Text select Color

[paule32]

Hello,
I would colorize some parts of Text.
So I had try some dirty hacks, and I am fail.
The Question is, how can I mark parts of Text in an other Color than the normal Text Color ?

{
    static bool oooo = false;

    if (event.what == evKeyDown) {
        if (event.keyDown.keyCode == kbLeft) {
            if ((event.keyDown.controlKeyState == 0x0310)
            ||  (event.keyDown.controlKeyState == 0x0110)) {
                clearEvent(event);
                
                selecting = true;
                selected  = true;

                static uint xpos ;
                static uint ypos ;
    
                if (!oooo) {
                    xpos = cursor.x;
                    ypos = cursor.y;
                    oooo = true;
                }
                
                selEnd   = xpos;
                selStart = cursor.x;
                
                Color    = EditorCommentColor;
                
                setCursor(cursor.x - 1, cursor.y);
                xpos = xpos - 1;
            }   else {
                oooo     = false;
                selEnd   = 0;
                selStart = 0;
                
                Color    = EditorTextColor;
            }
        }   else
        if (event.keyDown.keyCode == kbCtrlS) {
            clearEvent(event);
            messageBox("ctrl + s",mfInformation|mfOKButton);
            return;
        }
    }

    TFileEditor::handleEvent( event );
}```

These hacks are no good. You only have two options:

• To store styling information in a separate data structure, as you did in Get Color, under the Cursor's character item ? #151 (comment).
• To decide everything while drawing the view in draw() (or maybe formatLine() in your case).

For example, the original TEditor simply applies the following logic:

1. From the document's beginning to selStart, draw using the normal text color.
2. From selStart to selEnd, draw using the selected text color.
3. From selEnd to the document end (bufLen), draw using the normal text color again.
