Hi,

I am writing a Media player application using GTK. I am using horizontal scale for volume slider.

I have writtten this code:

GtkWidget* hscale;
hscale = gtk_hscale_new_with_range(0.0, 100, 1.0);
gtk_widget_set_size_request(hscale, 80, -1);
gtk_scale_set_draw_value(GTK_SCALE(hscale), FALSE);
gtk_range_set_inverted(GTK_RANGE(hscale), TRUE);

It would graphically look like:

|------------------------------------|------||

<---------------------------------->

Now i want to show the region in the slider ass mentioned by arrow to be filled so that when i open the player, the volume slider is filled by default and when i drag it from right-to-left, it looks like i am decreasing the volume.

Can anybody tell me a API to do that??? I have searched that and applied 1-2 techniques, but nothing is working.

Any help in this regard would be great...

Thanks in advance.

cheers..
Jamie

Media Player using GStreamer

Download this book example code and extract them. Look code for Chapter 11. You can see very easily how to use " GtkHScale widget " in a real Media Player using GStreamer project.
