When-mouse-enter forms 10g

Hi, everybody.
I have a problem with forms 10g (web) in any sub-version. The problem is that the events when-mouse (enter, leave, ...) does not seem to get fired.
Is there anything I can do to solve the problem (a parameter to be set, anything to do in the form).
Any help will be appreciated,
Thank you.

-> Why it is still documented? Will we get back a client server forms?
I wish! But I am sure it is hopeless. They probably need to leave the when-mouse-enter documentation for backward compatibility -- old forms compiled and running in the Web Forms environment. The traffic would be horrendous. I have WME and WML triggers running, and on some forms, rolling the mouse across the canvas causes a lot of flickering -- item prompts flicker. And then there is the mouse-x,y-pos and when-mouse-move. Those are supported in 6i Client/Server, too. I used it to create a drag and drop functionality. Man, does THAT cause some massive trigger firing!!! Trust me, it would NOT work in a web environment.
And yes, "Hai" is apparently something like an abbreviation for Hello -- a little more formal and polite than Hi. Its use still puzzles me, but apparently that is the reasoning of those who use it. ?:|

When-mouse-enter in 10g

I have got Forms 10g installed and tried to use WHEN-MOUSE-ENTER, it didn't work. I looked up the online help and got a breakdown on usage. Couldn't see what i was doing wrong, googled found out WME does not work in 9i. My question does it work in 10g and if it doesn't why the hell don't oracle update their Online help docs which are installed with the product.

That's all well and good, Suresh. Now please look up the on-line documentation in the latest release of Forms Builder 10g.
You will find the following. Nowhere does it warn NOT to use the trigger! (Jan, are you reading this?)
When-Mouse-Enter Trigger 
Description 
Fires when the mouse enters an item or canvas if one of the following events occurs: 
* if attached to the form, when the mouse enters any canvas or item in the form 
* if attached to a block, when the mouse enters any item in the block 
* if attached to an item, when the mouse enters the item

Tooltips and When-Mouse-Enter trigger

Are there any plans in Dev6 or beyond to allow a dynamic change
to the item property TOOLTIP_TEXT from the item's When-Mouse-
Enter trigger or a program unit called from this trigger? Let's
say the tooltip text value changes when the value of the item
changes. Trying to handle this scenario thru other triggers is
rather inefficient and can be time-consuming to make sure all
cases are handled. Is this going to be addressed at some point,
or should we just hang our heads and say "Oh well, that would
have been nice..."

Steve - Why are you bothering to code tooltips when automatic ones are available as item properties ?These forms were first created in Forms 4.5 -- I don't think tooltips existed there. But tooltips still wouldn't work -- in a multirecord block with the code values being unique for several different records, we want the unique description for each unique value.
And when there are several dozen values all over the screen, it would be necessary to lookup and store the description for every value, even though the users would seldom access them. So lookup ONLY on demand is more efficient.
It is a standard process with everything possible stored in a PLL, so the WME lookup works great. And tailoring it for the web with when-mouse-click was not tough to add on.

When mouse Entered, get block/name.

I need to create some java code that, on, when-mouse-entered, and when-mouse-exited, the java code will pass the item's block name and item name back to the form.
Ideally I would like to create generic code to use with any item. i.e. I don't want to 'hard-code' block and item name's into the java code.
Example:
-in forms, create a text item (:BLOCK1.ITEM12)
-set item's implementation class to RecognizeMouseEnteredExited
-When mouse entered/exited, pass items block/name of item to Oracle forms.
Assumptions:
I am assuming I need to tap into Oracle Forms IView interface to extract the item id and name, but as much assistance with the actual code would be GREAT!
Thanks

You can get it with :system.record_number. To determine the position in the multi-record block use get_block_property('block', top_record)

Loading http://abc:8889/forms/java/printtext.jar from JAR cache
This tells me you are using a 3rd party or locally developed Java Bean to perform some type of print function. Is this correct?
java.lang.ClassNotFoundException: java.io.IOException: open HTTP connection failed.Does your printtext.jar Java Bean need to open an HTTP connection in order to print?
Have you been able to print in the past using this Java Bean? Where did you get the Java Bean?
RegisterWebUtil - Loading WebUtil Version 10.1.2.0Your form appears to be using WebUtil. Has it been successfully configured?
Honestly, you need to list the following minimum information when you post a question; it gives us all or most of the information we need to help you and it eliminates the need for us to ask for this information. Please always include:

Error when debugging oracle forms 10g

What plugin do you use? JAva-Plugin or jinitiator?

