Introduction

KGtk is a quick-n-dirty HACK to allow some Gtk2, and Gtk3, applications to use KDE Frameworks 5 file dialogs.

KGtk is composed of the following pieces:

1. An application called kdialogd5. This is the KDE app that will show the file selector.
2. LD_PRELOAD libraries that are used to override the Gtk2 and Gtk3 file dialogs.

If you start an application using the following command: kgtk-wrapper gimp

...the the following occurs:

1. kgtk-wrapper determines whether the application is a Gtk2 or Gtk3 application. It then sets the LD_PRELOAD environment variable to point to the approriate KGtk library.
2. When 'gimp' now tries to open a file dialog, the KGtk library intercepts this, and asks kdialogd to open a file dialog instead.

There will only ever be one instance of kdialogd, and all apps communicate with the same instance - and it termiantes itself 30 seconds after the last app has disconnected. This timeout can be changed by editing kdialogdrc and setting/changing

[General]
Timeout=10

Installation

As of v0.9.1, kgtk uses CMake in place of autotools.

This is accomplished as follows:

1. mkdir build
2. cd build
3. cmake .. -DCMAKE_INSTALL_PREFIX=/usr
4. make
5. sudo make install

• For 64 bit systems, also append -DLIB_SUFFIX=64

Notes

The library has been tested with the following applications:
