Antonio,
thank you. Now painting is professional.
Would you be so kind to explain the difference between a
“control Classes” and a Class.
Thanks in advance

Otto,
A Class defines the properties and behaviors of a kind of objects to be created and managed. These objects don't need to be visible, i.e. a "customer", a "sale", a "payment".
A control Class is intended to create "visual" controls that can be placed on a window or a dialog or on top of another control. These controls can be placed in resources (RC files). i.e. a TButton, a TGet, or a TPickDate. These controls "inherit" from FiveWin Class TControl.

Calendars
Hi all
Its great to see the progress on and interest in Otto's very flash calendar control. I need a somewhat different calendar for my purposes and its certainly not as flash. There was a bit of a preview some posts ago in this thread. I don't want to clog up this thread, and my code is FiveLinux rather than FiveWin (although it wouldn't take much to "translate"). I've developed a bit more (not too much time at present) and have started a thread on it in the FiveLinux forum in case anyone is interested.
Its great to see the level of cooperation here. That can only help us all.
Regards
Doug

Hello FW Guru's!
I like the way it painted the screen when you resize the window.....
I love to see it in action with xBrowse.... and perhaps in dialogs too

Hello Antonio,Otto,
Could you please explain me whats the desired mouse behavior ?
1. A single click on a day and then change its color ?
2. To select a range of days and change their colors ?
3. To relate some sort of info with those selected days ?
Thank you very much for your work.
I made this picker to select a period of time.
Single click marks the start date.
Then you can move the mouse to the end date.
If you release the left button the period is selected.
Regards,
Otto

Desired Mouse Behaviour - A Suggestion
My suggestion is:
Single mouse click - select start point
Shift-mouse click - select end point
Leaving Ctl-mouse click as a toggle include/exclude if you ever want to support that.
Possibly more "standard" Windows? (although I have used Windows less than 2 hours in the last 6 months)

In this version you can select a range of dates clicking on a first date and then clicking on a second date. If you don't click on the second date, then only the first one is kept. Also if the second date is an earlier date, then the dates range swap:
