TAB CANVAS Question

Hiiii
i want to ask if i can detrmine the number of Tabs to be shown at the tab page at the same Time and the the others to be in the List that appear with the Tabs when the TabPage is full ....

I don't understand your question. When you are designing your form, you know the number of tabs that can be shown at the same time when you test the form. If you have too many tabs, then you can show some tabs and hide the others. You can use a tab or a button to show and hide a set of tabs.

Tabbed canvas question...

I have a tabbed canvas with 2 tab pages on it which is set on a master canvas. On the master canvas I have some items.
How do i make it so when I click on an item not in the tabbed canvas that the tab shown on the tabbed canvas is the first one???

i donno if i could actually understand your question correctly, but by what i cud make out, you want to progamatically goto the first tab page of the tab canvas by pressing a button in the main canvas,
to do that u can write go_item(any_item_on_that_page), in the when button pressed trigger of the button in the main canvas.
this will take you to the tab page, also set "raise on entry" property to TRUE of the tab canvas.
i hope it works for u

How to put a long tab canvas on 2 or more lignes

I have 15 basic tables ( 2 or 3 fields).
I would like to manage tese tables from one page.
When I generated the page I got a long tab canvas that I should scroll at rigth to see the rest of the tabs;
My question is : can I put these tabs under 2 or more lines
Thanks in advance

Monta,
This is more a UIX question - well, I assume you are using UIX - than a JHeadstart question. It is not something you solve in a pre-generation way.
The easiest way to address this might be to edit the generated <app>TabBar.uit file. It includes a single tabBar element that stretches along the full length of the page. What you can do is include a second or even more tabBar elements, each having a subset of your tabs. Include the tabBar elements in a flow layout: as long as they fit on the page, they will be displayed a single line, when that does not fit anymore it starts to wrap.
<flowLayout>
<contents>
<tabBar selectedIndex="${uix.rootAttr.selectedIndex}">
<contents>
<link text="Departments1" destination="javascript:doNavigate('StartDepartments1.do');"/>
<link text="Employees1" destination="javascript:doNavigate('StartEmployees1.do');"/>
</contents>
<attributeMap>
<rootAttributeMap/>
</attributeMap>
<childMap>
<rootChildMap/>
</childMap>
</tabBar>
<tabBar selectedIndex="${uix.rootAttr.selectedIndex}">
<contents>
<link text="Extra Tab" destination="javascript:doNavigate('StartDepartments1.do');" />
<link text="Nog een tab" destination="javascript:doNavigate('StartEmployees1.do');"/>
<link text="Salesteam" destination="javascript:doNavigate('StartSalesteam.do');"/>
</contents>
<attributeMap>
<rootAttributeMap/>
</attributeMap>
<childMap>
<rootChildMap/>
</childMap>
</tabBar>
</contents>
</flowLayout>
However, there is an issue with setting the correct selected index on the tabbars. You will probably have to write some JavaScript to get that exactly right; right now, selecting the first tab in any of the tabBar elements will highlight the first tab in all tabbars...

Tab Canvas with Child Block

I have a question about a tab canvas. I have a parent child relationship where I would like to have the child records each placed on a differnt tab of a tab canvas. At most there will be 7 child records so at most there would be 7 tabs. My question is, is there a way to display the child records on the tabs where each row in the child block in on different tabs. The only way I can think of doing this is by having 7 child blocks each referring to a differnt child record. Is there a cleaner way of doing this with just one child block?
Thanks
Diane

You can do it if you are willing to write all of the code to manage it. Not recommended.
The alternative is to have a seperate block on each tab, each one a detail of the one master. Each of the seven would have the criteria to only show the appropriate data.

FRM-40202 and mandatory items on a multi-tab canvas

Hi all !
Short technical question for you guys : let's say that I have datablock whose fields are displayed on different tabs of a same tab canvas. Now, let's say that two fields of this datablock are defined as mandatory : one on the first tab, the other on the last.
My problem is that my form doesn't behave correctly :
Good behavior -> After creating a record on the first tab without filling the mandatory record of the last tab, if I try to create a new record => I get a FRM-40202 error, and Forms forces me to fill the mandatory field of the last tab. Nice.
Bad behavior -> After creating a record on the first tab, I try to go to the last tab by clicking the appropriate tag name in order to fill the mandadory field => I get a FRM-40202, and Forms leaves me on the first tab, unable to fill in my record properly. I thought that as long as I wasn't leaving my record, I wasn't supposed to get a FRM-40202 error...
How would you deal with this kind of error ? How can I get this kind of error while not leaving the record ?
Thanks for your ideas and your help
Regards,

Hi,
are you sure you're not navigating to another record or block? (or trying to save...) Make sure it enabling debugging messages or tracing it...
The error message in thiscase is clear...

