Basic PDF viewer using Custom Command Definition

[Grigory Filatov]

Hi there,

I would like to introduce a built-in PDF viewer for MiniGUI (demo source code included).

Here is the explanation.

💡 Summary

This application is a basic PDF viewer built using MiniGUI Extended. It allows users to open and view PDF documents inside a resizable window.

---

🔍 Purpose

To create a small desktop application using MiniGUI that allows the user to:

* Open a window titled "Embedded PDF Viewer"
* Click a button labeled "Open PDF"
* Select a PDF file from their system
* Display the selected PDF embedded within the application's window

---

🧩 Key Components

1. Custom Command Definition

   #command @ <row>,<col> PDFVIEWER <name> ...

   * This defines a custom command PDFVIEWER for embedding PDF viewing functionality using DefinePDFViewer() function.

2. Main() Function

   * Initializes the GUI window with:

     * A button labeled "Open PDF"
     * Event handlers for resizing the PDF viewer when the window is resized or maximized
   * Activates the window to show it to the user

3. ViewPDF() Function

   * Called when the "Open PDF" button is clicked
   * Prompts the user to select a .pdf file
   * Releases the existing PDF viewer if one exists
   * Creates a new PDF viewer embedded in the form with the selected file

Your feedback is welcome.

Regards,

Grigory

Hi Richard,

These  functions  will be included in the next version of MiniGUI along with the new command @ <row>,<col> PDFVIEWER <name> FILE <pdfname>.

Thank you for your attention.

Regards,

Grigory
