Does typing into an Input control raise an event?

9 posts in this topic

Hello

Is there an event for the user typing into a GUICtrlCreateInput() control?

I tried registering an event for an Input control but it does not seem to fire when text is typed into it. The event does fire when the GUI is destroyed, though. Other button and GUI events are working OK.

Regards

Nick

In your loop you could check it like this:

If $Input1 <> "" Then
; whatever you want to do
EndIf

This doesn't work perfectly because in the case you want to enable a button for example you have continuous enables as long as you type in the text in the input form

Thanls Sbad & Big Daddy

I guess I could use a flag in the loop to prevent continuous re-enabling, but I'd rather keep the loop clean if I can.

Something like this should work for that:

If Not $Input1 == "" And $Enabled Then
    GUICtrlSetState($Button1, $GUI_ENABLE)
    $Enabled = True
ElseIf $Enabled Then
    GUICtrlSetState($Button1, $GUI_DISABLE)
    $Enabled = False
EndIf

Need Beta for the following:

#include <GuiConstants.au3>

Global Const $WM_COMMAND = 0x0111
Global Const $EN_CHANGE = 0x300
Global Const $DebugIt = 1

GUICreate(" My GUI input acceptfile", 320, 120, @DesktopWidth / 2 - 160, @DesktopHeight / 2 - 45, -1, 0x00000018); WS_EX_ACCEPTFILES
$file = GUICtrlCreateInput("", 10, 5, 300, 20)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)
$input = GUICtrlCreateInput("", 10, 35, 300, 20)  ; will not accept drag&drop files
$btn = GUICtrlCreateButton("Ok", 40, 75, 60, 20)

GUISetState()
GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND")

$msg = 0
While $msg <> $GUI_EVENT_CLOSE
    $msg = GUIGetMsg()
    Select
        Case $msg = $btn
            ExitLoop
    EndSelect
WEnd

                Case $EN_CHANGE
                    _File_Changed()
            EndSwitch
    EndSwitch

Don't argue with an idiot; people watching may not be able to tell the difference.

Thanks gafrost

This looks like exactly the answer, but my beta installation is not picking up beta\Include\GUIConstants.au3 although the beta 3.1.1 (beta) file is there (and does contain new constants such as $GUI_DROPACCEPTED).

Have I missed out some vital step in configuring the beta installation?

Best regards

Nick

look at my sig, there's a link to the beta, believe the latest is 3.1.1.127

Edit: Also might want to look at useing SciTE (Alt+F5 runs the beta script, Alt+F7 compiles it)

Thanks - I already had the beta, but Scite > Tools > SyntaxCheckBeta throws warnings about the new constants. It is reading the Include\ folder instead of beta\Include\. I guess this is the default for the #include keyword. My apologies for making a meal out of this - I'm sure when I fix this issue your solution above will work great.
