Programming :: Creating Gnome Panel Applet?
Mar 12, 2010
I need to be pointed in the right direction on how to do this project. I simply want a gnome panel applet that will run constantly and, when clicked, will display an IM style list of I.P. addresses that are active on the network I am currently connected to. It should be able to have a configuration menu that will allow the user to specify a subnet mask, and frequency of scan. I am looking for something that will return something similar to the output of:
Code:
nmap -sP xxx.xxx.xxx.xxx-xxx
My question is: What language should I learn to make this happen, and is anyone willing to mentor me through the process?

Seeing this on two systems that went through F13-F14 upgrade.
version: gnome-applets-2.32.0-1.fc14.x86_64
symptom: via right click on a gnome panel, perform "add to panel" and choose Dwell Click.
Gnome panel bites the dust with SIGSEGV at this point, restarts, and then you've got dwell click on the panel.
Anyone else seeing this, and better yet, have a solution?

I'd like to put an applet exactly in the middle of my Gnome Panel, I can't do it manually as the applet size varies so I need a way to put it in the middle always. The applet is dockbarX (a window list) so when I open or close a window the size of the applet changes and then it's not in the middle. Here you are an screenshot of what I'm talking about:[URL]..

I'm experiencing a strange problem with GNOME Clock on Fedora 13. When the applet is in the bottom panel, and I click on the clock, the popup display appears at the top of the screen rather than at the bottom of the screen (above the bottom panel) as would be expected. Worse, the display appears higher than would be expected had the clock been on the top panel, meaning the display is cutoff (ie, the display goes off the top of the screen). I've tried playing with my .gconf files, and removing and re-adding the GNOME Clock applet, but nothing has worked. I'm not sure if this is a weird quirk particular to my settings, or a more general bug; can readers here check to see if the behavior I've described occurs if the Clock applet is added to the bottom panel?

I want the mail icon (indicator applet) in the panel to open thunderbird when I click mail, and when I click "new message" that tbird message opens. I've already got the notification going, and I have removed evolution.

My weather applet on the gnome panel disappeared and I cannot add it back i.e. when I go to "add to panel" and choose to add "Weather report" nothing happens.

I frequently travel between San Diego and Boston. I am able to add "Locations" to Gnome's Clock applet, which seems like it should take care of time zone information (see attached screenshot). However, I can't figure out how to set one (or the other) as my current location so that it will update my time zone information.

Do you know the GNOME Panel applet that is terminating running applications after clicking on them with the cursor and confirming the action with a Yes/No dialogue?I know about xkill, but it is not satisfying due to it has not confirmation dialogue.Instead, I would like to use xprop and kill and zenity

I'm having a weird issue with Lucid. On startup the power/user switcher applet doesn't load correctly, instead I see the me menu applet twice. I don't think I'm explaining this very well, so here's a screenshot.

After killing gnome-panel, this corrects itself.

I have Ubuntu 10.10 on e-machine T-1221 I can shut down the machine using :
sudo shutdown -h from terminal
I can shutdown using powerbutton on case. I can't use the applet indicator powerbutton in root account, but, I can use the command under "System-->-Shutdown" in root account, but I don't see "System-->-Shutdown" in users account. Is there a way to add it ? I installed Debian 6.0 Squeeze on my Acer Aspire 3620 Laptop it works just fine and has the same Gnome Desktop. The only thing different is that there is no powerbutton available thru Gnome applets, only the command on menu under" Sytem-->-Shutdown", which I'm fine with on this machine.
These are the things I tried on emachine T-1221
I tried "acpi=force"
I tried "noacpi"
I tried "noacpi nolapic"
I read the bug reports it stated that on live-cd there was only suspend and hibernate. There is no shutdown or reboot. I tried: "#start acpi", it closed with errors. It said that Ubuntu uses upstart. Is there a script which you can add to power button to add the shutdown.? Really I don't necessarily need powerbutton, I think the work around would be adding the command to "System-->-Menu.

I have a suspicion that this is easily fixed, however a good google (and this forum) hammering having turned up the fix. So I probably have the wrong search criteria, My Gnome Applet for switching CPU Frequency Scaling has 'disappeared' and is not listed in the the Add to Panel.. list of applets.

I cant use the option "export" from the VPN settings in the Gnome Network Manager, when I tried to export a popup says "Unknown error"This happend also in 11.3 and now in 11.4, so it is a nm-applet problema I think... Is there any other way to export my VPN connections?

I need the steps to troubleshoot this:
If I:
1. Add drawer(s) on the gnome panel
2. add items to one or more of those drawers
3. reboot then:
1. all empty drawers can operate normally
2. drawers that have stuff in it cannot be opened.

