PHP WinBinder 2: WinBinder portable

UniServer 5-Nano PHP WinBinder 2.

WinBinder Part 2

Introduction

PHP is an excellent scripting language, primarily designed for dynamic web sites. It also contains a command line interface, which you run from a command window. Although powerful, it lacks a friendly user interface. The WinBinder project addresses 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 WinBinder's capabilities, run the examples in the 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 convenience. (See PHC-win on how to create executables).

Run manytests_main.bat which 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 the batch file Run_form_editor.bat. This runs the form editor. You will see three floating windows as 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 controls, 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 that 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 using 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 which you can use either directly or cut and paste the 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 its corresponding image. Several small files are used to simulate a larger project and demonstrate PHC-Win capabilities.

Preliminary

Every application requires a main folder to store the files and resources.

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

The reason for choosing this location is one of portability. You can copy folder us_wb to a USB memory stick and take your entire project set with you.

Basic Windows app

Basic Windows 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. but it cannot find the folder php. This folder resides inside folder "wb" and 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 Windows app with corrected paths

Basic Windows app with 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. But 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 that can have the following IDs 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. That’s your choice. Frame sizes are important because 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 (referred 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 so the buttons and frame are in the center of the window. Save the project with name my.prj to folder my_proj as follows: Top menu, select File > Save Project as Navigate to folder my_project Enter 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 the 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, the 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.
