tedit change background color

hi all,
i am trying to migrate a couple of  application from xe2 to xe3 and i have this problem :

   r := ((codice_ricetta as tedit ).FindStyleResource('background') as TRectangle);
   if Assigned(r) then
       r.Fill.Color := TAlphaColorRec.Lime;

this code is working on xe2 but i receive this error on xe3 :

First chance exception at $751E277C. Exception class EInvalidCast with message 'Invalid class typecast'. Process Superv.exe (5916)

the background color do not change anymore.

there is a new metod on xe3 to do that?

thanks in advance

This assumes the 'backgound' style element is a TRectangle object. While this happened to be so for all the default styles in XE2, in XE3, it is a TSubImage for the 'platform' styles.

> there is a new metod on xe3 to do that?

No. Your best bet I think is to put the memo on a TRectangle of your choice, and make the memo background transparent -

((codice_ricetta as tedit ).FindStyleResource('background') as TControl).Opacity := 0;

This will then work regardless of whether the 'background' element is TRectangle or a TSubImage.

Hi Chris,

i solved in very simple way , starting from your Idea.

i need 3 color to show over the default one (red,yellow and green) , so the opacity method is not enough for my purpose.

i created 3   .png images with paint in 5 minutes.  (red,yellow and green matte images of course .... )  

i created the default  tedit styles configuration , and 3 more custom styles for tedit, each style in the source propertie load a timage associated to the 3 files.
the code now is very simple :)   :

     (codice_ricetta as tedit ).StyleLookup :=  'edit_lime_style';

     (codice_ricetta as tedit ).StyleLookup :=  'edit_red_style';

     (codice_ricetta as tedit ).StyleLookup :=  'edit_yellow_style';

the good of this is the freedom to load any kind of background image to the tedit object .

for next project i can reuse the style saved to external file.

Thank You

Datawindow status changed after background color changed
I have a problem on the datawindow After I changed the background color and tab order of a column, in debug mode, I find the column by using gettext and getitemstring to get the data after retrieved. I can get the current row number and current column name, however, using gettext() is returned empty string, but using GetItemString() is return the actual data of this column. why the reason is different? Gettext() returns the value that is in the edit control that "floats" over datawindow columns (as the user tabs along). Thus, gettext() returns a value that may have...

Changing Background color
Hey there , Just a quick question.Is there an easier way to programtically change the background color of a datawindow singleline edit control? What i've done so far is to code the itemfocuschanged event and use an IF THEN ELSE such as follows IF dwo.name="<fieldname>" THEN this.object.<fieldname>.background.Color=RGB(255,255....) ELSE this.object.<fieldname>.background.Color=RGB(255,255.....) END IF This works,however for forms with over 10 fields it can be tedious. When you say "Datawindow single line edit"...

Hello, Using the following syntax: dw_1.Modify("ls_columnname.Background.Color='65535'") does not work to change the background color through PowerScript.

Changing background colors
I have a cloumn that changes color based on the value of the column. Is it possible to get the windows default background color to set the color of the column, or do I have to hope that everyone always uses white? You can read the windows default background color from the background color of any object that has the background set to Window Background(like the window or any other controls on it). If you do not have any, just add a dummy text onto the dw and read its background color. -- SRLoka "Rich Vita" <LuvMe747@aol.com> wrote in message news:3OQs1MQ7AHA.194...

How to change the Background Color?
