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

Horizontal scrollbar on tab page

Hi,
I'd like to use Designer for a multi-record block on a tab page with a horizontal scrollbar . How should I do this ? It is alright for a vertical scrollbar but what about an horizontal one ? Since I have too many columns to display on one tabbed page.
Thank you,
Denise

If you have many items that they cannot fit into a tab page, I think you have to put them into a Stacked Canvas. This can be done by changing Overflow Style to "Spread table" option in The Module Component containing these items.
Also, you can set WINHSB Module Generator Preference to 'Y' value to add horizontal scrollbar to module Window.
I hope you found solution for your problem.

Scrollbar for Tab canvas

The scrollbar works for tab canvases as well as content canvases. Not sure what you mean by "remains inactive even the layout goes beyond the window".

Regarding Creating Horizontally moving tabbed canvas at runtime

Hi..
Is it possible to create a Horizontal dynamically
moving Tabbed Canvas.
I want to move the particular tab page of the tabbed
canvas horizonatlly during runtime by placing a
horizontal scroll bar.
Could anyone tell me how it in can be done with steps?
Plz reply me asap it is urgent.
Thanks & Regards,
Venkatesan.S

Mmm
Let's see.. there are two tips:
- 1st: modify canvas length dinamically
- 2nd: put the scroll bar to the block into the canvas
Solutions:
- 1st: Use the set_canvas_property built-in (with WITDH parameter)
- 2nd: There are no problems to put an hoprizontal scrollbar associated to the block you're viewing into the page of your tabbed canvas
(To manage the scroll bar.. Have a look at set_block_property built-in)

Scroll bar in tab canvas

hi guys
iam developing a custom form using forms 6i
this is my prob i have a content canvas and a tab canvas in my window i have abt 20 col in my one of tab and i want to use a scroll bar in one tab how can i get it can any one help me urgent
ravi

Well, you are kind of out of luck: no horizontal scrollbar for tab canvases.
Still, here's what I did to solve this problem:
- I make a stacked canvas that would display above the tab-canvas, having an horizontal scrollbar
- on the when-tab-page-changed I write the code needed to get to show/hide the stacked canvas, depending on which tab activates.
It's not so simple, still this works.
If anyone has a better solution without using java beans or some other complications, I'd really like to know how.

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 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.

Regarding creating a Tabbed Canvas that can be viewed horizontally

My current tabbed canvas is too lengthy..so i wanted to reduce teh size and dynamically at runtime i wanted to see the fields by scrolling the horizontal Scrollbar..Is it possible?

let me try to explain clearly..
I am working in Oracle forms 6i..
I have created one form which contains a tabbed canvas with three tabs..
In one particular tab there is a multi record block..the items are placed horizontally.since there are many items placed on the canvas horizontally i cannot able to view all the items at a time.. So is there anyway to sort it out? like by placing a Horizontal scrollbar and try to scroll it so that items are moved horizontally and all the items can be viewed.
I Have done this thing using a stacked Canvas earlier by placing some part of items in content canvas and the remaining moveable items in a stacked canvas and by keeping a Horizontal on the stacked Canvas i could able to view all the items by scrolling the scroll bar,Similar way i wanted to do it on the tabbed Canvas..If anyone has any valuable tips to do that you can reply me..

Venkat

Stacked canvas with horizontal scrollbar

Hi,
In a forms module I want to show a stacked canvas with a horizontal scrollbar. I have set the generator preference POPHSB on every level to yes, but the stacked canvas is still generated without scrollbar. In the Designer help topic "Generated stacked canvas properties" it is stated that the properties horizontal/vertical scrollbar is derived from the object library. But how can I set in Designer the name of an object library object for a stacked canvas? I don't want to override the object CGSO$CANVAS_POPUP because I also have other stacked canvases that doesn't need scrollbars.
Regards,
Vincent Botteman

Hi,
This is what I just have found: you must indeed create a new canvas object in the object library and then enter the name of the new canvas object in the property "Placement Template/Library Obj" of the first Module component on that canvas! Apparently, you can change the canvas by means of the first Module Component on that canvas.

6i, Horizontal Scrollbar on a Tab page

Hi,
I have a big datablock placed on a Tab page. Record layout is Tabular. As the no. of columns are many, they do not fit in the window.
How do I put a horizontal scroll bar to the Tab page so that users can scroll left-right to see hidden/out-of-view columns. (Basically a spreadsheet like functionality with one or more left-most columns fixed and others scrollable).
I went through couple of forum posting suggesting use of stacked canvas and played around with then but still not able to get it work.
An example is highly appreciated.
Thanks

Those columns which are fixed lay on the tab-canvas. Very important: One of this items has to be navigable. Then you create a stacked canvas for the other columns.
e.g.
width of the tabcanvas: 800 pixel. two fixed columns which use 100 pixel each. Then you have 600 pixel for the rest
Let's say 50% of the rest of the columns can be shown at one time. That means, that your stacked canvas is internally 2*600 = width 1200.
The stacked canvas belongs to the content canvas (like the tabcanvas too). Each time you navigate into the tab with the stacked canvas you have to do:
Show_View ('Stacked_Canvas_Name');
and
Hide_View ('Stacked_Canvas_Name');
when you navigate out of the tab.

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?