Is it possible to install Gnome-panel in Xfce? I'd like to completely replace xfce-panel with gnome-panel. It is possible the other way round so maybe this way too?
[url]
I tried xfce4-XfApplet-plugin but it doesn't work the way I would like to.

I have such an annoying problem that I really don't know how to fix! Basically for some reason the nm-applet icon just doesn't sit in the panel anymore, but it's floating on the desktop as a normal application. Restarting/reinstalling it doesn't solve the problem, it's still out of the panel. With any theme I use. It's a pretty fresh installation of Ubuntu 10.10 on a MacBook Pro, so there are no particular customizations. The only workaround I found is installing wicd, but I'm really not familiar with it and want to get rid of it.

So I just updated my IdeaPad to Natty and played around with Unity. The performane was absolutely unbearable so I installed Unity2D from the software center. Now when I start the session everything seems to be fine at first. Whenever I move the mouse over the panel though it seems to switch to my old gnome-panel from the "Classic" session (with some missing icons). When I move the mouse over that panel again it switches back to the Unity panel style. What is going on? Can I fix this somehow? I will have to use the classic session until I get a working consistent behavior

Regarding the gnome-panel in Ubuntu (64 bit).... I discovered some time ago that I wasn't the only one who routinely (every login) had their gnome-panel appear butchered, for which Alt-F2 then 'killall gnome-panel' would easily fix.
Having become impatient with this over the past 8 months, I decided I would automate the process and so cofiguring the startup applications seemed like a perfectly logical choice to me. Turns out I was wrong. After adding 'killall gnome-panel' to the startup applications not only does the panel fail to load altogether now, but Alt-F2 doesn't even work.
I tried Ctl-Alt-F1 and working with the graphics-free mode thinking I could somehow navigate to the startup apps config file and edit it, but I don't know where it is or how to edit it without logging in as root and I certainly don't know of any 'root password'.

how to get a globalmenu applet in my top panel?
I checked the packman repository ... not there. I tried to build the tarball from ...
Downloads - gnome2-globalmenu - Project Hosting on Google Code
... but got hung up when sudo ./configure replied: test for libpanelapplet-2.0 and libnotify failed. (--without-gnome-panel to disable)
the error did not go away when i installed libnotify-devel (and libpanel-applet-2-0 was already plugged int).

In the process of removing all hints of KDE from my system I accidentally uninstalled on of my panel applets.It is the one that says the users full login name and allows you to control gwibber status and empathy availability.I know it's kinda OCD but my desktop looks weird without it.

I had too many issues with 10.04 so reinstalled 9.10 for now.In the process of customizing the panel, I accidentally deleted the network and sound icons and there isn't any option I can find in the menu to restore it. How do I go about getting those back?

When I installed 10.04, I got rid of the messenger applet from the panel at the top since I always used webmail. I found a way to have the messenger applet automatically check and display new emails, but now I don't know how to add the applet back. Its icon looked like an envelope. I've tried the add to panel command, but don't see that one listed.

It showed up once I upgraded to Lucid. The inhibit applet keeps disappearing from the panel. It doesn't matter where I place it, if it's locked in place, or what panel I've placed it on; it will be there, but then disappear once I reboot the computer and log back in to the desktop. It shows as an empty space where the icon used to be; right clicking the blank space gives me the standard context menu for the panel instead of the context menu for the inhibit applet. The only way I can get the icon to reappear is if I go to the panel properties and fidget around with the Expand and Hide Buttons options. Does anyone have this same problem?

I installed Sensors Applet & hddtemp. Installation was smooth, all of my devices were automatically detected and all seemed good.Then I restart the computer, and when everything comes back up, the processor, MB, and GPU are all working (showing a temperature) but none of the (6) hard drives are showing a temperature. After fiddling around with it I found that removing the applet from the panel, and then adding it back again fixes the problem. But then the next time I restart the computer it breaks again.

Basically, I chose to give Ubuntu Studio another try (after it had annoyed me with it's lack of wifi), but the problem is that there's no network manager applet in the indicator area (i added it in the top right, the panel's set up as it would be in normal Ubuntu)Using Wifi Radar, i think that the wifi card works in the preempt kernel, it's just that i don't want to use Wifi Radar all the time, can prove to be annoying.
When i start nm-applet, a small space opens up in the indicator applet. I'm not sure if that's something important.Has someone managed to get this to work? (i've installed network-manager and network-manager-applet)

I was trying to get suspend and hibernate on my shutdown menu and I removed it from the panel with the intention of adding it back, hopefully with the suspend and hibernate choices on it.
How do I get the shutdown menu back on the panel?
If I don';t get it back then how do I shut down?

the nm-applet seems to have disappeared from the top panel, whenever I run the command it gives me the output:
Code:
** Message: applet now removed from the notification area
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** Message: applet now embedded in the notification area
I have tried the --sm-disable parameter but that doesn't help ether
