Hi everybody,
I learn to create hello-javascript plasmoid by javascript. I do follow these step in :http://techbase.kde.org/Development/Tutorials/Plasma/JavaScript/GettingStarted.
My tree directory is:

Code: Select all

hello-javascript/
hello-javascript/content/
hello-javascript/metadata.desktop
hello-javascript/content/code/
hello-javascript/content/code/main.js

But when I try:

Code: Select all

plasmoidviewer hello-javascript

The problem is: Could not find requested component: hello-javascript

My system is KDE 4.4, I installed: plasma-addons, plasma-addons-devel, qtscript.

Please, help me to fix this problem!

Please try running "kbuildsycoca" and post the contents of metadata.desktop please.
Also, have you installed this tree into the appropriate directory under $HOME? ( using plasmapkg )

Hi bcooksley,
Thank you for reply.
My system hasn't got kbuildsycoca, output of kbuildsycoca4 is:

Code: Select all

kbuildsycoca4 running...
kbuildsycoca4(3045)/kdecore (services) KServicePrivate::init: The desktop entry file  "/usr/share/applications/YaST2/groups/apparmor.desktop"  has Type= "Application"  but no Exec line

kbuildsycoca4(3045) KBuildServiceFactory::createEntry: Invalid Service :  "/usr/share/applications/YaST2/groups/apparmor.desktop"
kbuildsycoca4(3045) parseLayoutNode: The menu spec file contains a Layout or DefaultLayout tag without the mandatory Merge tag inside. Please fix your file.

My metadata.desktop is:

Code: Select all

I haven't installed using plasmapkg because in tutorial, I read that "you can testing without installing by run plasmoidviewer"

However, I try to install by plasmapkg, the result does not change: "Could not find..."

I gather you are following http://techbase.kde.org/Development/Tut ... ingStarted

If so, are you passing the full path to your Plasmoid ( ie. where the folder where metadata.desktop is ) to plasmoidviewer?

I read and did follow the tutorial. In my tree directory I post in #1, I change to hello-javascript directory for running plasmoidviewer

You need to run "plasmoidviewer ." in this case. Make sure to keep the "." in the command.

You only use the name if you have installed it. As you haven't, you need to supply a path, which the "." will (it supplies the current directory)

Oopp, it's my fault, I always try `plasmoidviewer hello-javascript`
Many thanks to you
It's exactly problem with me. I try `plasmoidviewer .` and it 's solved.
