I would like to make a GUI that is not a standard rectangle, but instead is whatever polgon/shape I would like it to be.
A good example of an app that does this would be winamp.
It seems that all GUI programming is related to using tools similar to Visual C++, with buttoms and widgets.
How does one go about making a custom gui like this?
I am versed in C++ but I would not mind learning a new language.
I would like an easy way to draw a polygon from a load of xyz points that should be on its surface. Can someone help? Ideally using java 3D but I could use something else. Quick and dirty is fine its just to see a shape. I haven't really done any 3D graphics programming.
View 8 Replies View Relatedi am working on developing a very minimalistic os based on a striped down linux kernel and for the user interface ive come up with a bunch of custom graphics and such and then i was confronted with the problem of what window manager do i use....
basically my concept for the ui is windows that only open fullscreen (so no resizing, minimizing, moving) btu when you want to change threw applications it displays everything in a coverflow style and im planning on using the Qt toolkit for the interface itself and basing alot of it on web technology's.
I've been researching on how to fully decorate the window borders and toolbars but I can't seem to get a clear as day answer. The threads I've found that have plenty of information are quite old (usually 2006), and others lead to things I already had tested with, such as Gnome Color Chooser. GCC was very nice, but it didn't really do everything I wanted. For one, I could only change the colors of the Main Menu, but not other menus such as the menus within Firefox (those are still grey with white letters and an orange highlight when hovering). It also wouldn't change the colors for the factory clock in the taskbar without messing up a bunch of other things. The list goes on.
What's even more confusing and the reason why I haven't begun is the following. Some people mention GTK+2, others Metacity, and others COmpiz and others Emerald. I know what COmpiz and Emerald are, but I don't understand how they're related (or unrelated) to the other 2 terms. Some threads mention how Emerald offers better functions than the rest, others just talk about editing Metacity themes. In short, I'm completely lost in the terminology. I do understand that the editing to get the exact look I want has to be done by hand, and I'm willing to do that. It's a bit pointless though if I'm stuck with the terminology I've mentioned. I want to know which themes I can search and be able to edit them to the looks I want.

I'm building an RPM that requires adding a cron job into a user's(service account) crontab...from what I see in the manpages, this isn't possible, as the only viable option is to replace the crontab entries already there for previous scripts being run. Either way, as an example I've found I can make it work by directly modifying the crontab file using:
Code:
echo "* * * * * /bin/ls -la ~/ >> ~/ls.log" >> /var/spool/cron/userName
I'd just like to know, is there any MAJOR issues with modifying a the crontabs like this? This is running on a Redhat Enterprise Linux server by the way.

My issue is that I'm not sure how setup all the Environment Variables that I need on the remote machine. I was able to write all the environment variables/values (NAME=VALUE) that I needed to a file and place on a shared file server (prog.environment). I thought the best way to approach this would be to write my own utility (custom.shell) that would interpret the environment file and then execute the desired command.

I am trying to create a custom service to manage a minecraft server what runs in a screen session (this is to allow easy console access as opposed to running it as a nohup background process). I am hitting two main issues with this script so far and wondering if anybody is able to shed some light on it, considering I am far from the greatest BASH scripter on Earth.
The issues are related to start and stop. the first issue with start is there is a command run "screen -dmS minecraft java -Xms1024M -Xmx1024M -jar /minecraft/minecraft.jar nogui" what doesn't appear to work, however when run from console (copy and pasted) this command seems to run perfectly. I am uncertain as to why this is not working within the script. Also if run from a script in /minecraft it also appears to work but in the minecraftd script I have created at /etc/init.d it does not work. I think the issue might be related to the location but am not certain on it, nor how to resolve it.
the second issue with stop is that it works sometimes but at other times it does not, overall it seems to work about 30~50% of the time. When it works it passes a couple of disconnection messages to the screen session and then gives the stop command (the command to gracefully terminate the minecraft server). It seems to work more often when using screen that I attach to the minecraft session while it is running but really not sure if this is an issue with my scripting or an issue with how I am passing things to screen.
The full code in /etc/init.d/minecraftd is below
Code:

i have written a bash script to convert flv files (e.g. videos) to xvid to be played on my dvd player. the conversion is not really the issue, as it works. what i am dealing with now are 2 problems i have not found a good workarouond:
1. surpressing the shell output of mencoder completely ( i do not want to see all the mencoder messages). this i have only solved to a certain extend.
2. i want to create a progress bar. this one i have not yet cracked.
the script:
code:
#!/bin/bash
## settings
v_bitrate=768
video_opts="-ovc xvid -xvidencopts bitrate=$v_bitrate:autoaspect"
audio_opts="-oac mp3lame -lameopts fast:preset=standard"
store_dir=./converted_files .....
#start the script
main_menu
1. mencoder output: using /dev/null works more or less. for example: if mencoder detects a double frame while converting, a message is still printed on the bash screen
2. progressbar: i have no clue yet on how to do this. any link or tip is welcome.
my goal is something like this:

Just spent three whole days barking up the wrong tree, solving Fedora 11 and Fedora 12 boot failures because the correct hypothesis was illogical: installation did not update/modify the initrd.
The first couple of times I installed Fedora 11 on the HighPoint Technologies RocketRaid 2640x4, the installation inserted my "custom" driver module (rr26xx) into the initrd, permanently, so that the system booted off the controller card for which the custom driver was inserted. (I yelled about this success in this thread: [url]
My most recent installs of BOTH F11 and F12 on the RocketRaid failed to properly set up the boot. It turns out that the "rr2640" module I "slipstreamed" into the installation process was *NOT* permanently added to the initrd by anaconda. (F12 gave me "no root device found boot has failed, sleeping forever", on boot; F11 hung also, without such error, I presume, during the init script execution). Because of limited resources and time, I only know for sure the module was missing from the F11 initrd, and am ASSUMING the same was the case with F12.
The only difference between the successful installs and the ones with failed boot is that the successful installs were made on a single-drive (JBOD) mode on the controller; whereas, the failed ones were placed on RAID 5. But, AFAIK, the created logical device for the card is "/dev/sda", in both cases, and the kernel can not distinguish between the two cases (or can it?). Thus, the inconsistency cost me a lot of time, and is still inexplicable to me.
Question: What is the best way to deal with custom drivers, today? There are custom spins, and many tools, like isomaster. Stupid question: Is there a way to modify the initrd inside an installer ISO -- be it for CD/DVD/USBboot drive -- beefing the init RAM disk with whatever modules you'd like, for the boot process (using, say, isomaster)?
And what makes anaconda understand that a module must be added to the initrd ? How can one force anaconda to do so?
How does moving to dracut as the initrd tool affect any/all of the above?
I am having trouble writing an Xlib application that displays a window. The most frustrating thing is that I've written applications like this before, and never had any problems. For some reason I cannot get this program to work properly. I'm running KDE and when I launch the program, a "button" for the application will appear on the application panel, however, no window will display. It is possible to right click on the panel button and select the Close item which will successfully close the window.
The following is source code that when built will exhibit the behaviour described above code...
Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system. A code snippet/hint for the pop-up window then?

View 4 Replies View RelatedI have a toplevel window that I want to place depending on another toplevel window. I use gtk_window_move(widget, x, y); At startup this function is called several times and y is changed ones from 412 to 413 and x is always 0(checked with gdb in netbeans). The window gets placed at x=10 and y=400 or so. If I do not use variables but pure ints for x and y it gets placed correctly even if its the same values. I suspect that my window manager notice this change of y and place the widget for me. Is this correct and how do I tell the WM not to do so?
This change of y is due to window size is just a local size and not the correct one as in X. Can i force uppdates from X to the local cache?

View 8 Replies View RelatedI am trying to write a small gtk+-2 program to display whatever image it is given and I was wondering if anyone out there has done something similar. I am not too familiar with writing programs for gtk and its been a while since I've fiddled with C. I went over the tutorial for gtk and it seams pretty easy to get a window to display, but I do not see anything that refers to loading an image or displaying it in the window. I am wondering if this can be done purely with gtk or will I need to use some type of image library like imlib2?

View 2 Replies View RelatedUsually the menu bar, and menus, are displayed within the applications main window. With a small screen this obviously wastes space so my idea is to reserve a location, small square space probably on a corner, on the screen that when clicked it will pop out the current selected applications menu, allow selection, and then disappear again. The application itself would look fullscreen, or if windowed will still not have a menu bar but access available via the "square."
Likewise instead of the usual task bar and "applications/places/system" menus (ala, ubuntu) a second square would be reserved which would pop-out and show the running tasks, followed by the menus, and allow selection, then disappear. Is this possible with GTK+ as it stands, as I'm guessing that by default everything must be contained within an applications main window?
Although having said that, gimp allows the tool windows to be external to the edited document, so perhaps it would be possible to make the menu bar into a toolbox? I guess the difficult problem would be how to make the currently selected applications "tool square" be on top when there could be multiple applications running. The "tool square" and "task/menu square" could be transparent (maybe just an outline) so that although always there they wouldn't hide any underlying windows/programs/etc.
Basically the idea is to get rid of wasted screen, in ubuntu (on gtk/gnome) a minimum of 5 "bars" is wasted screen real-estate:- 1, Running aplications: 2, Ubuntu's main menu bar: 3, Applications status bar: 4, Applications menu bar: 5, Applications description (min/max/close) bar. Take all the above and replace it with two clickable, potentially invisible, squares say where the default "hide all windows" and "deleted trashcan" icons currently reside.
It's been a while since I did any kind of graphics programming, but I would like to start learning how to do graphics stuff in *nix. I started reading the GTK+ 2.0 Tutorial, but a) I've only been able to write a small "Hello World" program, and that tested my patience, and b) I'm not seeing anything which allows you to plot a pixel directly. Back before I migrated to Linux, I used the Windows GDI SetPixel() function for plotting pixels sequentially (this was for a small fractal generator). Mostly what I'm asking is if there's any kind of equivalent function in *nix graphics APIs? GTK+? Would I have to deal with SDL/OpenGL?
