Controlling navigation, preventing tab and scroll

I have a form (page size formatted for the screen) with Previous and Next buttons. And I have code attached to the Next button that prevents the user from going to the next page until all required fields have been entered.
However the user can still tab or scroll to the next page, bypassing the code. Is it possible to control the tabbing order so that when the last item on the page is reached, it tabs back to the first item on that same page (rather than jumping to the first item on the next page as it does now)?
And is it possible to turn off the scroll bar?

The only way I can think of would be to make all the successive pages invisible and make the next page visible only if the script on your Next button passes validation. If the validation fails, you can reset the focus to the first fillable field on the current page. I don't know of any way to disable the scroll bar for the form.

Controlling navigation between tabs.

Hi all,
I have 5 tabs in a sequence in a tab strip control. The first tab is the main tab. The user has to enter data into this tab before he can proceed to anyother tab. My problem is that I have to navigate to a specific tab based on the data he enters on the main tab i.e. when the user selects a specific check box and presses the enter key, the system will navigate to that tab for data entry. Any help on how i can do this will be appreciated.
regards,
Hamza

Store the tab name into tab control activetab field like mytabstrip-activetab = 'yourtabname'.if not working, use function code of tab.

Keyboard Navigation with Tab Control

We have a tab control in a form and it has several pages.
On one of the tabs we show data from a multi row block, the first 3 columns are on the tab canvas, then we have a stacked canvas that scrolls left/right that shows the rest of the data. We fix the first three columns as they give context to the rest of the rwo that is scrolled within the tacked region.
Now the problem:
When focus is on one of the columns displayed on the tab page we can press CTRL-TAB and the tab switches to the next tab page.
If focus is on one of the fields on the stacked canvas CTRL-TAB doesn't navigate to the next tab page - it attempts to switch windows.
It looks like the items that aren't onthe tab canvas, but are on the stacked canvas, aren't party to the CTRL-TAB event?
Has anyone else experienved this problem? Or know of a work around?
Regards,
Bren

When I use CTRL-TAB just the trigger key-next-item fires. In our environment we use CTRL-PageUp/Down to switch the tab canvas. But I think the event that is really fired is key-nxtblk. So on forms-level I added the triggers key-nxtblk/prvblk that call my procedure next-/previous-tab-page.
In the when-new-forms-instance trigger I initiate a plsql-table, that has the following record type as a rowtype:
TYPE TabPage_Rec IS RECORD
(TabPage Varchar2(80),
First_item Varchar2(80));
So each tab page 'knows' its predecessor and successor. I then implemented two procedures next_tab_page and previous_tab_page, that iterate the plsql-table and set the canvas_property TOPMOST_TAB_PAGE to the requested value and navigate to the first item on the tab page.
That way you are mostly independent of the way your form is designed (blocks, items, order in object navigator). It is a bit of an investment and you have to keep it consistent to the way your form changes tabwise, but I found it quite handy.
Hope this helps.

Bettina

When I play a youtube video in one tab, then scroll up and down in any tab, the audio from the youtube video gets choppy and cuts out for a second. How to fix?

I just want to be able to go on other websites and scroll while playing music (smoothly) on youtube in another tab.
I don't think this happened until after I updated my firefox to 13 and my shockwave flash plug-in to 11.3.300.257
How can I fix this cutting out and choppy-ness in youtube videos when I scroll?
Thanks so much!

Try to disable hardware acceleration.

When I open another Tab and type in a website address, after the site loads the URL in the navigation bar disappears. Why?

When I open a new tab and type in the website url, after the website loads the website url disappears. In order for me to get it to come back, I have to right click on the navigation bar and click undo. why is this?

Did this happen immediately after the reset or at a later time?
Does this only happen on a new tab?
What is the current setting for the new tab page as set via the browser.newtab.url pref?
You can open the <b>about:config</b> page via the location bar.

"Tab" control and Tab order of controls inside the tab

Hello everybody,
I have created the tab control with 6 'tabs', inside every tab I have some controls, like edit fields etc. I wanted to make an order of controls for every tab, so I have selected the option "Tab-order settings" from menu "Edit" (sorry for translation, I use non-English version of LabView), and tried to set the order. After saving it with "OK" button it turned out that the order is not changed. Simple it seems that the option doesn't work for controls in tabs. Is this a bug or do you have a solution for this?
TIA,
Yazilim.

Sorry LabviewGuru, but I haven't found anything concerning Tab control and tab order inside it. Of course, I have found the topic "tabbing through front panel objects", but it simply describes how to change order for standard controls, not for controls which are inside the Tab control. But maybe you have another, extended help? So can you please copy and paste to discussion forum message this part of your help which concerns the Tab control and tab order, and then send the message?
TIA,
Yazilim.

Tabbed navigation,Theme change and User define templates problem

Hi,
·     I have created an application in which I have defined many page,page regions,buttons,forms templates myself.
·     The end user has now requested for a tabbed look and feel for the same and that too in a different theme (color red)
·     However, inclusion of tabs to the application plus a change in the theme color (to red) in this case causes all user defined templates to behave erratically.
·     I guess these templates will have to be redefined in this new theme. I tried to copy some of these today but got weird results.
Without all these templates in place the look and feel of the application will not be as usual.
·     Also,I had posted a thread on the APEX forums concerning tabs and have received information that each page in the application has to be manually added to the tab set in a situation such as this.This will really increase the time taken to achieve the desired application navigation.
I would appreciate some good advice as how to get this appliction navigation running smoothly in a tabbed format in the least possible time.
Thanks and Regards,
Priya Jetley

Hello,
I would have a look at the Lists in Shared Components which allow you to create Tabs as well.
They are a bit more flexible.

How do I prevent tab focus from changing when I scroll tabs with the mouse wheel? [SOLVED]

Whenever I scroll my tabs with the mouse scroll wheel the tab focus changes from the page I'm currently on to the tab being scrolled to. I usually have a large list of tabs open and I depend on being able to scroll tabs without changing page focus to keep myself organized.
Also, I'd like to disable tab scroll wrapping; Once I've scrolled my tabs to the end I'd like it to stop scrolling, not wrap around to the start of my tabs.
Is there a way to disable these features and revert to the tab scrolling behaviour of a previous version of Firefox?

This is not a standard feature and can be caused by an extension.
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Navigation of iPhoto and iTunes not possible by Remote Control

Navigation of iPhoto and iTunes not possible by Remote Control after upgrading from Leo to Mountain Lion. I miss this functionality because it was nice to see may photoes directly on the iMac-Screen as well to hear the Music on my Radio. No chance to implement this function again by a newer upgrade?

Answer to captfred and mende1:
I am using already AppleTV, but only for streaming into a different room on to my TV - it is great!
But I like to hear all my iTunes Music by LineOut Cable from iMac to my Stereo Device.
I can activate music titles in iTunes by Apple Remote, but only for jumping from Title to Title and not back to Albums or Playlists etc.

Tab and control buttons do not work in Firefox (they work in other browsers) AND I switched to a new keyboard.

The tab and control buttons are not working the Firefox browser (My browser is up-to-date). The buttons work in IE and Chrome, however, before I realized that, I even switched out my keyboard to a brand new one hoping it would solve the issue.

Thank you--there were a few random extensions I had not added (spyware, maybe?). Once I removed those the issue was fixed!
