I can't get focus properly on keyboard, somehow to get focus I need to do a click first with mouse, then it can read keyboard ONCE!!, I need it to get the keyboard keys anytime "not just once, or by a refreshing mouse click"

  
Bool SNodeUserArea::InputEvent(const BaseContainer& msg)
{
	Int32 dev = msg.GetInt32(BFM_INPUT_DEVICE);
	Int32 chn = msg.GetInt32(BFM_INPUT_CHANNEL);
  
	if (dev == BFM_INPUT_KEYBOARD)
	{
		GePrint("key pressed");//prints only if I press mouse before keyboard...
		if(chn == KEY_DELETE)
		{			
			BaseContainer actionk(BFM_ACTION);
			actionk.SetInt32(BFM_ACTION_ID, GetId());
			actionk.SetInt32(BFM_ACTION_VALUE, 0);
			actionk.SetInt32(BFM_ACTION_UPDATE, true);
			
			removeSelectedNodes();
			removeSelectedWires();
			InvokeCommandCall(GetDialog(), COMMANDMSG_VALUECHANGED);
			SendParentMessage(actionk);
			return true;
		}
	}
	else if (dev == BFM_INPUT_MOUSE)
	{  
            ...  
        }  
        return false;  
}

Hello,

what exactly are you doing in InvokeCommandCall() and what consequences does SendParentMessage() have? Do you also loose the focus if you don't call InvokeCommandCall()?

Best wishes,
Sebastian

here is what I do:

  
static Bool InvokeCommandCall(GeDialog* dialog, Int32 id) {
    BaseContainer actionmsg(BFM_ACTION), actionresult;
    actionmsg.SetInt32(BFM_ACTION_ID, id);
    return dialog->Message(actionmsg, actionresult);
}

in iCustomGui subclass:

  
    virtual Bool Command(Int32 id, const BaseContainer& msg) {
        if (id == COMMANDMSG_VALUECHANGED) {
            SendValueChanged(this, msg);
        }
        return TRUE;
    }

  
static Bool SendValueChanged(iCustomGui* dlg, BaseContainer msg) {
    msg.SetInt32(BFM_ACTION_ID, dlg->GetId());
    msg.RemoveData(BFM_ACTION_VALUE);	
    msg.SetData(BFM_ACTION_VALUE, dlg->GetData().GetValue());
    //GePrint("just msg " + String::IntToString((static_cast<iSnodeDataType*> (msg.GetData(BFM_ACTION_VALUE).GetCustomDataType(SEVENPHOTONS_NODE_CUSTOMDATATYPE)))->count));
	return dlg->SendParentMessage(msg);
}

which is simply updating my CustomDataType members, so if user interacts with GeUserArea, InvokeCommandCall() is the update function.

if I remove InvokeCommandCall() , there is a delay, but it works without a problem, what should I do?

Hello,

why are you sending a message in InvokeCommandCall() and then again with SendParentMessage()? Typically one uses SendParentMessage() to inform the parent dialog that something changed. See the example on GitHub.

I see, but the problem remains "I removed all calls to SendParentMessage(), all calls now are InvokeCommandCall()"

Hello,

actually I would have suggested to remove that InvokeCommandCall() stuff and just send the SendParentMessage() to react accordingly when you catch that message.

Hi Sebastian,
I know that was a little old, but I reworked the code and did many tests to see where the problem is.
now what I can confirm: (attached a piece of the code..)

  
Bool SNodeUserArea::InputEvent(const BaseContainer& msg)
{
	Int32 dev = msg.GetInt32(BFM_INPUT_DEVICE);
	Int32 chn = msg.GetInt32(BFM_INPUT_CHANNEL);
	GePrint("any event!!");
  
	if (dev == BFM_INPUT_KEYBOARD)
	{
		GePrint("any key is pressed");
		if(chn == KEY_DELETE)
		{
			if (!selection)
				return true;
  
			BaseContainer actionk(BFM_ACTION);
			actionk.SetInt32(BFM_ACTION_ID, GetId());
			actionk.SetInt32(BFM_ACTION_VALUE, 0);
			actionk.SetInt32(BFM_ACTION_UPDATE, true);
			
			removeSelectedNodes();
			removeSelectedWires();
			//InvokeCommandCall(GetDialog(), COMMANDMSG_VALUECHANGED, actionk);
			SendParentMessage(actionk);
			return true;
		}
	}  
......

the problem is:
after a mouse click "for example selecting a node in my userarea" , this changes the data of my CustomDataType, once this is done, the focus is gone!

so next keyboard hit is missing "the whole InputEvent() is not called at all!" , so I have to click again.
I also tested it with your example, your example works fine!, the only difference that I see is: in many cases I may send multiple parent messages... "is this a problem?"

though I hacked around it, not sure if this is fine or not "you may tell " , I set:
action.SetInt32(BFM_ACTION_UPDATE, true);

this forced it to work! , so if this is fine you can consider this solved or suggest a better alternative

ok I found a pitfall!!, action.SetInt32(BFM_ACTION_UPDATE, true); actually updates immediatly BUT ignores the data change update "so the GeUserArea updates, but the internal data doesn't get a refresh "as this user area can be seen in multiple object managers, I see it only updating in 1 location when action.SetInt32(BFM_ACTION_UPDATE, true); is active!"

on the other hand without this line, it got the keyboard delay focus, ideas?

Hi Mohamed,

Sorry for my late reply.
Sebastian will be back next week and I'm sure he'll be able to give you feedback and ideas for your problem.

Hello Mohamed,

your last posts are a little bit confusing. Can you post your current code of all relevant classes and functions?

Best wishes,

Hi Sebastian,

I guess the functions are getting delayed due to heavy processing "when the MatPreview is rendering the this problem happens!".

so I guess it is a wait for event loop that get ignored due to thread being busy in rendering.
but the problem as I posted, and the code is quite complex!! "more than 7k lines../+ I can't strip it ".

Hello,

I do not understand how material preview rendering is related to this thread. Without more specific information I don't think it is possible to give more help.

He Sebastian,

it is a long story "this GeUserArea is a custom gui for a custom data type inside my MaterialData plugin".
but I tested when rendering is off too, it didn't work for unknown reason, I guess I will accept the result anyway.

you can consider this solved/closed.
