Create a Panel width a text

[Silvio.Falconi]

I would like to create a Panel in a dialog with a large border and insert some text
the text is given by a memo field variable
and depending on the length of the memo the panel must be uniform, i.e. high for how many lines make up the memo

type this



I thought about creating a panel
but I didn't understand how to create a large border and at the same time update the height if the memo field is large compared to the initial space

[Detlef]

If you call the function MLCount() you know before how many lines your memo has.

[Silvio.Falconi]

If you call the function MLCount() you know before how many lines your memo has.

DEFINE BRUSH oBrushshadow GRADIENT aGrad //shadow
DEFINE BRUSH oBrushtext GRADIENT aGradtext //text


nTotRows:= MLCount(Alltrim(cmessage),250)

oPanel1 is a ttaskpanel

//the shadow
oItem1:=Tpanel():New( oPanel1:nTitleHeight +10, 10,;
oPanel1:nBottom-30,oPanel1:nWidth-40, oPanel1 )
oItem1:SetBrush( oBrushshadow )

//panel for the text
oItem2:=Tpanel():New( 2, 2,;
oItem1:nBottom-45,oItem1:nWidth-4, oItem1)
oItem2:SetBrush( oBrushtext )

//the text
@ 5,o10 SAY oMemo VAR cMessageMemo of oItem2 ;
SIZE oItem2:nwidth-40,oItem2:nBottom-10 PIXEL ;
FONT oFontText TRANSPARENT UPDATE



How I can calculate the nbottom of all tpanels with nTotRows ?

[Antonio Linares]

Dear Silvio,

You can use Windows API DrawText() using the flag DT_CALCRECT to calculate the dimensions of the text rectangle without actually drawing the text.
it will take into account the font you are using, etc.

The resulting width and height are stored in the rect structure.

Please look for DT_CALCRECT in FWH *.prg source code for code examples

yes,

I allredy found

DrawTextEx( ::hDC, cMessage , {nTop,nLeft,nBottom,nRight} )


but when I have the new cMessage ( edited) I must modify 3 controls on line

1. the TaskPanel
2. the first panel ( shadow)
3. the second Panel where is the text cmessage

and it is too hard

[Silvio.Falconi]

at init the Ttaspanel have the oPanel1:nBodyHeight = 100

If I made

Code: Select all  Expand view  RUN

Function RinfrescaPanel(cMessageMemo,oPanel1,oMemo)
   local nLineswidth:= 250
   local nTotRows:= MLCount(Alltrim(cMessageMemo),nLineswidth)
   local oItem
   local old_Height:= oPanel1:nBodyHeight


   oPanel1:nBodyHeight := (old_Height*nTotRows)/4

   for n = 1 to Len( oPanel1:aControls )
      oItem = oPanel1:aControls[ n ]
        if oItem:ClassName == "TTaskPanel"  .OR. oItem:ClassName == "TPanel"
         oItem:nBottom:=  (old_Height*nTotRows)/4
         oItem:refresh()
      Endif

      next

   oPanel1:refresh()
   return nil

 

why not refresh the oPanel1 ?

If I made

the Panel is modified and also the cMsg but the ttaskPanel is not refresh()

[Antonio Linares]

Dear Silvio,

You have to modify the oTaskBarPanel:nBodyHeight and call oTaskBarPanel:UpdateRegion()

[Silvio.Falconi]

Dear Silvio,

You have to modify the oTaskBarPanel:nBodyHeight and call oTaskBarPanel:UpdateRegion()

tried but it not refresh
if I collapse then it refresh


oPanel2:nBodyHeight:= aDim[ 2 ] + 50
oPanel2:CoorsUpdate()
oPanel2:UpdateRegion()
oPanel2:refresh()

result



also the text is not good i.e. is broken

[Silvio.Falconi]

any solution Please ?

[Silvio.Falconi]

Perhaps I found a solution

Code: Select all  Expand view  RUN

    oPanel2:nHeight     :=  aDim[ 2 ] + 50
    oPanel2:nBodyHeight := oPanel2:nHeight - oPanel2:nTitleHeight
    oPanel2:CoorsUpdate()
    oPanel2:UpdateRegion()
 

the Panel seems to change its size but if there is another panel after the modified one, if the dimensions are small a large space is formed between the panels, if the modified panel has a larger space it is drawn above the panel that follows

[Antonio Linares]

Dear Silvio,

Please post a screenshot, thanks
