Re: changing colour of widget
Hello Mahesh, I did not know that you use the old version. Actually, Gnome VFS is deprecated, but on your Linux it should be still available. This library has a similar monitor: https://developer.gnome.org/gnome-vfs/stable/gnome-vfs-2.0-gnome-vfs-monitor.htmlProbably, this should suit you the most. There is also another library that you can try to use: http://en.wikipedia.org/wiki/Inotify If you do not want to add additional libraries (I assume there are more solutions like proposed above), you can write a custom function to get information about the file in the main loop or in a separate thread. If the information, such as changed date and size, changes, you can send a custom event.

Re: changing colour of widget
Thanks Vest V for reply I can able to draw circles using GtkDrawingArea and cairo but is there any alternative to GIO as I have to use CentOS-5.3 (glib version 2.10) and I think GIO is not supported in this version OR from where do I install GIO library From: Vest V.

Hello Mahesh, It depends on which approach you want to use: draw LEDs manually, or display images. The first possible widget is GtkDrawingArea: https://developer.gnome.org/gtk3/3.2/GtkDrawingArea.html, the second is GtkImage: https://developer.gnome.org/gtk3/3.2/GtkImage.html Regarding the event: probably you need GIO library (especially the GFileMonitor: https://developer.gnome.org/gio/unstable/GFileMonitor.html) Kind regards, Vlad On Thu, Sep 26, 2013 at 12:17 PM, Mahesh Chaudhari < mahesh.chaudh...@ymail.com> wrote: > Hi List, > I am very new to GTK+ programming and got a task of developing user > interface (GUI) to one of our embedded board > I went through basics of GTK searching for any widget that could represent > on board LEDs, which can glows (basically changes colour) > Also, is it possible to generate an event whenever file is updated instead > of user (mouse clicks, keyboard press) > > > Any Help > ___ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list > ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
changing colour of widget
Hi List, I am very new to GTK+ programming and got a task of developing user interface (GUI) to one of our embedded board I went through basics of GTK searching for any widget that could represent on board LEDs, which can glows (basically changes colour) Also, is it possible to generate an event whenever file is updated instead of user (mouse clicks, keyboard press) Any Help ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
