GUI Keyboard Input

Recommended Posts

Artisan

I am creating a GUI that uses mostly GDI work, and a few standard controls. This is the same one that I posted about >before. When my GUI has focus, I want to watch for the user to press the numbers 1-9. I do not want to monitor keyboard input when the GUI does not have focus. There are multiple ways to do this. Here are my ideas so far:

  1. Use _IsPressed. Currently I'm using the standard GUIGetMsg() loop, but I could easily convert to GUIOnEventMode and poll _IsPressed continuously. I haven't tested yet, but I assume it fires whether or not the GUI has focus. That's easy to watch for, though.
  2. Register WM_KEYUP. Oh how I wish that GUI controls didn't hog this message for themselves! The only way to make this work is to convert my GUI controls into "manual GDI controls" that I draw & manage myself. Then the GUI itself will receive WM_KEYUP (etc) messages. (I've already tested that with an empty GUI.) For GUI controls, all I have is a Tab control with a button on the first tab, and 2 buttons and a ListBox on the 2nd tab. Given the GDI work I'm already doing, it wouldn't be that much more work to make it happen. It also gives me more control over the style and look of things.
  3. Use HotKeySet. I would have to set and unset all 9 when the GUI gains/loses focus. This doesn't seem like the most elegant solution, but it's a good fall-back.

Technically, I could hook the keyboard, but that's really shady and goes way beyond what I need. I'm not going to do that.

So, which way is "best"? How do you define "best"? I think #1 is my best option, but I want to know what everyone else thinks and why. Maybe there's a better way? I doubt I've thought of everything. ;)

Artisan,

Have you thought of Accelerator keys? They are only active when your GUI is active - sound like just the job. ;)

GUISetAccelerators is the function you need. ;)

      Hello everyone,
      I have a radio button ($Radio1), which I want to disable as soon as another one get's checked (Radio5). (The system fails if the radio button i'm troubling with also gets checked).
      I know how to disable him:
      If GUICtrlRead($Radio1)=1 And Not BitAND(GUICtrlGetState($Radio5), $GUI_DISABLE) Then GUICtrlSetState($Radio5, 128) But if i try to enable $Radio5 again, after $Radio1 isn't checked anymore, it fails:
      If GUICtrlRead($Radio1)=Not 1 And Not BitAND(GUICtrlGetState($Radio5), $GUI_ENABLE) Then GUICtrlSetState($Radio5, 64)  
      Anyone knows why?

      Good evening everyone
      First, I want to apologize with you for the title not very clear, but I thought a little bit on which title to set at the thread, and this is the one that came in mind.
      Now, let me explain what I'm trying to understand.

      I am making an application ( with n clients ), with an SQLite Database, which has a Main form, and n sub-forms... 
      Since these sub-forms are called several times, because they are used to add or update records to the Database, I put the code that generates the GUI of these sub-forms in Functions.
      There are two sub-forms which are "treated" as two main forms, since even them have n sub-forms, which perform various tasks.
      Where am I stucked?

      For the Main form I created a Status Bar, in order to display messages ( add/delete/update/search results ), and it works perfectly with all the forms which don't have other sub-forms.
      For the two forms, which indeed have n sub-forms, I created two separated Status Bars, which are (re)created everytime I call the function that then displays the form.
      Practically, I can't set icons to these two Status Bars, and I don't know why.
      I'm really sorry that I don't feel clear enough, so, here you are an example of what I am saying.
      I recreated exactly what my script does:
      #include <GuiButton.au3> #include <GUIConstantsEx.au3> #include <GuiStatusBar.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) Global $frmSubForm, _ $txtSubFormField, _ $sbSubFormStatusBar, _ $objSB_IconError = _WinAPI_LoadShell32Icon(109), _ $objSB_IconInformation = _WinAPI_LoadShell32Icon(277) #Region ### START Koda GUI section ### Form= $frmMainForm = GUICreate("Main Form", 300, 300, -1, -1) GUISetOnEvent($GUI_EVENT_CLOSE, "ExitApplication") $sbMainStatusBar = _GUICtrlStatusBar_Create($frmMainForm) $btnCreateSubForm = GUICtrlCreateButton("Create Sub Form", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "GenerateSubForm") GUICtrlSetFont(-1, 10, 400, 0, "Arial") _GUICtrlStatusBar_SetSimple($sbMainStatusBar) _GUICtrlStatusBar_SetText($sbMainStatusBar, "") GUISetState(@SW_SHOW, $frmMainForm) #EndRegion ### END Koda GUI section ### While 1 Sleep(100) WEnd Func ExitApplication() Exit EndFunc Func GenerateSubForm() #Region ### START Koda GUI section ### Form= $frmSubForm = GUICreate("Sub-Form", 300, 300, -1, -1, -1, -1, $frmMainForm) GUISetOnEvent($GUI_EVENT_CLOSE, "DeleteSubForm") $txtSubFormField = GUICtrlCreateInput("", 0, 0, 100, 20) $btnCheckSubFormField = GUICtrlCreateButton("Check Field", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "CheckSubFormField") GUICtrlSetFont(-1, 10, 400, 0, "Arial") $sbSubFormStatusBar = _GUICtrlStatusBar_Create($frmSubForm) _GUICtrlStatusBar_SetSimple($sbSubFormStatusBar) _GUICtrlStatusBar_SetText($sbSubFormStatusBar, "") GUISetState(@SW_SHOW, $frmSubForm) GUISetState(@SW_DISABLE, $frmMainForm) #EndRegion ### END Koda GUI section ### EndFunc Func DeleteSubForm() ; Declared Globally => $frmSubForm GUIDelete($frmSubForm) GUISetState(@SW_ENABLE, $frmMainForm) EndFunc Func WriteToStatusBar($sbStatusBar, $objSB_Icon, $strText) _GUICtrlStatusBar_SetIcon($sbStatusBar, 0, $objSB_Icon) _GUICtrlStatusBar_SetText($sbStatusBar, $strText) ConsoleWrite("Icon Handle: " & $objSB_Icon & @CRLF) EndFunc Func CheckSubFormField() ; Declared Globally => $txtSubFormField If GUICtrlRead($txtSubFormField) = "" Then ; Declared Globally => $sbStatusBar WriteToStatusBar($sbSubFormStatusBar, $objSB_IconError, "Field NOK.") Else WriteToStatusBar($sbSubFormStatusBar, $objSB_IconInformation, "Field OK.") EndIf EndFunc The text is set, but icon is not.
      Could someone please tell me why?
      Thanks everyone in advance  

      Best Regards.

      Hi, everybody
      I look for GUI whose behavior similar to the message of an email client or antivirus
      In other words:
          Any PC screen able to calculate the size
          To consider the Task bar size
          To find the lower corner on the right/below and to nestle on it

      Notes:
      In GUI the GUICtrlCreateEdit field (as option) - that can be received and displayed through variable information
      Thanks a lot
      PS
      I use the translator, excuse if something is not clear
