Eclipse like tree icons changing - how to ?

In the Eclipse editor, the class explorer tree shows a set of icons and, when a class have some errors, it change to the same icon with a small red bullet at the bottom of the icon.
How can I implement this effect ?
I have done a two icons version of this effect, loading two images (the only difference between the image is the small red bullet). When a class becomes wrong, I change the Icon image.
Is there any other better approach ?

hello,
I would guess this is the same way Eclipse does it.
regards,
Tim

Icons changed - how do I change them back?

Hi guys,
Quick question - I had a problem while copying a file to a flash disk and Finder crashed (hard to believe, yes). So I force-quitted it but it didn't restart so I restarted the computer by holding down the power button. Then when I started it back up again it was fine except that the icon for my computer had changed. I can't specifically remember what it was before but it's definitely different now - it's an image of one of the old iMacs that were a half sphere with the screen on a chrome arm!
I presume that before it was a picture of my beatiful 24" intel iMac... but I can't for the life of me figure out how to get it back!
Does anyone know how?
Thanks!

Remember Tiger is not just for the latest models so it's fair enough
For other icons do a Google search on "icons for mac" there's hundreds+ some free
Before changing your drive icon
set up a new folder to hold the existing icon on (I have a folder just to hold folders with icons on)
select your HD and then Get Info - click on the icon (in Get Info) Command C to save to clipboard
select your new folder and then Get Info - click on the icon then Command V to replace the folder icon with the HD icon
then replace the HD icon

I am setting up ipads for use in an elementary, and I would like the "home screen" to be the apps, rather than the default with the chat, mail, etc icons. how do I change that?

Can anyone answer this question?

Depending on exactly what you want to do, there are a couple of ways of handling this. You may want to access teh user guide for some ideas: http://manuals.info.apple.com/en_US/ipad_user_guide.pdf
In particular, check the sections on Customizing iPad and Settings > Restrictions.

Hi kshieh
You can try two possible steps:-
1]Triple click the home button. You should get an accessibility menu.deselect the negative/black and white option.
2]Go to settings->General->accessibility->and deselect invert colours.
That should fix it

Hi,
you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

When I create a New Folder (on the desktop or in Finder), the system uses the Generic Document Icon instead of the Generic Folder Icon. How can I change this back?

When I create a New Folder (on the desktop or in Finder), the system uses the Generic Document Icon instead of the Generic Folder Icon. How can I change this back?
All of a sudden I noticed that most of the folders on my computer were no longer using the folder icon, but the generic document icon. I had to manually change back the icon being used by opening Get Info for each folder and copying and pasting the generic folder icon from some folders that remained unchanged. Now whenever I create a New Folder (right click -> "New Folder"), the icon that shows up is the generic document icon (white page with top right corner turned down). And I have to manually change it so it shows up as a folder in Finder or on my desktop. I don't know why or how this switch happened. All of the folders now on my computer look ok, but I need to change the default so when I create a New Folder it uses the correct icon.
I have also Forced Relaunch of my Finder and rebooted the system. I downloaded Candybar but am not sure what will fix anything, so I haven't proceeded.
Anyone know how I can do this? Thanks.

Anyone?

How to switch off 'Would you like to save changes?' message

Hello.
I am developing AddOn that has form of control type. This means some parameters can be specified (so editing mode must be on) but the data in database are never changed.
So standard message that SAP B1 displays ( 'Would you like to save changes?' ) when closing form is useless.
Please tell me how can I switch off this message.
Best regards,
Pawel.

Hi Pawel,
As A. Kerremans pointed out this is not possible, however if the item is not used to change the database you can set the AffectsFormMode property to false. This means that any change to the item will not change the form and B1 will not present you with message about saving the data (as it cannot detect that changes were made).
Good luck.
Best regards,
Pedro Magueija

See also this article about caret browsing: http://kb.mozillazine.org/Scrolling_with_arrow_keys_no_longer_works
In Firefox 3.6 and later versions you can disable the F7 shortcut that toggles caret browsing by setting the pref accessibility.browsewithcaret_shortcut.enabled to false.
To open the ''about:config'' page, type '''about:config''' in the location (address) bar and press the Enter key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

In that case, there may be a problem with your Finder preferences or window settings.
Try removing these files, then restarting:
~/Library/Preferences/com.apple.finder.plist
~/Desktop/.DS_Store
Let me know if you're not sure how to do that.

HT1473 When downloading a CD album, if it contains different artists, the album is split up into separate albums/icons. How do I get all songs into one album (just like the original CD)?

When downloading a CD album, if it contains different artists, the album is split up into separate albums/icons. How do I get all songs into one album (just like the original CD)?

Generally, in iTunes, all you need to do is fill in an appropriate Album Artist to keep things together. For older iPods each track from the same album should have the same artist, or be marked as a compilation where appropriate. For iOS devices you may need to go to Settings > Music > Group By Album Artist > On.
For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.

You have to create context attribute to store ICON in the same node which is binded to your tree or table control.

The personal hotspot is not an app or an icon; it is a setting. You must first have your carrier provision it, then you turn it on in settings. Most carriers charge extra for tethering.

Finally I realised that my new iPad2 is a DEMO UNIT. Thats why I can't control the appl icons. How can I turn this unit like a retail one?

Yes I can't. When I try to press and hold an icon, is doesn't wiggle. Also the label at the back of the box says "...white - Demo"
Well I guess that settles that then!
We just wanted to make sure that you did realize that you cannot delete the preinstalled apps and you can't download them again either, so if that was the basis on which you believed that you had a demo model, we were just double checking.
