probelm in custom tab.. need help

[poojs]

hi i have to create a custom tab for which i am using below link:
http://wiki.forum.nokia.com/index.php/Custom_tabs

i have used CreateAndShowTabsL() in appui class and called this method from ConstructL()
but it didnot work out :( nothing displayed as tab.

[skumar_rao]

have you put the icons properly ?

[poojs]

yes i have put all the icons properly ... is it ok that i have used everything in Appui class.

[symbianyucca]

Are you also having some other containers constructed in your appUi class ?, could it be that they are actually drawn on top of the tab container ?, anyway, Depending on how you would want to use the Tabs, it also might be a good idea to actually have the tab-control as an control in the container that you are showing the items according to the Tab, it might make it a bit easier to actually handle the area where each controls are..

Anyway, I would suggest also debugging it in a emulator to see that all icons are loaded correctly, and that the areas set for different containers are ok.

sorry for the late replying as i was busy in other things.
yes i have used other containers too. i have created 4 tabs but only the one tab is showing while i am running it. and attached is the screen-shot how it looks like.
this time i have commented the images in custom tab.
below is the Appui file:

#include "CustomTabControl.h";

It is a custom control with complete source code, you could simply scatter some breakpoints and check its control flow.

[poojs]

i tried it :( but it only shows 0 index's text on the top of the screen

[symbianyucca]

Then you just need to debug it a bit more and try understanding what it is doing. As it is custom control that you have source codes for, you basically can check excatly what it does as well as you can modify it as you wish.

[poojs]

n 1 more error is there
undefined identifier 'KN_UI_LOG_TYPE_DEBUG'
in line

KN_UI_LOG((KN_UI_LOG_TYPE_DEBUG,"CCustomTabControl::OfferKeyEventL\n"));

[symbianyucca]

that sounds some custom definition, so check the source where you got the example, and if you can not find that one, then try commenting the whole line out.

[amitkankani]

well it looks like to be used for LOG... you can comment it .... were u able to complete your implementation ....
