Pickdate

[James Bott]

Otto,

James you are right with you advice to repaint only the changes. But that is much more work.
And as the whole repainting in my initial project works so well I don’t think it is necessary.

Can you just use the same paint code from your original project in the Paint() method of the new class?

James

[Otto]

Hello James,

As so many times i posted my request not very clearly.

What I would like to know is:
Could a “control class” be as quick as a “stand alone” class. I don’t know if this is the right term.

Should I have - theoretically doing all the code the right way - the same results or is there some overhead in a control class which you can’t bypass.

oWnd:oClient = oPickDate
CLASS TPickDate FROM TControl

I can’t imagine that all this comfort does not consume speed. Therefore I started my pickdate as a own window.

Regards,
Otto

[Antonio Linares]

Otto,

Using your painting method, place the calculator on top on your window, move it and see if it is ok or not.

[Otto]

Antonio,

what do you mean by move?

If I click in the title and press the left mouse button then I can move the whole picker without any flickering.
Also if I move another window over the picker it repaints without flickering.
I can not resize because I have not implemented.

But I have no problem with the “control class design” speed if I know that I have to care about speed.
There are many possibilities to reduce the amount of necessary re-paintings.
The first I would try is to re-paint only if the mouse moves to another day.

Regards,
Otto

[Antonio Linares]

Otto,

I mean to move the calculator over the pickdate window.

Just curious to know how it behaves.

[Otto]

Antonio,
there is no problem.
I uploaded my exe to:

http://www.atzwanger.com/fwtests/testpickdate.zip

[Antonio Linares]

Otto,

Yours is painting nicely

Do you repaint the entire surface or just the selected days ?

[Otto]

Antonio,
Here I post my code again.
I do not see much different except the control class design and that my code is a little unstructured.
Maybe you can find out the difference.

Regards,
Otto

Dear Otto,

Your method DrawRowLines() is quite scaring

You should try to structure it into smaller functions calls to get a cleaner and better maintainable code

[James Bott]

Otto,

I ran the test control class and I find that the hourglass cursor is running continuously. This means it is in a continuous loop and this is the main reason for the slow performance. I do not know where this loop is.

James

[Silvio]

I propose to change something.
this is my idea
to create a control ok to ownd and for odlg

i think to create array items x,y to move the mouse x,y mounth(X),day(Y)
the user can move the mouse and colorize or dotted( rectangule dotted) and select how many day he wants,
but i not know how i can create

i hope antonio understand me

[James Bott]

Antonio,

I have searched the FWH PRG source for an oocurance of the hourglass cursor (cursorWait()) and I cannot find one. Is this cursor either created using other syntax or possibly in the C source? If so, do you have any idea where?

I am trying to find the continous loop that is occuring in Otto's TPickDate class that is showing the hourglass cursor. Any ideas where this might be happening?

James

[Otto]

Hello James,

I too noticed this. But then I looked into task manager and the CPU consumption.
Although you see the hourglass there is no consumption.
If you resize the control then the resize cursor remains.
Regards,
Otto

James, Otto,

If MouseMove() is redefined then a final call to Super:MouseMove() should be done as one of its tasks is to properly set the mouse cursor.

Thank you Antonio,

Is this the right place and way to insert Super:mouseMove().
If yes, it does not resolve the painting problem.
Regards,
Otto

Code: Select all  Expand view

METHOD MouseMove( nRow, nCol, nKeyFlags ) CLASS TPickDate
   if ::lMove = .t.
      ::syTemp := Int( ( nCol - 60 ) / ( ( ::nWidth - 60 ) / 37 ) ) * ( ( ::nWidth - 60 ) / 37 )  + 60   + ( ( ::nWidth - 60 ) / 37 )
      IF ::nRowCol<>::syTemp
         ::nRowCol := ::syTemp
         ::refresh()
      ENDIF
   endif

   Super:MouseMove( nRow, nCol, nKeyFlags )

return 0
