Stacked canvas as a tab element

Question

I am working on a form say 'A'. In this form, I have a tabbed canvas 'B' with 4 tabs.
I created another stacked canvas 'C' on which there are elements from 3 different blocks. Now I need to make this stacked canvas as an element of tab2 in canvas 'B'. I.e., if the user clicks on the tab2 of canvasB, it should show the stacked canvas C below the tab.
How can I do this?
Thanks,
Chiru

Answer 1

It is not possible to define stacked canvas for a tab canvas.
To avoid such circumstances,
in pre-form, you write
HIDE_VIEW('STACKED_CANVAS');
SHOW_VIEW('TAB_CANVAS');
If tab canvas is not showing up, set the fol. property
raise on entry : yes
viewport x and y position to 0
and try runing ,
if the tab canvas is showing up, gradually return to the required position
else check for any hide_view(tab_canvas) code in your form.
or you can reduce the height of content canvas to view tab canvas. Check the window name of content and tab canvas is same.
And in when tab page changed, you write for each tab page name
IF :SYSTEM.TAB_NEW_PAGE='PAGE2' THEN
go_item('some item in tab page 2');
SHOW_VIEW('STACKED_CANVAS');
ELSIF :SYSTEM.TAB_NEW_PAGE='PAGE1'
go_item('some item in tab page 1');
HIDE_VIEW('STACKED_CANVAS');
END IF;
Why that go-item is required?
Suppose your cursor is in an item in the stacked canvas, and if you click on page 1, The stack canvas wont disappear.
