I Use Forms [32 Bit] Version 10.1.2.0.2.
Hi All.. I have the same problem with this case ( Place a Tab Canvas within a Tab Canvas ).
but I need help with my case, what if there is more stack canvas, like this :
- I created Tab Canvas first, then
- in my first Tab Canvas I put the new tab canvas (this solved), then

How do put a stack canvas inside the tab canvas

Hi all,
I have content canvas and tab canvas Now i want to put a stack canvas on the tab canvas .suppose tab canvas page are Page1,page2, page3 when i click the page1 then display the stack canvas 1,and when i click page2 then
display stack canvas 3 ..... so on. help me to find the solutions to this Issue
Thanks

You would use the when-tab-page-changed trigger to use hide_view and show_view commands to hide one stacked canvas and show another.
Just keep in mind that for a canvas to be displayed, the cursor must be in an item on that canvas, or at least in an item NOT covered by the canvas.

Tab canvas inside a tab canvas

Anyone knows how to put a tab canvas inside a tab canvas.
thanks.

I did a little test and it works (it'll only take you 3 min)
Create a new Form.
Add 3 Canvases 1 Content and 2 Tab with the following Properties
Content
Vieport X Position on Canvas: 0
Vieport Y Position on Canvas: 0
Width: 540
Height: 324
Master Tabs
Vieport X: 35
Vieport Y: 20
Vieport Width: 460
Vieport Heigth: 280
Detail Tabs
Vieport X: 150
Vieport Y: 95
Vieport Width: 260
Vieport Heigth: 160
Then go to Layout editor and while viewing the Content Canvas go to the menu View -> Stacked View...
From there select both tab canvases to be shown.
Also add a dummy item (i.e a button )somewhere in the form otherwise nothing will appear when you run the form.

Place a Tab Canvas within a Tab Canvas

Oracle Forms 6i.
I have a requirement to put a tab canvas within a tab canvas. However when I try to create a tab canvas within a tab canvas i get a 'FRM-13002: Stacked and Tab canvases must be created within content canvases.'
Does anyone know of a way to achieve this?

Got it working thanks.
For anyone that wants the code:
WHEN-TAB-PAGE-CHANGED - Form Level Trigger
declare
     tb_name varchar2(30);
begin
     tb_name :=get_canvas_property('CANVAS1', topmost_tab_page);
     if tb_name = 'TAB1' then
          show_view('CANVAS1');
          show_view('SUB_CANVAS1');
          go_item('BLOCK1.FIELD1');
     elsif tb_name = 'TAB2' then
          hide_view(''SUB_CANVAS1');
go_item('BLOCK1.FIELD2');
     end if;
end;

Creating tab canvas inside another tab canvas

pleas help me solving the issue...
I want controlling code such that i can create tabpage canvas into another one.
second tab page of first tab canvas it should be visible.
regards
jai

As long as i know something like this is not possible.
But you can emulate it this way (for this example i will assume that you want the smaller tab-canvas placed on the second page of the bigger tab-canvas) :
1. create a tab-canvas
2. create a stacked-canvas with bevel=none
3. create a new tab-canvas and place it on your stacked-canvas
4. make the stacked-canvas invisible
5. through the trigger WHEN-TAB-PAGE-CHANGED make your stacked-canvas visible whenever you are on page 2 and invisible whenever you are on another page.
6. adjust the coordinates of your stacked-canvas so it will appear right above the bigger tab-canvas
Good luck with this

Tab canvas within a tab canvas? Can it be done?

Hello,
I am working in forms 10g. A customer has given me a mock up that contains a tab canvas within a tab on another tab canvas. Is this even possible? If so, can you outline the steps to do so please?
Thanks,
Adam

It is possible, but you cannot create tab-canvas 2 on top of tab canvas 1. Create both tab-canvases on top of the content canvas, the at runtime use SHOW_VIEW and HIDE_VIEW to show or hide the second tab-canvas as needed.

