Red 2 - Button caption - Code toggles between Red 2 and Green 2
  • IDC_FRAMERED1 - An image frame to contain image red.bmp
  • IDC_FRAMEGREEN1 - An image frame to contain image green.bmp
  • IDC_FRAMERED2 - An image frame to contain image red.bmp
  • IDC_FRAMEGREEN2 - An image frame to contain image green.bmp

 

z_basic.bat

..\wb\php\php.exe -c ..\wb\php\php-wb.ini z_basic.phpw

z_basic.phpw

<?php
Include "../wb/php/include/winbinder.php";       // Location Of Winbinder Library

//--- Constants ---------------------------------------------------------------

//=== 1) Create main window ---------------------------------------------------
$mainwin = wb_create_window(NULL, AppWindow, "z_basic", 320, 240);

//=== 2) Create controls for the main window ----------------------------------

//=== 3) Assign handler function to the main window  --------------------------
wb_set_handler($mainwin, "process_main");       

//=== 5) Enter application loop -----------------------------------------------
wb_main_loop();                                  

//=== 4) Handler Function -----------------------------------------------------
function process_main($window, $id) 
{
  switch($id) { 

   case IDCLOSE:                          // Constant IDCLOSE (8) predefined 
    wb_destroy_window($window);           // Destroy the window
    break; 
  }
}
?>

Create Form

I have not provided details for a control’s position it’s your choice. Frame sizes are important they must match our images these are 20x12 pixels.

Before creating a form it is best to create a new folder that will contain the resulting form (refered to as a project). Create a new folder named my_project (or any other name) in folder C:\us_wb

Start form editor by running C:\us_wb\wb\form_editor\Run_form_editor.bat

  • Add a PushButton change ID to IDC_BUTTONRED1 change caption to Red 1
  • Create a second button change ID to IDC_BUTTONRED2 change caption to Red 2 Move this button just below the first button


  • Create a Frame change ID to IDC_FRAMERED1 delete the caption. In the styles select (check) the image box. Change the width to 20 and height to 12 . Move the frame to the right of button 1.
  • Create a Frame change ID to IDC_FRAMGREEN1 delete the caption. In the styles select (check) the image box. Change the width to 20 and height to 12 . Move the frame to the right of button 1 (left and top values identical to the above frame).


  • Create a Frame change ID to IDC_FRAMERED2 delete the caption. In the styles select (check) the image box. Change the width to 20 and height to 12 . Move the frame to the right of button 2.
  • Create a Frame change ID to IDC_FRAMGREEN2 delete the caption. In the styles select (check) the image box. Change the width to 20 and height to 12 . Move the

frame to the right of button 2 (left and top values identical to the above frame).

  • Resize the application window to so the buttons and frame are in the enter of the window.

Save the project with name my.prj to folder my_proj as follows

  • Top meun, select File > Save Project as
  • Navigate to folder my_project
  • Eenter my.prj
  • Click save
  • Exit form editor, select File > Exit

Exported file

The form editor automatically exports a PHP file corresponding to the form component layout.

This file can be found in our project folder.

In this example it is named my.form.php and has the following content

<?php

/*******************************************************************************

WINBINDER - form editor PHP file (generated automatically)

*******************************************************************************/

// Control identifiers

if(!defined('IDC_BUTTONRED1')) define('IDC_BUTTONRED1', 1);
if(!defined('IDC_BUTTONRED2')) define('IDC_BUTTONRED2', 2);
if(!defined('IDC_FRAMERED1')) define('IDC_FRAMERED1', 3);
if(!defined('IDC_FRAMEGREEN1')) define('IDC_FRAMEGREEN1', 4);
if(!defined('IDC_FRAMERED2')) define('IDC_FRAMERED2', 5);
if(!defined('IDC_FRAMEGREEN2')) define('IDC_FRAMEGREEN2', 6);

// Create window

$mainwin = wb_create_window(null, AppWindow, '(Empty Form)', WBC_CENTER, WBC_CENTER, 195, 141, 0x00000000, 0);

// Insert controls

wb_create_control($mainwin, PushButton, 'Red 1', 20, 20, 90, 25, IDC_BUTTONRED1, 0x00000000, 0, 0);
wb_create_control($mainwin, PushButton, 'Red 2', 20, 60, 90, 25, IDC_BUTTONRED2, 0x00000000, 0, 0);
wb_create_control($mainwin, Frame, '', 141, 23, 20, 12, IDC_FRAMERED1, 0x00000004, 0, 0);
wb_create_control($mainwin, Frame, '', 141, 23, 20, 12, IDC_FRAMEGREEN1, 0x00000004, 0, 0);
wb_create_control($mainwin, Frame, '', 141, 63, 20, 12, IDC_FRAMERED2, 0x00000004, 0, 0);
wb_create_control($mainwin, Frame, '', 141, 63, 20, 12, IDC_FRAMEGREEN2, 0x00000004, 0, 0);

// End controls

?>

Copy and paste

At this stage we can start building our application.

Copy images files (uslogo.ico, red.bmp and green.bmp) from folder C:\us_wb\wb\us_tutorial to folder C:\us_wb\my_app.

  • Open files C:\us_wb\my_app\z_basic.phpw and C:\us_wb\my_project\my.form.php in a text editor.
  • From my.form.php copy “Control identifiers” section and past in to z_basic.phpw under the Constants section.
  • From my.form.php copy “Insert controls” section and past in to z_basic.phpw under the “2) Create controls for the main window” section.
  • In z_basic.phpw change wb_create_window to have the same width and height as that in my.form.php.

Assign Images

Use the following code to assign images to the frames. Place code at end of section “2) Create controls for the main window”

// Assign images to frames
wb_set_image(wb_get_control($mainwin, IDC_FRAMERED1),'red.bmp', NOCOLOR);    
wb_set_image(wb_get_control($mainwin, IDC_FRAMEGREEN1),'green.bmp', NOCOLOR); 
wb_set_image(wb_get_control($mainwin, IDC_FRAMERED2),  'red.bmp', NOCOLOR);   
wb_set_image(wb_get_control($mainwin, IDC_FRAMEGREEN2),'green.bmp', NOCOLOR); 


Add a logo image to the application window.

//=== 3) Assign handler function to the main window  --------------------------
wb_set_handler($mainwin, "process_main");
  wb_set_image($mainwin, "uslogo.ico");  // Add logo

Test

  • Run C:\us_wb\my_app\z_basic.bat
  • Application shown on right.
  • Currently buttons do nothing code to be added later.

Summary

That completes form editor introduction you will appreciate how useful it is when you work with a larger application.

If you need to add additional controls or move the existing controls around open your project file in form editor make the changes and transfer these to your application. That really does save time.

Before looking at PHC-Win next page covers adding functionality to the buttons. This functionality is spread across several files providing PHC-Win with more than a single file to process.
