Can I add a hotkey

[fiscal]

Is it possible to add a custom hotkey that I can invoke when the ActiveX control has focus.

The wish is to invoke some clarion code when a document is active in the ax control.

I am revisiting a way to copy pages from one document to another, behind the scenes.

When I select some pages in the thumbnail list, I wish to be able to press a function button, say F2, and it will extract the pages from the active document and append them into another file, and add some notes about the additional pages in another data file. The code to do this is OK, but I just cannot seem to invoke the altered key when the control has focus.

Thanks

Hello Tony,

If it is your main application window that has the focus, and is listening for key strokes - you can set up any hotkeys - and make them execute any commands available through the AX SDK. However it is not possible to add custom hotkeys inside the AX control for combined or multi step commands.

Hi Stefan,

If I add a hot key to the window, say F2. I cannot execute that hotkey, unless I click on an area of the window other than the AX control.

I do have code under a button to perform what I need, but it would be easier on the user if they can also use a hot key.

So, from what I think you are saying, if the AX control has a document open and has focus, then the hotkey will not work?

See ya

Hi Tony,

Actually looking through the AX Manaul, you could intercept a key stroke - and execute any set of commands you like:

Code: Select all

function OnEvent(Type, Name, DataIn, DataOut, Flags)
{
   if (Type == PXCVA_OnNamedNotify) and
      (Name == "Notifications.Keyboard") thenPDF-XChange Viewer SDK 174
   {
      // Get keyboard event message
      GetProperty("Notifications.Keyboard.Code", vDataOut, 0);
      if (vDataOut == 71) then //F2 Key pressed
      {
         //Perform any commands you would like
      }
   }
}

P.S. Also if you wish to skip the default processing of the key by the Viewer (if there is any - as F2 by default does not have an action assigned) - also make sure to include
SetProperty("Notifications.Keyboard.Skip", "true", 0);
before the return of your event handler.

Best,
Stefan

Thanks Stefan,

Where would I place such code to trap the keystroke? I could not locate the onevent stuff in my documentation.

Thanks

Hello Tony,

I am not sure how this will look in Clarion, so I will need to speak with Craig, but if you do not have the latest build of our Viewer SDK - make sure to download it - the documentation and samples should have an event handling sample - the non clarion code samples certainly do.

Best,
Stefan

Hi Stefan,

I have the latest download, and I cannot find it, but if it is in version 3 then I will be happy....

Hi Tony!

I think I know what Stefan is referring to. It may not be in the Viewer SDK 2.x docs.

I may be able to modify the Viewer's Clarion Class files to trap the keystrokes. I'll need some time to check this out.

Thanks Craig,

I have to wait for version 3 for the code command to fire up the NewDocumentFromScanner method, so it can wait until then.

See ya

Hi Craig,

This topic is interesting me. Is it already possible to trap keystrokes in the class files? That would be great. Especially if it would be possible to replace the default shortcuts. Some of the shortcuts used in the AX control are also used in my application but with a different function.

That might be confusing for the user

Hi Koen!

I tested this but found that it does not perform as advertised. It is SUPPOSED to be working in version 3, but I have no estimated release date for that version.

Hi Craig,

Well you gain some, you lose some. I guess we have to wait a bit longer for this possibility.

Thanks,
