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.

  • Scrollbar for Tab canvas

    Hi
    I have added a scrollbar on window for Tab canvas but remains inactive even the layout goes beyond the window.But it works for Content 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".

  • 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.

  • 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.)

  • 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..

  • 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.

  • 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)

  • 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.

    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.

  • 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.

  • 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

  • How to embed an applet on a tab canvas of a form

    Hi, I am using JDeveloper 10.1.2.3 and 10 g DB. I have a requirement where I have to allow users to digitally sign or authorize an application in oracle forms. We use Topaz systems to sign all our documents in java. Now users want this facility in their oracle forms applications as well. I have written a bean that allows users to sign. I called this java bean from forms on click of a button and an applet pops up where in user sign and on clicking save button the signature is sent back to the form. However, what i was hoping for was to have this applet embedded within a tabbed canvas of the form, so that it appears that the user is signing on the form. This will also be useful when I have to load the signature back to the form. I don't think a separate hanging applet will look good.
    Can anyone help me please.

    as you already have a bean, try to show the frame of the java-applet inside the bean-area. Maybe there is also a class in your java-program yo can call directly without having to work with the apllet itself. it would also be helpful if you could post the code for your java-bean.

  • 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.
