Alv event on keyboard arrow (up or down)

Hello,
i hope that someone can help me with my problem.
i am looking for an event in alv that reacts on the keyboard arrows: cursor up or down.
i know that i can use doubleclick or hotspot event, but my customer wants it by cursor up or down.
i habe a subscreen under the alv-grid, where the details are shown.
and when someone 'walks' through die alv-grid with cursor up or down, the details should be displayed - how can i do this ?
Doubleclick ist second best...
Thanks
Helmut

hi ,
try using Event DELAYED_CHANGED_SEL_CALLBACK. The best example of this event is WE02. When you select one record with a delay of 1 sec you get the details of idoc below. Try and see if meets ur req.

Go to System Preferences->General. There you can set how you wamt thescrool bars to behave.
If you want to see the scrool bars all the time select Always

How do I scroll more than one line at a time in Firefox 4? Scrolling with down-up keyboard arrows is much faster in IE/Chrome.

I have tried using about:config options mousewheel.withnokey.sysnumlines > false and custom set mousewheel.withnokey.numlines, but it makes a difference only when I use a mouse, which I don't use most of the time on this laptop. I use down/up keyboard errors to scroll, and the page scrolls one-line-at-a-time, very slow and lagging. Is there a way around this?
I have reinstalled Chrome as secondary browser only because of this, FF4 otherwise really kicksass. Thank you for an amazing browser and any feedback on my issue.

Well I am using those, but it is not very practical. What puzzles me is that only Firefox has this behaviour, I have tried last versions of IE, Chrome, Opera - all three scroll much faster than Firefox 4 using down/up keyboard arrows.
Thanks for the reply, I really hope to get a solution to this.

Direct selection - moving anchor points with keyboard arrow keys

Hi,
I am using Illustrator CC. I just used the image trace tool to create a vector version of my company logo. It worked pretty well, but I am now just trying to clean it up a bit. I have a few anchor points that I just want to nudge up or down in the smallest increment possible.
I think it would be easier for me to do this using the keyboard arrow keys rather than using the mouse, but the arrow keys cause my selected anchor point to jump by way too large of a distance. I checked to make sure Smart Guides, Snap to Grid, and Snap to Point are all turned off. I can't think of anything else to do.
Can anyone tell me what controls how far the keyboard arrow keys will move an anchor point, and how I can set this to the smallest possible distance?
Thanks in advance,
Paul

Under Preferences (Command-K on Mac), on the first screen there is Keyboard Increment. This is the amount the arrow keys will move selected content, such as anchor points.
I usually keep this at "0.005 in", but when doing things that need extreme accuracy, I change it to "0.0002 in", which on my screen (2560 x 1600) is one pixel at AI's 6400% magnification.

Calendar on iOS 7. Anyone noticed that when you enter text into the "notes section" of a day, the text disappears behind the keyboard rather than scrolling down to keep pace with text entry ? Looks like an 7 glitch to me ?

Doesn't do that for me. Try resetting the phone

How can I log in to my computer? I changed language on keyboard and I shut down my computer.Now keyboard has no numbers, which I need for my pc password

Yesterday I was working on my computer and I changed English to Lithuanian language on the keyboard. I shut down my computer. Now when I want open it, I can't type correct password to access my account . There is left Lithuanian language on keybord, with has no numbers. And I need numbers to use for my password.

It does have numbers of course, they are made by first hitting the ` key (top most left most on a US keyboard) and then the usual number key. Have you tried that? Such combos often don't work in password fields, but you never know.

Such as a computer keyboard.
With BACKSPACE, TAB WITH SETTINGS, DELETE, TYPE OF TYPE, BOLD TYPE, UNDERLINE ETC....
I HAVE A KEYBOARD COVER AND IF I NEED TO USE CERTAIN KEYS I HAVE TO SWITCH TO MY KEYBOARD CASE AND THAT IS VERY INCONVENIENT.
IT IS ALSO A TIME WASTER.
When you installed iOS 8 did you read about the new features? Applications can create custom keyboards…

You need to look for an app that has a custom keyboard with the features you require, I suggest you find one without CAPSLOCK

THANK YOU FOR YOUR TIME
Again you need to look at how to manage the device - these settings can be turned off already & you can edit the 'suggestions' too.
Settings > General > Keyboards > turn Auto-Correction Off.
Sadly you cannot disable autocorrect temporarily, so it's all or nothing.

Table Sorting First Time - show arrow up or down

Hello colleagues,
I successfully sorted table's column without clicking on it using the following code:
usersTableNode.sortElements( GenericNodeElementComparator.asc("userName") );
The code was taken from this thread:
Usage of the Node-Function "sortElements"
<b>I have to show an arrow up or down, without clicking on the column header.</b>I'm dealing with NW04.
Please help me to show this arrow

Hi,
Unfortunately, I'm using NW04 and not NW04s.
Is it possible to show an arrow without clicking on the column's header before?

