Re: Status Indication GUI development using GTK++

[Adeel Malik <adeelmalik78 yahoo com>]

Hi Larry,
            Thnaks for your reply.
As I would be starting the GTK+ development on Fedora Core 6 Linux machine, could please suggest how to 
install GTK+ on aforesaid machine as I haven't done any software installation on Linux lately and also I 
couldn't find step-by-step installation instructions in gtk+ tutorial.
Also I have couple of questions.
1. Is it possible if I could create the image on a windows machine as a JPEG file and then set those image 
files to correspond to gtk image widgets after copying the aforesaid jpeg files to the linux machine from the 
windows machine or I 'ld have to create the images on the linux machine.
2. In the tutorial I couldn't find the reference code to load images as gdkimages and then using 
gtk_image_set_image. Is there any documentation available on-line that specifically talks about the 
creation/manipulation of image objects in GTK+.
 
Thanks for your help,
Adeel

1. read gtk+ tutorial
2. make window
4. add hbox to window
5. add two gtkImage widgets to the hbox
6. create 4 images: dull red (red light off), bright red (red light on),
dull green, bright green
7. load 4 images as gdkImage's
8. use gtk_image_set_image to set the image widgets to the two
gdkImage's you want
9. make a function that swaps the state, call this from your other code
as necessary

There is pretty good documentation out there.  Your two best friends
will be google and devhelp(an application for gtk+ and related
documentation).  If you don't have devhelp, you can search
library.gnome.org, but devhelp is much more convenient, so I would
recommend taking the time to install it.
