Bugs in TextEditor: press [end] key, line break up and line spacing

  1. in TextEditor, press [end] key can’t reach the end of the line when the content is CJK text.

  2. There is no way to set line break up, so it will break up the content ahead of schedule when white space(s) blends in CJK characters.

  3. Request agian mightily:
    TextEditor::setLineSpacing (const float lineSpacing);



If I request an RichTextEditor based on WYSWYG, will I be killed? :worried:


no any help… It seems even worse than killed me…:no_mouth:


I have tried reproducing these issues with the Keyboard Viewer on Mac using different CJK languages but it seems to work fine. If you have any suggestions on how to fix these issues then I’d be happy to take a look.



OK, please try this text (Chinese mixed some English words for example):

editor->setMultiLine (true);
editor->setReturnKeyStartsNewLine (true);

  1. press [end] key or [cmd + ->] on mbp at any line.
  2. the wrong line break-up…


At the present, I can solve the wrong line break-up and increase the line spacing by hard-hack, it’s certainly a bad idea…so I hope juce-team could attach importance to these problems…

Solve the confusing of text line break-up of the default Editor when it blends Chinese charactors and English words (however, it’ll break up English word):

L227 in TextEditor, the ‘if’ statement need comment:

text.isWhitespace() &&

Increase line-spacing:
Same class above, L481 change the original to

lineHeight = section->font.getHeight() + 4;

L540 change the original to:

... atomX, (float) roundToInt (lineY + lineHeight - maxDescent - 2));

L573 change the original to:

... atomX, (float) roundToInt (lineY + lineHeight - maxDescent - 2));


Also, the default temp-underline of juce::TextEditor is too ugly and unbecoming, so I did this:

L560, underline change to backgound highlight:

//g.reduceClipRegion (Rectangle<int> (startX, baselineY, endX - startX, 1));
//g.fillCheckerBoard (Rectangle<int> (endX, baselineY + 1), 3, 1, colour, Colours::transparentBlack);
g.setColour (Colours::cyan.withAlpha (0.95f));
g.fillRoundedRectangle (startX - 1.f, baselineY - lineHeight + 10.5f, endX - startX + 2.f, lineHeight - 2.5f, 5.f);
drawSelectedText (g, underline, colour);


We’ve now added this to the TextEditor on the develop branch.



Thanks @ed95 !

Hope the problem of ‘press end key can’t reach the end of line’ will be solved soon… and setLineBreakup(...) will appear in JUCE lib…


Hi, @ed95

I tested the new method setLineSpacing(), but there’s still bugs there.

  1. New bug: after using the new method, the ‘down key’ wont work at all.
  2. press ‘end key’ still can’t reach the end of line, the caret will at the place of before the last character of the line.
  3. still break up the content ahead of schedule when whitespace(s) blends in CJK characters.

Please, please fix them… You can do it! come on ed95!!


And… if possible and without too much difficulty, could you add this method for TextEditor? just like the class CodeEditorComponent.

setColourScheme (const ColourScheme& scheme)


We’re all pretty swamped with JUCE 5 features at the moment so I can’t promise that this will get done any time soon. I’ll add it to the backlog but if you’ve got any patches that resolve these issues in the meantime then I can take a look.



Sadly… all I have to do just above, ed95.

It seems juce team will take these problems in the new version 5…

Don’t know why you guys don’t want a useful TextEditor which is so important for a modern C++ framework/library, so strange…
