Tab canvas and Query...

I have a form that only has a tab canvas consisting of 5 different tabs (which contain no inter-relationships). The purpose of the form is to allow queries of the 5 different types of information. This is what is driving me crazy...Each time I select a different tab, I must select a field on the tab before "Entering" a query. If I don't select a field, when I "Enter" a query, it will take be back to the last tab where I queried. I would like for the field to be selected automatically, simply by choosing a new tab. How can I do this?

In WHEN-TAB-PAGE-CHANGED trigger,
put code similar to
IF :SYSTEM.TAB_NEW_PAGE = 'page1' THEN
GO_ITEM ('block1.item1');
ELSIF :SYSTEM.TAB_NEW_PAGE = 'page2 THEN
GO_ITEM ('block2.item1');
etc...
That should do the trick

Tab-Canvas and Stacked-Canvas (Forms 5.0)

Is it possible to design a tab canvas that contains stacked-canvas? I can't create it!

Yes - it is possible to design a tab canvas that contains stacked-canvas. Create a separate canvas with its own block and you can call go_block and the canvas/block will show. You can also call show_view but the canvas you call must be of the type stacked. (aside - a tab canvas seems to automatically act like a stacked canvas). I have used a canvas w/block that sits at the top of the screen by setting it to be only 60 points tall (and it is the first block in the list) then in a when-new-form-instance trigger I call show_view('tab canvas name') and have its viewport begin at 60, therefore the tab canvas fits right under the header canvas. You can then leave this to call other canvases/blocks and return and set up the same situation again. Sometimes I have gotten strange results where no matter what I do it will not show the tab canvas - at this point usually you recreate what won't show and it will then work.
good luck.

Tabbed canvas and co-ordination units

Hi All
I am puzzled with this behaviour
I have a form that has 1 content canvas and 1 tabbed canvas. The form was created with co-ordination using as character. When I run the form. I can see the content and the tabbed canvas.
When I changed the co-ordination units to real/point. The tabbed canvas is not displayed. I tried changing the viewport x and y position and it did not help. When i pressed the next block key, I can see the tabbed canvas displayed at 0,0. What ever value I set in the viewport x/y value, is not helping me.
If i convert the form back to character, it works fine.
Any help is greatly appreciated.

I am using 10g R2. Both my content canvas and tabbed canvas have raise on entry set to No and they are in the same window.
I have the following property for the content canvas
Viewport x 0
Viewport y 0
View width 450
View height 438
raise on entry No
I have the following property for the tab canvas
Viewport x 0
Viewport y 180
View width 450
View height 240
raise on entry No

Tab Canvas and Access Keys

I need to be able to navigate between tabs on a canvas using just keyboard access keys, similar to access keys on buttons.
Can anyone advise on if this is possible and if so how??
Many Thanks,
Jayesh Kavia

I'm want to change my forms resource file to map a key for next tab and previous tab:
eg, for Alt+C to exit a form the entry is:
67 : 8 : "Alt+C" : 32 : "Exit"
Where 32 is the Forms Function Number.
Does anyone know what the forms function numbers for next / previous tab are?
Many Thanks,
Jayesh Kavia

How to change content/stacked canvases to tab canvas

Hi,
I have created a form which has one content canvas and multiple stacked canvases. The content canvas displays the first page and then we hv to click on next to go to the next stacked canvas and so on. I want to try making it in tabs (tab canvas) and then I will decide which one looks better and performs good.
Can you guys please give me a detailed instruction on how to convert my content and stacked canvases to tab canvases. I have never done tab canvas. I tried one, I changed one of my present stacked canvas to tab but all the fields and texts were gone and there were just two tabs in it.
Please suggest. Thanks in advance.

Newbie Help - Tab Canvas with Multiple Pages, Arrow to Navigate between

Hi All,
I am developing my first form. It is a page that requires several pages. I have created a tab canvas and put the pages on (there are 10 pages). When i run the form, i can see the first 4 page headers, and cannot see the other headers. Is there a way to have a arrow at the top so i can click on it to move the display so i can see the other pages?
How would this normally be done? What i am after is a similar multi page navigation to that in the assignment screen, or any oracle screen with several pages.
many thanks
Rupz

Hi, thanks for your reply.
If i press F2, a list of all of the pages appear, but i do not get any arrows.
I have a single tab canvas with 10 pages on it. The pages fit on the canvas, but not on the display window. Do i need to modify the canvas in any way to get the navigation arrows to display?
thanks
Rupz

Add Content Convas to a Form with Tab Canvas

Hi,
I have a From with the tab Canvas (with 3 tabs). I wanted to provide few buttons which are common to all the tabs.
How can i do it?
I know of one way that it can be done is to add the tab canvas to the content canvas and then put the buttons on the Content Canvas. I can't seem to add it(Content Canvas) to the existing form. I tried using a fresh form and then copying the existing tab canvas on to it, it doesn't work.
I don't want to recreate this tab canvas as I have lots of code that has been added to the tab pages.
Is there a way to solve my problem ?
Appreciating in Advance.
Reena

Hi Reena,
Create the content canvas. go to layout editor.
Go to View --> Stacked Views on the menu.
select the tab canvas and say ok.
Now go to Edit --> Select all. Deselect the new content canvas .
Move all these selected items on the tab canvas down so that you can have enough space on the top of content canvas.
Cheers.

Can't change color of Tab Canvas tabs

I'm trying to modify a the background color of a tab canvas, and the color of the canvas itself changes as specified, but I have been unable to change the color of the tabs themselves.
Am I missing something here, or is there a bug, or what?
Thanks for any enlightenment.

Thanks for the info - at least I know to quit looking for something I may have overlooked.
Thanks also for the possible workaround - I may try that.

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

http://photos.ibibo.com/albums/view/415782/8488558/error
What is this error ?
Is there any limit for creating tab canvas in forms 10g ?

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

Form with Tab Canvas

Hi,
I've a form with 12 blocks. We are displaying the these twelve blocks in the tab canvases(Tab attachment Edge: Top). The problem with these tab canvas is user can see only the names of 4 tab canvases. Then he need to navigate using the scrollbar. But the user requirement is that he needs to see all the tabs above in multiple rows. i.e.., In the first row he needs 4 tabs and then in the next line he needs another 4 tabs etc. He do not want to change the Tab attachment Edge to Right/Left. I'm using Forms 6i version. Thanks in advance.

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