JInternalFrame, auto activate when mouse enters the frame

Hi, is there a simple way to make the JInternalFrames automatically get activated as soon as the mouse enters them?
I would like this in general, but specifically I need it for a drag'n drop operation. I want to drag an item from a JTable in one frame to another JTable in another frame. This works perfectly, even if the recepient frame is not active, what doesn't work is to scroll the recepient JTable using the mouse scrollwheel before dropping the item. This would work if the frame was active. (I tested this by temporarily placing the two JTables in the same internal frame)

Thanks, this looks promising, unfortunately I read the stuff about glass panes but I can't seem to make it work anyway. As I understand it the default glass panes should block all events. This does not happen, even when I turn the glass panes visible on all JInternalFrames and the main JFrame. Everything is just like it was before... With this I mean that mouse events were sent to the mouse listener I added to the glass pane, but the mouse events also went to the underlying JInternalFrames. And when a drag'n drop was active, no mouse events are reported. What glass pane should I make visible for it to intercept all events?

Animation - when-mouse-move/enter or inserting an animated gif into the form

expecting some animation on oracle forms, eg. say if i move my mouse into the command button, it could change color(fr black to red). any idea? thank u.

In client server you can use the when-mouse-enter trigger to do that.
On the web you can use PJC like the sample "Browse RolloverButton PJC" you have on the sample code section of forms on otn.
On the web you can also embed animated gifs onto buttons as labels.

When-mouse-leave

db and dev 10g rel2 ,
hi all ,
i am trying to use when-mouse-leave for the first time , and i know that it fires when the mouse cursor leaves an item , and that is the functionality i want ,
i am trying to make an item invisible when i leave another one , so i did that ,
- two text items (t1, t2,t3) ;
using this trigger on a text item (t1) to make t2 invisible , when i leave t1 to go to (t3) ;
in the code i've written :
set_item_property('t2',visible,property_false) ;
it did not work , without any errors or messages ?. , -- this problem also happens with when-mouse-enter trigger ?
thanks

Post-text-item runs when cursor (focus) leaves the field. It runs when you click into another field, or use Tab or Enter to leave the field. I believe it also runs during query processing when data in the row is being populated by the fetch process.
When-mouse-leave in Client/Server Forms ran each time the mouse pointer rolled OUT of the field's perimeter. As you rolled the mouse pointer across the screen, LOTS of when-mouse-enter and when-mouse-leave triggers would run, if they were defined on all the fields, or at the block or form-level. We used it to pop-up a balloon-help display on items, if the user rolled the mouse into a field and waited ~half a second. When-mouse-enter / leave triggers do not run in web forms, so it will not cause excessive network traffic.
I cannot believe Oracle is so lazy that they haven't updated the online help.

Mouse enter/timer expired loses item focus

The triggers when-mouse-enter and when-timer-expired cause the current item focus to temporarily move to the module where the event was triggered if executing a multi-forms application. Also, if the user minimizes the application and he is using for example, Microsoft Excel, the cursor disappears because the focus goes to Oracle Forms due to this problem. This is irritating many users... Is there a workaround for this problem? I don't understand why this is necessary because these triggers are not interacting with any visual resource or instruction!
null

We had a similar problem but it turned out to be caused by a sychronize command within the trigger code rather the trigger itself.
In toher words it could be what you are doing and not the trigger itself.