ALV Event is malfunctioning

Hello gurus,
I created a workbench with an edittable ALV for its data. This ALV has several tabs, lets say 5 tabs with individual event handler declaration. Tabs 1, 2 & 3 shares the same event/class and method declaration. 4&5 shares also the same but different to 1,2, & 3.
I have events handle data change and button click (for a column of buttons that pops up a screen when pressed), which are both standard toolbar. Then I also have event toolbar for my custom icon and event user command to handle these icons.
I run my ALV, tabs 1,2 & 3 have their data first. Then I just copy these data going to tab4.
On tab 4, whenever I click on the standard toolbar 'add row' (+ icon), it adds new row and triggers event handle data change.
Now my problem is, whenever I click on any other icon that triggers alv event, instead of going to their respective event, it always go to the handle data change event. (i.e. when I click on my custom toolbar icon, instead of going to event user command, it triggers the handle data change. Same with when I click on any buttons under the button columns, it triggers handle data change.)
Tab 1,2 & 3 works fine. But 4 & 5 are not. They have the same process and coded with the same logic. The only difference I see is that 4 & 5 has handle data change event while 1,2 & 3 have not.
Please help me analysing what's really causing the issue and what solution to apply to handle this.
Thanks,
Sheera

you need to set the subtotal option only to the dummy field. see the below code related.
"no need of subtot option here..
ls_sort-spos = 1.
ls_sort-fieldname = 'EBELN'.
ls_sort-tabname = 'ITAB'.
ls_sort-up = 'X'.
ls_sort-group = 'UL'.
APPEND ls_sort TO it_sort.
CLEAR ls_sort.
ls_sort-spos = 2.
ls_sort-fieldname = 'D'.
ls_sort-tabname = 'ITAB'.
ls_sort-up = 'X'.
ls_sort-group = 'UL'.
ls_sort-subtot = 'X'. "Only specify here
APPEND ls_sort TO it_sort.

ALV-Event data_changed after searchhelp with userdefined searchhelpexit

Hi there ...
I'm using an OO alv grid with an elementary searchhelp at defined fields.
the search help uses an searchhelpexit, that simply filters data, to show the right stuff
everything works fine!
dependent on the returned value of the searchhelp, I need to trigger a recalculation of values.
the alv-event "data_changed" looks interesting for that issue ... especially the flag "e_onf4_after" ...
BUT: I don't know, when the flag is set :$
the event is raised (with marked flags "e_onf4" and "e_onf4_before") before the Searchhelplist is displayed .... but I need to react AFTER the searchhelp is closed and the selected value is returned ...
all I want to do is:
trigger the recalculation after the user selected a value at the searchhelp
can anybody help me in that case?!
thanks a lot & enjoy your weekend
Markus

Hi,
You can call elementary search help like any popup screen
with function F4IF_FIELD_VALUE_REQUEST.
- Call f4 help manually in the event DATA_CHANGED
- Process your recalculation
- set values on cells..
I hope it helps.

Last point...who archives? On my regular email page I now have the Archive icon to the left of my Delete icon which I would prefer was to the left, first in the line as this is the icon I use mostly. With Folders, my Sent and Trash lists, who needs to archive?
I can help you only with the placement of the icon placement -- if you right-mouse click on the toolbar, then select Customize Toolbar, you can move an icon to where you want it to be.

How keyboard arrows expand rectangular selection?

I have drawn a rectangular selection around an area I want to change contrast and didn't quite size it perfectly to include the photo.
I can try to redraw it, but I would rather use the keyboard arrow keys to increase the size horizontally or vertically, one pixel at a time.
How can I do this using the keyboard arrow keys?
Also in these forums where can I set it to default to subscribe by email for any threads I start or reply to?
Thanks.

Thanks for all the help.
You would think there would be a way to put selection handles on the selection and just drag or keyboard arrow to expand in a give direction.
No shift, control, alt key combination to do this?
Speaking of selection handles, I did something similar by accident once.
I was working with a border in the image and trying to cover up a gummed label that was on the source document which I scanned.
I copy pasted a portion of my image. Somehow I got selection handles on the pasted portion(don't know how). I wanted to move the paste over wihtout destroying what had been underneath before the paste
Anyhow, what happened was I did not move the pasted section but STRETCHED IT. In this case that was OK because I was just stretching the border horizontally and it didn't look bad, but I don't even know what keystroke combination I did to put those selection handles on the paste.

Dreamweaver CC crashes when moving a DIV field with the keyboard arrows.

I'm really fond of the new Dreamweaver CC, but on some occasions, it crashes when moving a DIV field with the keyboard arrows, for example, to move it two or three pixels.
This is happening on a recent pc (i5 / 16Gb ram / Intel SSD / Bootcamped Windows 8 x64)
F12 is also really slow when publishing via Chrome. Firefox or Internet Explorer is faster.
Is there a fix for these issues?
Thanks,
D

Apart from the FluidGrid Layouts feature, DW is not a click and drag app like Photoshop or Muse. You should be using the CSS panels to align elements with floats, margins and padding.
Keep Chrome open and refresh browser (F5).

Keyboard arrows, Home, End keys

In a edit box, such as a search box, my keyboard arrows, Home, End keys do not work since I upgraded to FireFox 8

''my keyboard arrows, Home, End keys do not work...''
That problem is caused by "caret cursor" and the way that Mozilla works with it. Press "F7" reply "No" to turn if off. F7 toggles the setting and you may or may not see the warning but if you do see "No" that would mean you have it on and "No" would turn it off. For a more complete resolution see
* [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#caret Caret Browsing] in<br>http://dmcritchie.mvps.org/firefox/firefox-problems.htm#caret
See how you do with Adobe PDF files after fixing the above. You can have PDF files open by default without Firefox involved except to download them, but I expect you chose to view in your browser. You have a lot more control of reading PDF files outside of Firefox. The plug-in is what allows you to open them in a browser.
