Re: [orion-dev] CodeEdit change font size
Hi Libing,

your proposed solution didn't work for me as I don’t use the "themeClass" but the "theme" attribute (FYI: it did work when using the themeClass attribute, but that would mean I have to include the corresponding CSS file on all of my editor pages) and it is not dynamic enough for my needs. However, I did some experimenting and came up with the following idea (but with a catch):

// setup (same as before)
function loadTheme(themeName) {
var theme = mTextTheme.TextTheme.getTheme(themeName);
if (!theme.getThemeClass()) {
theme.setThemeClass(themeName, { href: 'CodeEditWidget/themes/' + themeName });
}
return theme;
}

var theme = loadTheme('prospecto');

codeEdit.create({ parent: 'editor' }).then(function(editorViewer) {
editorViewer.editor.getTextView().setOptions({
theme: theme
});
});

// on zoom value change
var stylesheet = theme.buildStyleSheet('prospecto', { className: 'prospecto', styles: { 'font-size': fontSize + 'px' } });
theme.setThemeClass('prospecto', stylesheet);


Although this works for setting the font size (without artifacts), the Prospecto theme is lost after the call to setThemeClass and the editor falls back to the default theme. Any suggestions for that?

Thanks and regards,
Sebastian

Hi Sebastian:
You can use editorViewer.editor.getTextView().setOptions({themeClass: "editorTheme"}) any time you want as mentioned in https://wiki.eclipse.org/Orion/How_Tos/Code_Edit#Theming_your_editor.
For example if you ONLY want to change the font size you can trim the css file as below:
.editorTheme.textview {
        font-size: 14px;
}
You then need to dynamically manipulate that css class.

In Orion IDE editor style settings page, by the way, we are using a theme builder to change the css from a complex object and apply that css to the editor. The Code edit build is not exporting that capability but if you really want a complex theme builder, please open a bug describing what you need.
Hope this will help you understanding what happened in Orion IDE.

Thanks,
Libing

Hi,

yeah, I forgot to mention that I like to change the font dynamically and not necessarily on startup. My bad :D
The use case is a „zoom“ control for the editor text, similar to ones found in IDEs like Visual Studio. What happens in the full Orion IDE when the user changes the font size in the settings?

Regards,
Sebastian

Hi,

I’d like to change the font size in the codeEdit widget. Is there a central function to do that properly? Right now I’m working around that by changing the style settings by jQuery:

$('.textview, .textviewTooltip, .contentassist').css('font-size', fontSize + 'px');
$('.textview').css('line-height', (fontSize*1.2) + 'px‘);
$('.contentassist').css('line-height', lineHeight + 'px');
$('.contentassist').css('width', width + 'px');
$('.contentassist').css('height', height + 'px');

and then ‚refreshing‘ the editor using editor.setText(editor.getText()).

However, this results in some ugly artifacts. Especially the second line breaks the zoom ruler, but without it, the lines get smushed in IE11. For the refresh I also tried using editor.getTextView().redraw(), but that causes the line numbers to look ugly.

Thanks and regards,
Sebastian