Tabbed canvas on a tabbed canvas

Is it possible within 10g forms to place a tabbed canvas on the tab page of another tabbed canvas? I am not seeing a way to do it, but I if someone else has an idea about this, it would be much appreciated.
Thanks,
c

Thank you for the input. I have a three tabbed main canvas and on the first tab page I have two blocks in a master-detail relationship. The detail block has so many fields displayed that putting another field on it would be difficult without decreasing the size of the other fields or increasing the size of the window and canvas which would in turn effect the other tab pages and all other forms using the same window size. If I were to use the tab canvas on a tab page of the main tabbed canvas would I need to shrink up the main canvas in any way to display the topmost canvas, which represents the detail block, at the bottom of the page? I would still need to display the entire tab page of the main canvas for the sake of the other tab pages or else wouldn't shrinking the main canvas briefly mess up the coordinates of the other fields displayed on the other tab pages?
Also how do I specify that I want the details tabbed canvas to display on the first tab page of the main tabbed canvas? I didn't see in the property palette of the details tabbed canvas an option to tell it to display on a tab page of the main tabbed canvas.
Thanks,

On the First Tab i want to fetch the data from some table say XX_CUSTOM_TABLE.
Now, This should be displayed in Tabular format with Horizontal and vertical scrolling as the table has many columns.
Please give me step by step instructions so that it could be implemented quickly.
P.S : I am using Oracle forms 6i.
Thanks in advance,

Hi,
1. When i open the form only the fields added in the tab canvas are visible.
Where u have drawn the stack canvas,you need to create in the main canvas where ur tab canvas is there and u need to drag it to tab canvas.Have u created the trigger when tab_page_changed?
2. when i change the tab page from tab 1 to tab 2 and then again get back to tab 1, then the stack canvas fields are visible and the fields in tab gets invisible.
Just place the stack canvas correctly after the fields in tab page 1.
3. The stack canvas is not horizontally scrolling.
Just go to the property palette of stack canvas and make yes to both horizontal and vertical to yes.
Do i have to create a stack canvas separately? and then how do i drag it into tab canvas. i am still not getting this. because.
when i open the tab canvas page i do not find the stack layout so that i can drag it like a normal text item.
Yes u need to create a stack canvas separately. Just open the Mani canvas the tab pages are there, then in that click the stack canvas icon and create a stack canvas and create all the fields, and move the stack canvas to the tab page. And u need to create a when tab page changed trigger at form level.

Tab Canvas displaying Stacked Canvas at runtime disappears?

Hi,
I have 3 canvases that contain the following:
1) Content Canvas -- This contains the TREE item.
2) Tab Canvas -- A tab canvas with a single Tab Page
3) Stacked Canvas -- This is a Stack Canvas with a few
text items on it.
4) Single Window.
======At runtime the following actions occur: ==========
1) The Viewport of the stacked canvas is set to the
Viewport of the Tab Page on the Tab Canvas so that it
looks like the Tab Page has a vertical and horizontal
scrollbar with text items displayed.
2) A text item on the Stacked Canvas is in focus as soon
the as the form window is displayed.
===================Problem is : =====================
1) When I select a Node of the Tree Item, the Tab Canvas
automatically disappears(or becomes invisible) , as a
result the stacked canvas displayed within it at
runtime also becomes invisible. I am left with only
the Tree item being displayed.
=======================================================
PS : I have never experienced this problem with just the
content canvas and the Tab Canvas together.
Any soultion to this problem is most appreciated.
Thanks
Sharath

I am experiencing the exact same thing. The width of the tabs in the layout editor is varied depending on the length of the text. However, at run-time, the width of the tabs is fixed, causing the tabs to be wider than the window and a set of VCR buttons to appear in the upper right corner of the canvas. Personally, I think this is a Forms bug. Why would they intentionally let us set the width to variable at design-time only to force a fixed width at run-time?

Tab canvas disappear when the main stacked canvas reach the end of column

Hi all,
I have 3 canvas ( 1 main canvas, 1 stacked canvas ) and this link to 1 tab canvas. All these are in the same window.
Whenever using the keyboard to press enter navigate from column to column and when it reach the end of the main canvas which is about to jump to the stack canvas, the two canvas ( stacked & tab ) was hide by itself. Even I have stated earlier to show all canvas in the pre-block trigger. when I keep on press the enter to jump to the next stacked canvas, this stacked canvas is being shown again. My tab canvas was not appear if I am press the enter key. However, if I press the arrow key down the tab canvas is appear. This I wasn't do any code to call the tab canvas.
When I keep on press enter and reach the end of the stacked canvas again the tab canvas is disappear, unless I have press the arrow key down to display the tab canvas.
Trying to use show_view( tab canvas ) in many trigger but still does not show the effect.
Anyone has this experience before ?
Thanks.

Stacked canvas as a tab element

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

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.

Hello,
When the Layout is open, just add the stacked canvas by selecting it in the tool bar and drawing its bounds onto the tab canvas.
