Tab Canvas ScrollBar

I using WIN98 and Forms 6i, when I run my forms the scroll bar is disabled on the 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".

  • 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

  • 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.

  • 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

    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?

  • 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

  • Setting stacked canvas properties when inside a tab canvas

    Hi all,
    I grope setting the x and y position of a stacked canvas programmatically : I work inside a tab canvas , there is one multirecord based block which is split into two tab pages. The problem is that the x and y positions of each first item in each tab of the block are no the same. And I want to hide and show the stacked canvas on which is based the scrollbar of the block , according to the top_most_tab_page.
    The stacked canvas has the same width and height as the tab canvas ; it has viewport width set to the width of the scrollbar , say 0.415 ; it has viewport height set to the length of the scrollbar , say 1.833 ; the viewport X/Y position on canvas properties are set to 0.
    I tried to set the VIEWPORT_X_POS and VIEWPORT_Y_POS properties of the view programmatically to place the scrollbar just sticky with the first item when in each tab page , but the scrollbar is not displayed on the desired place. It is moved.
    So how to place the stacked canvas at the right position to be stuck with the left first item ?
    Thank you very much indeed.

    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.

  • 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.
