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.

Horizontal ScrollBar disables for Tab Canvas

Dear OTN Members,
I am developing a form with tab canvases.
If I set Horizontal Scroll Bar property to true, it comes as
disabled during the execution of the form. I am only able to
move to the rest of the items through keyboard.
Thanks in Advance.
Bye

Hi,
not directly. However, if - at runtime - you overlay parts of the tab canvas with a stacked canvas, then you could have this showing a horizontal scroll bar. All you tab canvas content need to be on the stack canvas though.

The Tab Canvas

In my application I have two canvases on the one window. Each of the canvas has multiple pages. At some point I need to make all pages of one of the canvas not visible. I use SET_TAB_PAGE_PROPERTY(tab_page_id,visible, property_false), but I'm getting 'FRM-41387 Cannot set VISIBLE attribute of last enterable page'. When I have one page visible on the canvas (first or last doesn't matter) it works fine. Is it possible to make all pages not visible?

Thanks for the tip, Hide_View along with Show_View have been a combination that solved my problem.

Forms 5 Tab Canvas & Horizontal Scrollbar

We are trying to implement a tab canvas which will hold a multi-record data block. The difficulty is that we would like to display a lot of fields and there is no Horizontal Scrollbar easily available for the Tab Canvas.
We are thinking about "simulating" a tab canvas by using stacked canvases. The stacked canvas allows us to have the scrollbar, but looses some of the look & feel of a tab canvas.
Anyone try to do this in Forms 5? How about anyone try to place a stacked canvas on top of a tab canvas?

We're using forms 6.0.8.8. Our standard practice is to never put items on a tab canvas, instead we put stacked canvas' on the tab canvas. Besides having canvas scroll bars, it also provides a basis to work around documented bugs for refreshing/resizing windows when returning from other forms/windows of different sizes etc.

Horizontal Scrollbar on Tab Canvas

Hello,
I have to show horizontal scrollbar on my tab canvas.
I have one Content canvas on this i hv 4 tab canvas with different datablocks. Need to show horizontal scrollbar as the number of fields are the more than tab canvas size.
Please assist.
Is there any other workaround, if it is not possible through any property??
Thank you in advance.

1) create a stack canvas and assign window to it
2) create your items on stack canvas
3) set the stack canvas view port width and height according to your visible area of TAB canvas (the size of canvas must be more than View port)
4) set its X and Y position according to the TABs
5) set show scroll bar to YES horizontally
6) set WHEN-TAB-PAGE-CHANGED trigger to show and hide canvases based on current tab selection.
Hope you got the idea

Runtime tab canvas does not look the same as designed in layout editor.

I created a tab canvas with the following physical properties:
Corner Style - Chamfered
Width Style - Variable
Active Style - Bold
The canvas looks nice in the layout editor, with the above properties. However, at runtime, the tab canvas seems to ignore the above properties and instead shows up with non-chamfered looking (whatever chamfered means) fixed-width rectangular tabs and the active tab page label is not in bold font. Is there a runtime setting that I'm missing here?
null

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?

Oracle Forms 10G(tabbed canvasses not working the same as in Forms 6i)

Hi everyone,
I have a form which gets called from another form through a list of value. The called form(second form) has a group of tabbed canvases which get displayed depending on the parameters passed from the first form.
The Form is working prefectly fine in Forms 6i but when I converted the same form in to forms 10G it does not seem to work the same way. The tabbed canvasses are not getting displayed. I am manually having to press the execute query to get data displayed in the tabbed canvasses. I checked the parameters that are being passed and they are the same as that in Forms 6i.
Please let me know where my 10G Form is going wrong. Appreciate your help, please send me an email on [email protected]
Thanks

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.

Tab canvas on the main window

I have placed some items of the block on the tab canvas but ID is on the content canvas. When the query is executed. the tab canvas only appears when the navigation is transfered to the first item in the tab canvas. I want that at runtime. The tab canvas should appear irrespective of the navigation.. Could somebody help me with that

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Bogdan Dincescu ([email protected]):

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

Forms 6i, Stacked & Tabbed Canvas- Wierd behaviour

Hi,
I am having a wierd problem:
Scenario:
I have a datablock of 40 columns.
I put 1 (say col-1 on page_1 and col-21 on page_2) column each on two different TAB pages.
I created 2 stacked canvases: page_1_stacked & page_2_stacked
I put col-2 to col-10 on page_1_stacked
and col-22 to col-40 on page_2_stacked
I used the following code to show/hide the appropriate cols/stack canvases when the users changes Tab pages:
[when-tab-page-changed
if (:system.tab_new_page ='PAGE_1')
     then
     show_view('PAGE_1_STACKED');
     hide_view(''PAGE_2_STACKED'');
elsif (:system.tab_new_page ='PAGE_2')
     then
     hide_view('PAGE_1_STACKED');
     show_view(''PAGE_2_STACKED'');
end if;
Problem:
Everything seems to work fine, the stacked canvases show/hide as expected, but --->as soon as I put my cursor in any column on TABBED PAGE (here col-1 or col-21), all the stacked canvases vanish
-->if as a result of above case where I put the cursor in a tabbed-page col and canvas vanished, I navigate to the next field (which is on canvas), the canvas shows up (which is normal)....but then this canvas wont get hidden with my hide view... and end up with all stacked canvases shown together or none at all
I have played around with all the properties and am really trapped.
Please help!
Thanks.

Devang, are you aware that if you put the cursor focus in a field, Forms will ignore any show_view or hide_view commands if they cause the cursor to disappear? And if your cursor focus is in a field in a stacked view, hide_view will not work. Forms will not let you hide or cover up what ever item is identified by :System.Cursor_Item.
I do not know why you need Col_1 or col_21 on the tab canvas. Put them on your stacked canvasses, too.
Use a when-new-item-instance block-level trigger to determine which tab page should be displayed. If :System.trigger_item = col_1 through col_20, make sure Page_1 is displayed, and for col_21 through col_40, make sure Page_2 is displayed.
Similarly, use a when-tab-page-changed trigger to move the cursor to the correct canvas. You wouldn't even need to use show_view or hide_view, Forms will do that for you each time you move into an item on either canvas.
And why are you using two canvases anyway? Since you are using a horizontal scrollbar, why not put them all on a single canvas? (And then you wouldn't need the tab pages.)

FRM-13002 : Stacked and Tab Canvas must be created within Content Canvas

Hi,
I have a Tab Canvas with 2 pages on it.
In one of the pages the data to be displayed will be
out of the region(size or length) of that page.
I read in this forum for the same problem, the
member had suggested to use a Stacked Canvas on that
Tab page alone and enable the scrollbars of the stacked canvas.
When I drag and drop a stacked canvas on a tab page
of the tab canvas I get the following error:
FRM-13002 : Stacked and Tab Canvas must be created
within content canvas.
Any help is appreciated.
Thanks in advance

Hi,
I am breaking my head over this.
I am still unable to solve this issue.
========The Requirement is as follows :===========
When I select a Tab Page of a Tab canvas, I get a
combo box with items in it. When I select an item from
the combo box, based on the item selected, I am
retrieveing the data from the database and displaying
it in that Tab Page itself. This data is in a matrix
format. i,e Has a number of rows and columns.
Without a Horizontal and a Vertical Toolbar attached
to the Tab Page I would be unable to view all the records
that are displayed on that Tab Page.
Any suggestions or examples is most welcome and
appreciated.
NOTE : ALso in what situations can we use a stacked
canvas, if the designer does not allow me to
use it with other canvases?.
Thanks in advance
Sharath.