When New Tab Canvas/Page?

What is the best way to determine when you user has navigated to a new tab canvas/page when the navigation does not occur by clicking on the tab canvas's Tab? For instance, when the user clicks a button item that navigates to a different tab canvas/page I want to disable the tab canvas/page the user came from.
Any help would be greatly appreciated.

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

How to change the background color of a Tab Canvas

Hi All,
I accidentally changed existing background color of a tab Canvas to ' gray' which is not matching with main canvas (which has default).
How can I change background color to default. Please help me.
-Thanks

In the property palette of the tab page, click on the "Background Color" property and click the "Inherit" button on the top of the property palette, this will revert the value of the property to the default when the tab page was created which is <Unspecified>.
But if your tab page has inherited the color from a property class it will revert to what was specified in the property class.

Tab Canvas

Hi,
I am using Forms 10g. I have Content canvas named CANVAS1 display few items from BLK1. I created a tab canvas called TAB_CAN contains TAB_PAGE1 and TAB_PAGE2, display items from BLK2
I would like to show the form in enter query mode and Form should display both CANVAS1 and TAB_CAN
Content canvas only displayed if i write in when-new-form-instance
show_view('canvas1');
show_view('tab_can');
go_item('blk2.item1);
go_item('blk1.item1)
enter-query;
tab canvas only displayed if i write code like this in write in when-new-form-instance
show_view('canvas1');
show_view('tab_can');
go_item('blk1.item1)
go_item('blk2.item1);
enter-query;
So, I request you to write a code to display both canvases and control should be in contant canvas and form should be enter-query mode.
Regards,
Murali

Hello Murali,
As you are saying you want to show a Content canvas (Canvas1) and Tab Canvas (Tab_Can) both at the same time, you need to use more than one window for this.
Actually at any instant of time, you can show only one canvas on any window. So have two windows WINDOW 1 and WINDOW 2.
In Content canvas, set the window as WINDOW1, and in WINDOW1 set the primary canvas as CANVAS1. And, for tab canvas actually you should have another content canvas(CANVAS2) on which you have placed this Tab_Can. So in content canvas (CANVAS2), set the window as WINDOW2, and in WINDOW2 set the primary canvas as CANVAS2.
It will work i feel.

Tab canvas color

Hi,
I had a form with content/stacked canvases and I converted all of them to tab so that it would be much easier for the users to view. Everything's working fine but somehow the color of all the canvases has changed to light gray. Earlier my canvases were teal (which is by default in 10g). I want to keep the default color i.e. teal, how can I do that?
Thanks in advance.

You can set all or some of the tab canvas's pages the background color you wish:
Open the object navigator , and all the tab pages of the tab canvas.
Right - click on each one - or press F4 - to activate the property palette. Change the background color as you like....
Note: you can do this in just one click..... You simply select the tab pages and preesing F4 you alter the background color.....
Greetings.

Tab canvas on a content Canvas

Hi,
I need to put a tab canvas on a content canvas in 10g R2.
and have items from the same data block distributed across the canvases.
I have set them up with the appropriate viewport for the tab canvas, but at runtime, the tab canvas does not appear untill an item on it gets the focus.
Both canvases are set to the same window.
I'm sure this is possible and I think I have done it before but for some unknown reason can't seem to remember how !.
Thanks in Advance
Regards,
Tony Garabedian

Hi Steve,
Yup, it is definitely related to the window, if the window is the form's console window and the window is the first window created in the form (default window created with the first canvas mostly WINDOW1) the tab canvas is behaving in that way.
Create a new window and make sure that this window is not the console window and the behavior is very much normal, the tab canvas appears as soon as the window gets focused.
This what I have found out for now, if later testing shows anything else I'll post the results.
Regards,
Tony Garabedian
I just added a stack canvas on that same window and the problem returned....
So I rearranged the canvases, and purposely set the canvas on the console window, it worked, so now it seems that the problem appears if you have a stacked canvas AND a tab canvas on the same window.
Hope this ain't a bug it sure looks and acts like one though.

Tab Canvas on a STACKED Canvas?

Is it possible to have a tab canvas ON (IN) a stacked canvas? Or can a tab canvas ONLY be placed on a content canvas?
Thanks!

Hi,
Can you tell the requirement clearly, whether you need to create a tab canvas on stacked canvas, a tab canvas in stacked canvas.
1.Stack Canvas in Tab canvas
First you need to create a tab canvas in the content canvas then you need to create a stack canvas on the content canvas, then you need to align it properly.
