Pickdate

Here you have the PRG (with some more changes) and the EXE:

A little obvious typo:

Code: Select all

   METHOD  PreviousYear() INLINE ::nYear--, ::Refresh()
   METHOD  NextYear() INLINE ::nYear++, ::Refresh() 

[Antonio Linares]

Some gradients to make it nicer

Antonio,

thank you very much.
Now I will try to get the functionality I had (MOVEMOUSE) into the new class design.
Regards,
Otto

[Antonio Linares]

Otto,

What do you need mousemove for ?

If you want to change a dates range, maybe we could use right click, or similar.

The easier you make it for the final user, the better.

[Otto]

Antonio, here is what I want to do.

Otto

I think Otto want the user can select from a date to another with the mouse , the movement must colorize the box where there are the numbers of the days

When the user not press the click the mouse the procedure must return how many day he selected from date a to date b

Right, Otto ?

[Andrés González]

Antonio and Otto would you mind the possibility to include and aPrompt and aBmp in the tPickData class.

[Silvio]

Dear Andres,
before the mousemose movement is max important
then we can think to insert bitmaps or ctext

[Andrés González]

Thanks Sylvio, just an idea.

Hello Antonio,

I tried to insert mousemove in the control class design.
I works but performance is bad. The class I had performs much better.
Is this normal that a control is slower or did I made a mistake by inserting the mouse move method.
Would you be so kind to check the code. Thanks in advance.
Otto

Otto,

You only have to call ::Refresh() and not ::Paint().

::Refresh() will request a paint.

[James Bott]

Otto,

Although calls to Paint() and Refresh() will work they are going to be slow. For speed, what you want to do is redraw only the old highlight (as unhighlighted) and the new highlighted area--not the entire screen. Right now you are redrawing the entire screen twice for each mouse movement.

For ideas how a similar MouseMove() works, take a look at TWBrowse(). Note that it inherits from TControl which inherits from TWindow, so take a look at the MouseMove() methods in those classes also. I am not saying that your MouseMove method should work the same as TWBrowse's, but you can see how it processes the information and when it calls the parent class.

Note also that your MouseMove() method should return 0 not nil.

Hello Antonio, hello James,

I eliminated the call for Paint method.
But with not much success. The painting of the days is very slow.
I turned off double buffering. You can see how the rows get painted.

In my wrapped class design the painting is optimal . Please see the video or try the exe.

I can’t find out the problem in the new code.

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.

Otto
