DisableGraphics / GifView

Simple and effective GIF viewer widget for GTKMM 3

MediaView

Simple and easy to use media viewing library for Gtkmm3

Installing the library

Dependencies

• gtkmm 3.0

Installing dependencies

Ubuntu

sudo apt-get install libgtkmm-3.0-dev

Arch Linux

sudo pacman -S gtkmm3

Fedora

sudo dnf install gtkmm30-devel

Compiling the library

git clone https://github.com/DisableGraphics/GifView.git
cd GifView
meson setup builddir
cd builddir
meson compile # You can change it for "ninja" if your meson doesn't have the compile command

Features

• ResImg: Automatically resizable static image widget. (It resizes automatically to fit the widget)
• GifView: GIF viewer that can be automatically resized, or set a maximum width and height.

Usage

• Since this library uses meson as its build system, you can use the subproject feature to import it into your project.
• You'll need to create a folder named "subprojects" in your project's root directory, and place the "mediaview" folder inside it.

Importing into a project

• Create a meson.build file and add this line to it:

mediaview_dep = dependency('mediaview', fallback: ['mediaview', 'mediaview_dep'])

• If you dont' know how to create a meson.build file, take a look at this tutorial
• Link the library to your executable:

executable('your_executable', 'your_executable.cpp', dependencies: mediaview_dep)

• Include the header file in your code:

#include <mediaview/mediaview.hpp>

Using the library

• This is an very basic example:

#include <gtkmm.h>
#include <mediaview/mediaview.hpp>

int main()
{
    //Create application
    Glib::RefPtr<Gtk::Application> app = Gtk::Application::create();
    //Create the window
    Gtk::Window window;
    //Create the gifview
    mv::GifView gifview = mv::GifView("/path/to/your/gif/file.gif");

    //Start the GIF
    gifview.start();

    //Add the gifview widget to the window
    window.add(gifview);
    //Show the window
    window.show_all();
    return app->run(window);
}

Why MediaView?

• MediaView is easy to use. Taking into account how convoluted Gtkmm can be for some things, this is an achievement.
• MediaView was made with automatic resizing in mind. Gtkmm isn't and you have to implement it yourself.

Notes

• Thread safety: Gtkmm is not thread safe. Since I'm using it as a base for my library, MediaView isn't thread safe too. I've found that ResImg in particular spits out exception messages instead of loading images when creating it inside a thread.
