Changing Tab Focus Programmatically

I have a tab canvas with three tabs. I have a stacked canvas for each of the tabs. These stacked canvases display multiple records. When the user switches tabs it displays the correct canvas. Now, lets say I am entering information on tab two and I press down to insert a new record. I have code that returns the cursor to the first item on stacked canvas one, but the tab canvas is still showing focus on the second tab. How can I programmatically reset the focus of the tab canvas to the first tab?

I think the ~right~ way to achieve the tabbed canvas setup is to use a single primary canvas, and a single tabbed canvas with multiple Tab Pages assigned to it. It seems to me if you use this method, the tabs show correctly when the cursor moves to an item on a different tab.
If you press the down-arrow to create a new record, then you might need some special code in the key-down trigger to go_item someplace other than the first field in the block.

Changing tab focus with the keyboard

I've read about changing the tab focus from one page to another programmatically; however, I would like to have shortcut keys to change tabs (like many programs that use CTRL+Tab to change windows within the program).
I could use an event structure to capture keyboard button presses and then change the value of the tab control, but is there a more straightforward approach?
Thanks!

You can set all other controls not to be tabbed through and the tab control to have its pages tabbed through. That way, when you use tab, only the tab control's pages will be on the tabbing list. This, however, is probably less straightforward.
I'm not sure what's the problem with the method you outlined. In most cases, if you want something to happen, you will have to code it. This appeares to be one of those cases. You can make a subVI to do the tabbing for you, if you don't want to have to code all of it in your VI. Pass the reference of the tab control into the VI after you detect the event and use that to decide whether to increase or decrease the tab value. Be sure to cycle the number back to the first page when it reaches the end.

Changing Tab Focus Behavior

I have two machines running Firefox 4.0. Both have Tab Mix Plus installed. Each exhibits a different behavior when opening multiple tabs.
To open multiple tabs, I simply highlight a number of links on a page, right click and select Open Links in New Tabs from the menu
In both cases this action results in each link opening in a new tab. In both cases the focus stays on the current tab.
However on one machine if I change focus by clicking on the tab next to the current one and then close it, the focus goes back to the first tab.
On the other machine if I change focus by clicking on the tab next to the current one and then close it, the focus moves to the tab immediately to the right of the closed tab.. This is the desired behavior.
What do I need to change on the first machine to get it to behave like the second one?
I tried doing a visual compare of the configuration setting on each machine both for Firefox and Tab Mix Plus but couldn't find any difference in settings.

Changing Tab focus while in a User exit. Is this possible?.

We have a user exit that kicks in when saving in a sales screen with different tabs. There seems to be inconsistancy as what tab is focused (chosen/highlighted) afte the user exit completes.
What I wanted to know was whether it was possible to force a certain tabbed screen to be the main focus.
Is that understandable?. I know I have not explained it that well, but hopefully I given enough to put across the problem.
Jas

Hello Jas,
Could you please mention the user exit name that you are using?
Thanks,
Johnson

How do I stop Yahoo mail's popup dialog box from changing the tab focus?

Hi,
When I have a tab opened to Yahoo mail and I open a Yahoo email on my other computer or Blackberry, there's a time delay and at some point, Yahoo shifts my browser focus to display a pop-up dialog box that says "You have been disconnected from chat because you have signed into Yahoo! Messenger from another computer." I can't even switch back to the tab I was on without dismissing the popup.
I'd love it if I could turn off the pop-up, - don't care about the disconnection - but in the meantime, is there some way to prevent Yahoo from changing my tab focus?
Thanks!

Hi Douglass,
You will need to navigate to the following folder.
/Users/yourusername/Library/Mail/V2/MailData
and backup the following file... MessageRules.plist
Open the file in BBedit to confirm your rules are infact inside that particular plist file as Mail will also create backups occasionally.
Once you reinstall, do a compare/replace with the newly created MessageRules.plist and you should be able to bring your "old" rules into your fresh install.
as for mailboxes, those are contained within this folder
/Users/yourusername/Library/Mail/V2/Mailboxes
and it will be up to you to backup those files and File/Import Mailboxes them into the new install.

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.
See:
* [[Troubleshooting extensions and themes]]

Tab to change component focus not "real tab" in jtextarea

Hi,
Assume you have four text field in one panel. The first text field get focus. Then you press tab, the focus will change to next text field... and so on..... If you put one text area in that panel..... the story begins....
When you press tab in text area, it will do "real tab" in that text area....
How do I disable that? I want it so that when you press tab in text area, it will change the focus to next element not do "real tab"...
Thank you.

