You can find documentation on Customer Connection about branding homepage tabs in Enterprise Portal. But, what about changing the tabs that separate pages in a multi-page component? If you've been through a few PeopleTools upgrades, you've noticed that PeopleSoft occasionally changes the tab colors and tab design, so it must be possible... right? If you save one of those tab images, you will notice that tab images follow a naming convention. Component tabs are called level 2 tabs and are prefixed with PT_TAB2. You will also notice that App Designer contains PT_TAB3 images. I'm not sure where these are used.
Component tabs are comprised of 7 images, all of them ending in a hexidecimal color. The seven images are
BBBBBB represents the hexadecimal inactive tab background color and
CCCCCC represents the hexadecimal active tab background color. If you haven't changed your default stylesheet, then
PTSTYLEDEF_DARKBLUE contains the definition for your active and inactive tab colors. The style classes are
PSINACTIVETAB. If you change the background color of either of these classes, then be sure you have all 7 new images in your database with matching color names. If you don't then your app server session will crash. It appears that the C++ code on the app server determines which image to choose based on the background colors of
PSINACTIVETAB (hence the naming convention). Note also that the images with AI and IA prefixes list the inactive color before the active color.
Level 3 tabs follow the same conventions as level 2 tabs except for the addition of the PT_TAB3MIXBBBBBB image which represents the middle of 2 inactive tabs.
If you choose to change your tab colors to something that isn't delivered, be sure to upload all 15 images (level 2 and level 3). Otherwise, your app server session will crash each time you navigate to a component.
Update Tuesday, March 4th, 2008
While finishing up a branding project, I noticed that the 2 in PT_TAB2 does not describe the level, but the row. A component's tab set is actually comprised of 3 rows of images, PT_TAB1, PT_TAB2, and PT_TAB3. PT_TAB3 images make up the bottom row of the tabs. You must create a new PT_TAB3 image for your new background color using the naming conventions above. PT_TAB1 images are shared by all background colors, so you do not need to create new PT_TAB1 images for each background color combination.
