WB12 - how to detect ENTER key in an edit control

Hi,

I need to know when the user pressed ENTER in an edit control.
I see some events like keyup,keydown and keypressed, on the browser side. But the KeyPressed() function is not available in WB.
how can I detect which key is pressed ?

Hi Arie

in some of the programs here we use to determinate the <F12> button to print a printscreen

what do you need=
1 in the project initialisation set the next lines:
EXTERN "winconst.wl"
EXTERN "keyconst.wl"
keyconst is needed voor the key ,,,

on the screen where you want to trigger create a local procedure, we use tehe global procedure printscreen,, to print the screen

FUNCTION lp_CheckKey(p_Mess is int, p_Par1 is int, p_Par2 is int)
Info(p_Par1) // here you get the number of any key you stroke
IF p_Par1 = 123 THEN //Functietoets <F12> ingedrukt
EndEvent(gv_EventPrint)
gp_PrintScreenLandscape(Handle(), "Web_UbenchInfo.IMG_ExpAfdruk" )
gv_EventPrint = Event("lp_CheckKey", "*.*", WM_KEYDOWN)
END


at the declaration section of that windew create the globale variabele
GLOBAL
gv_EventPrint is int = Event("lp_CheckKey", "*.*", WM_KEYDOWN)



that's all!

Marc,
unfortunaltely this does not work in webdev, only in windev.
I was looking for a webdev solution.

Hi Arie...

You need to use javascript code to do that... If you don't find it, lt
me know, I have that somewhere (just need to remember where :-) )

best regards

Fabrice,
I (Google) found lots of examples on "javascript detect key pressed". I tried a few things, but I'm new on javascript (and W.

I'm able to create an event handler, which should give me an event-object, holding a 'keycode'. But this event-object is always null in my case....

For now I use a hidden link-control. It has a property "Use 'Enter' as shortcut". Not so nice, but it works.

So: if you can find your example, please post it here.

Hi Arie,

I believe you want to put the following JS code in the "onkeypress" event of your edit control:

e=(document.all? event.keyCode:event.which);
TestIfEnter(e);

Fabrice gets the credit- I just found it quicker.

please have a look in the WEBDEV forum where I posted an answer about the ENTER key...

create a browser procedure in Javascript, and call it from the keyPressed browser process of the edit control.. the following would return true if enter key is pressed.

function enterPressed()
{
var evnt = event || window.event;
var code = evnt.charCode || evnt.keyCode;

return (code == 13);
}