Feel free to remove parts of the code that you feel
are not required. The code was only posted as a
suggestion. If there are some lines of code that you
don't want then please remove then. You are under no
obligation to use the code as posted. To make the
code shorter you could try shortening the method
names. I used "tabForward" and "tabBackward". You
could use "f" and 'b" to shorten the names.Hehe, nice to have you back.

Please help is it possible in Form Personalization or not if not please suggest the alternative.Forms Personalization is a feature of the Oracle Enterprise Business Suite (EBS) not Oracle Forms. Please post your question in the General EBS Discussion forum. If you have a general Forms question, by all means, ask it here! ;-)

Can you change tabs on a tab control by using boolean buttons?

Need to change tabs by pressing a button instead of using the actual tabs.

Absolutely. First create a local variable for your tab control. Then poll your boolean to tell when its value has changed. Finally write a value to the tab's local variable to change its tab page programmatically.

Is there a way to automatically change tabs with different times set for each tab?

I found a few add-ons that will automatically change tabs based on a configurable time. But all the tabs use the same time setting. What I need is the ability to have tabs displayed for different amounts of time. Ex, Tab 1 for 30 seconds, Tab 2 for 10 seconds, Tab 3 and 4 for 5 seconds. Ideally, I will have the ability to modify these settings as the amount of tabs and the content will change a couple times a week.
Currently I'm using Tab Slideshow with each tab displayed for 15 seconds. But it sounds like Tab Rotate and Auto Toggle Tabs essentially do the same. If there is already a solution that would be great but if not is there someone available for hire to help modify one of the existing add-ons? Thank you in advance for your time.

Currently Firefox don't have any options like that.
You can ask the Addon developers

Programatically change control focus to generate and Event......

I'm adding some user enhancement (anti-screw-it-up functions) to insure the desired process is executed.
Primary question: If I have an event that is handles by a value change in a text control, (event happens when you hit Enter or exit control with mouse) will the event also occur if you exit the control by programatically changing the focus to another control ?
I'm going to try and set up a temp vi to test this but wanted to see if anyone had tried this and if it works or not. My other option is to set up multiple event cases but I was hoping to use a single case to handle everything.
A few details, I have a test system that tests a product automatically when the product is placed in a cradle and the cradle is moved into position and activates a prox sensor. At end of test, system waits for prox sensor to de-activate before resetting the system.
If a unit fails, there are rework options and the unit can be retested. When it fails, a label prints defining the failure modes and provides a failing serial number. When the unit is retested, the failing serial number is entered into a text control. I want the re-test sequence (queued up in the Event) to occur when either 1, a failing serial number is entered or two a button is pressed (with mouse) I'm pretty sure pressing a button would in turn automatically create the text control change event so my button can probably be a dummy button just for appearances.
Where the hole is if the user enters a failed serial # and doesn't exit the control and then engages a pump to start the test. I can use a 'Empty Path/String' function but the control will continue to show empty as if nothing was entered until the Enter key is pressed or the mouse is used to exit the control.
If I can generate the event by changing the focus, then it will insure that if a failing s/n is entered, the re-test sequence occurs and if nothing exists in that field, it performs a first time test.
A little long winded for sure but any thoughts are appreciated.
Can't really post any simple code as this feature is in my top level vi and I have a really big app that doesn't warrant uploading.

Solved!
Go to Solution.

Actually, changing the focus alone did not trigger the event but I was able to then utilize the Empty Path/String function to drive a Value(Signaling) node for the control.

Help in Changing Initial Focus in Jpanel?

HI
I have extended JPanel to create a class which has many components like JButtons etc. This class is reusable and has to be used at many places.
When I include this class in a JFrame, the focus is always with the first component of my class. But I want the initial Focus to be with another component.
I can do this by calling some method from outside my class but I do not want the user to bother with this extra function calling. Is there any way to change initial focus from within my class? I have already tried grabFocus() and requestFocus() but these methods have no effect before frame packing. Can anybody suggest some workaround?
Regards
Abhinit Kumar

You have to do it after the frame is visible. Assuming you class is not a singleton, make the call to requestFocus the last thing in the contructor.

Want to change image properties programmatically

want to change image properties programmatically like
adjust_to_fit,selection_rectangle,pane,show_pallete.
Reply as soon as possible.
[email protected]

I understand.
In terms of for the initial Ecommerce switchover we mass updated the MMIMAGE field in partsmaster so that the assumed naming convention of the image files are ITEMCODE.jpg.
Your solution is good which covers the instance where the image file field is empty and then putting in a empty image field in there.
The other scenario is that the MMIMAGE field is filled put the physical .jpg file is missing in the file system. Is there a way to handle that.
I checked already the netpoint thumbnail handler .dll and browsed over the available member properties / methods but I don't think such a config exists.
