Pickdate part 2 – a control class in development

[quique]

Congratulations Otto, and the all people that help to obtain this great job

[Kleyber]

Does this function work with FWH 8.02? I am trying here but there is no GradientFill() function.

Regards,

Hello,

The new Gradient-function comes with FWH-Version 8.07
There is a Gradient-function in older versions.

before Version 8.07, i created a gradient-brush for
bmp's or backgrounds :

aRect := GETCLIENTRECT( oBmp:hWnd )
nGRADIENT := Gradient( hDC, aRect, nVColor, nBColor, .T. ) // .T. Horizontal
or
nGRADIENT := Gradient( hDC, aRect, nVColor, nBColor, .F. ) // .F. Vertical
oBmp:oBrush := TBrush():New( , nGRADIENT )
FillRect( hDC, aRect, oBmp:oBrush:hBrush )

I do not know, if this can transported to Otto's functions,
because i do not know them in detail for the moment.

Best Regards
Uwe

Hello Kleyber,
please delete the lines with GradientFill or comment them.

//GradientFill( hDC, 0, 0, ::nHeight, ::nWidth, { { 1, nRGB( 128, 217, 255 ), nRGB( 54, 147, 255 ) } } )

They are not necessary for the pickdate function.

Otto

Uwe,

Thanks for information.


Otto,

Thanks!!

Antonio,

Thanks for response. After commenting those lines, the dialog shows all the days in BLACK (foreground and backgroud). Only the SUNDAYS are with the correct color. How can I solve this?

Regards,

Kleyber

Otto ,
in resource test if we ren gradientfill I not see nothing... I see black box
I not have this func

[nageswaragunupudi]

GradientFill( hDC, 0, 0, ::nHeight, ::nWidth, { { 1, nRGB( 128, 217, 255 ), nRGB( 54, 147, 255 ) } } )

is functionally equivalent to

Gradient( hDC, { 0, 0, ::nHeight, ::nWidth }, nRGB( 128, 217, 255 ), nRGB( 54, 147, 255 ), .t. )

You may use simple Gradient function if you are using an older version of FWH

Hello Antonio,

How would you suggest to insert controls to navigate the date?

Should the controls be in the new/redefine method and the paint method changed the way,
that the “clearscreen”: FillRect( hDC, GetClientRect( ::hWnd ), ::oBrush:hBrush )
would not clear the controls?

Regards,
Otto

Otto,

I would place two buttons, one on each side of the year.

They could be TButton, TBtnBmp or TButtonBmp.

We can create them in the new method once the handle of the control pickdate already exists. For Redefine(), Method Initiate() has to be redefined.

[Otto]

Antonio,

local aInfo := ::DispBegin()
::DispEnd( aInfo )

clears the whole screen.

How can I protect the buttons from cleaning?

Thanks in advance
Otto

Otto,

Add these lines in method new:

Code: Select all

   if ! Empty( oWnd:hWnd ) 
      ::Create() 
      oWnd:AddControl( Self ) 
      @ 4.2,  5 BUTTON "<" OF Self SIZE 20, 20 ACTION ::PreviousYear()  // new
      @ 4.2, 20 BUTTON ">" OF Self SIZE 20, 20 ACTION ::NextYear()  // new
   else 
      oWnd:DefControl( Self ) 
   endif 

return self 

Those buttons don't use double buffer painting, so they will flicker if the PickDate control is resized.

[Otto]

Thank you, Antonio.
Do you think there is another solution.
The flickering is not very nice. Also if you move the mouse there is a flickering.

Regards,
Otto

Otto,

Class TBtnBmp does use double buffer painting. Lets try with them...

[Antonio Linares]

Otto,

This fix is required for Method MouseMove() as we are repainting the control on each mouse move! We should repaint it only when an initial date has been selected:

if ::lMove .and. nDay > 0 .and. nMonth > 0 // to work with valid dates only
