How to bring transparent background to CEikRichTextEditor

[TeachMe]

Hello Nokia forum User,

I am developing one project using CEikRichTextEditor , but I am facing some problems.

(1) I am getting a white background . If we can change then would we able to change the white to some other user defined color. (I would be happy if I am able to get a transparent background)
(2) The font color is green in color by default. How can v change this .
(3) I have given in OfferKeyEventL (.. Page/Line up movement for the cursor, evenif only the last line gets folded by itself. No movement by page/line .

Pls help me by providing some useful tips and stuffs

Thanks in advance
with regards.

1) Check that your code supports themes. You AppUi ConstructL code should start like this:

BaseConstructL(EAknEnableSkin);

// Create view object
iAppView = CYourView::NewL( ClientRect() );
iAppView->SetMopParent(this);
AddToStackL(iAppView);

Your container should contain following variable:
MAknsControlContext* iBackGround; // for skins support

Your container needs to create iBackGround in ConstructL:
iBackGround = CAknsBasicBackgroundControlContext::NewL( KAknsIIDQsnBgAreaMain, Rect(), EFalse );

And you need to implement background drawinf in your containers Draw-function:
void CYourView::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
// TODO: Add your drawing code here
// example code...
MAknsSkinInstance* skin = AknsUtils::SkinInstance();
MAknsControlContext* cc = AknsDrawUtils::ControlContext( this );
AknsDrawUtils::Background( skin, cc, this, gc, aRect );
}

After this all contained controls should be "transparent" by default.

2) I'll just copy some of my code here:
TCharFormat check;
TCharFormatMask charFormatMask;
const CFont* font = AknLayoutUtils::FontFromId(EAknLogicalFontTitleFont);

AknLayoutUtils::FontFromId(EAknLogicalFontPrimaryFont);
check.iFontSpec = font->FontSpecInTwips();
charFormatMask.SetAttrib(EAttFontStrokeWeight);
charFormatMask.SetAttrib(EAttFontPosture);
charFormatMask.SetAttrib(EAttFontUnderline);
charFormatMask.SetAttrib(EAttColor);
MAknsSkinInstance* skin = AknsUtils::SkinInstance();
TRgb textcol;
AknsUtils::GetCachedColor(skin,textcol,KAknsIIDQsnTextColors,EAknsCIQsnTextColorsCG6);
--> check.iFontPresentation.iTextColor = TLogicalRgb(textcol);

text->ApplyCharFormatL(check,charFormatMask,iEditor->CursorPos(),aText.Length());

This sets the color that theme developer has suggested to be the main pane text color. Just change the line marked with an arrow to change the text color to any value you wish. (this code contains some unnecessary stuff for your use, just use the bits you need)

3) Could you clarify your question?

Hello,

I was able to solve the 3rd problem

thanks

Your container needs to create iBackGround in ConstructL:
iBackGround = CAknsBasicBackgroundControlContext::NewL( KAknsIIDQsnBgAreaMain, Rect(), EFalse );

Hello BitNir,

I have done as you said. But for the first line itself it works fine. ( That too an editor created thru resource.) If I trid to create an editor by coding , its background will not be transparent.

Where is the variable iBackGround further called. I don't know .Pls clarify my doubts.

Thanks in advance

Hey bitnir,

I tried as you said to make the background transparent for a CEikRichTextEditor. But its not working for me. Could you kindly tell me if I need to change somewhere else also to make it done ?..

With thanks