WHEN MOUSE LEAVE in Client based

Hello,
I am upgrading some forms and facing some porblem while using WHEN_MOUSE_LEAVE trigger. Actually this trigger is not wokring. Could anyone please help me out in this matter.
Forms Verison : 6.0.8.12.1 (6i)
Many Thanks in advance.

email : [email protected]

Hi Duncan,
Yeah, I have put in debug codes at different points as have said. But form is not executing the WHEN-MOUSE_LEAVE trigger. With this I have also used WHEN-MOUSE-ENTER trigger, which is being executed properly.
Example: I have created one BUTTON with WHEN-MOUSE-ENTER and WHEN-MOUSE-LEAVE triggers, so when mouse enters on that button I am getting the results, but it not executing WHEN-MOUSE-LEAVE trigger, when mouse leaves that button.
Please help!!
Thanks & Regards

Mouse Enter/Exit Events

Hi,
I've got a question regarding mouse enter/exit events. Specifically, I would like to know why so many mouse enter/exit events are generated. Suppose you stack multiple Panes like this:
@Override
public void start(Stage frame) throws Exception {
 Pane root = new Pane();
 frame.setScene(new Scene(root));
 addEnterExitHandlers(root, "root");
 Pane fst = new Pane();
 root.getChildren().add(fst);
 addEnterExitHandlers(fst, "first");
 Pane snd = new Pane();
 fst.getChildren().add(snd);
 addEnterExitHandlers(snd, "second");
 Rectangle rect = new Rectangle(0, 0, 100, 100);
 snd.getChildren().add(rect);
 addEnterExitHandlers(rect, "rect");
 frame.show();
The addEnterExitHandlers() method simply registers event handlers for MouseEvent.MOUSE_ENTERED_TARGET and MouseEvent.MOUSE_EXITED_TARGET which print the event type's name together with the specified string.
The resulting output looks like this:
root MOUSE_ENTERED
first MOUSE_ENTERED
root MOUSE_ENTERED_TARGET
second MOUSE_ENTERED
first MOUSE_ENTERED_TARGET
root MOUSE_ENTERED_TARGET
rect MOUSE_ENTERED
second MOUSE_ENTERED_TARGET
first MOUSE_ENTERED_TARGET
root MOUSE_ENTERED_TARGET
root MOUSE_EXITED
first MOUSE_EXITED
root MOUSE_EXITED_TARGET
second MOUSE_EXITED
first MOUSE_EXITED_TARGET
root MOUSE_EXITED_TARGET
rect MOUSE_EXITED
second MOUSE_EXITED_TARGET
first MOUSE_EXITED_TARGET
root MOUSE_EXITED_TARGET
This output is not accurate, because I inserted empty lines to visually group related elements.
As you can see, a MOUSE_ENTERED event is fired for every node and all parent nodes receive MOUSE_ENTER_TARGET events. I just thought that it would be sufficient to only fire the last group of enter/exit events, respectively, i.e.:
rect MOUSE_ENTERED
second MOUSE_ENTERED_TARGET
first MOUSE_ENTERED_TARGET
root MOUSE_ENTERED_TARGET
rect MOUSE_EXITED
second MOUSE_EXITED_TARGET
first MOUSE_EXITED_TARGET
root MOUSE_EXITED_TARGET
Is there a specific reason for the behavior?
Best regards,
Matthias

Hi Matthias,
yes, there is a reason for this. In vast majority of use-cases, the entered/exited handlers are added on a node to handle the case when mouse enters/exits the node. The _TARGET variants tell you "this node or some of its children was entered/exited", which is not quite it. So right now, if you want to check that fst was entered, you just do:
fst.setOnMouseEntered(new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent e) {
 // your code
If we generated only the last group of events as you suggest, you would have to do:
fst.addEventHandler(MouseEvent.MOUSE_ENTERED_TARGET, new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent e) {
 if (e.getTarget() == fst) {
 // your code
Even if we added the convenience handlers for the _TARGET variants (setOnMouseEnteredTarget), having to always check the target would be pretty annoying.
Cheers,
Pavel

Enter key not working in forms 10g

Hi guys,
Enter key to select a form is not working
on my application.
I have to double click the form to open it using the mouse.
Then if we try to exit we have to press exit that many number of times as we have pressed enter key.
So it seems to be storing the key processes.
We are using forms 10g.
Please help.
Thanks and Regards,
Rohan

Fixed.
Changed KB.
However, this is still strange as the old KB was working fine in other applications.
