I have a GTK3 application with buttons which contain a transparent image over a coloured background, when I compile it on a Linux Mint machine I get a perfectly normal "flat" image, but when I compile it on a Raspberry Pi (in Raspbian OS) I get buttons that have a weird white highlight effect on the image.
All I can guess is that the default GTK theme on Raspbian includes some sort of shadow effect that is being applied to the button images but I don't know which one & hence how to override it.
I've dug through the GTK theme/CSS docs but can't find anything obvious that would be applying this effect to an image. I've also poked about in the system(s) for GTK themes/gtk CSS files but there's loads of them, so I'm hoping someone can help me narrow this down to a particular tag/style I can apply to my buttons/widgets/window to make it look right all the time.
Image 1: normal "flat" image:
Image 2: weird fringe highlight / shadow effect on image:
Well after some mucking about with GTK_DEBUG=interactive ./my_app I found it was caused by this setting in the default Raspbian theme:
*{-gtk-icon-shadow:none;}
That one-liner in my application's overall window CSS has fixed it.
As you can see in the images I provided, the upper left menu options text is huge. I don't know why this is, I think I updated Qt and then suddenly it looked like this the next time I ran it. I have tried to search for solutions for how to get regular size back but I find pretty much only things related to code font size. Does anyone know how I can get back the original, much smaller and easy-on-the eyes text size?
This is a bug in QtCreator 9.0.0. It will be fixed in version 9.0.1. which will hopefully come out soon. If you do not want to wait, you can download and install some snapshot of QtCreator 9.0.1. here https://download.qt.io/snapshots/qtcreator/9.0/9.0.1/ See also https://bugreports.qt.io/browse/QTCREATORBUG-28499 for some other workarounds.
When I try to browser my white icons with transparent backgrounds, I get this:
Finder adds it's own white backgrounds behind my icons. It makes my design work impossible. Similair threads have been made in the past, where the chosen solution was to create and automator script that looks like this:
However, the "add thumbnail icons to image files" option is missing in Mac OS Monterey. Anyone has a fix, a workaround? This is quite a widespread problem as it makes working with white icons on Mac simply impossible.
Many many thanks, any info would be appreciated!
I can't for the life of me figure out why the same font that I build using gulp-iconfont renders so wildly different on Windows vs. basically all other OSes, including mobile OSes. I've tested practically all of them through Browserstack, and consistently all browser running on Windows render the font with a massive amount of space above/below each icon while all other platforms render as expected.
I highlighted the elements using the inspector for the following screenshots:
Windows:
macOS:
I think I have narrowed it down to be the font rendering, as when I change the font-family in the css, the spacing around the characters evaporates. I have messed around with the gulp-iconfont options (fontHeight is set to 1024 and font is being normalized) without success.
Is my only option to let go of compiling my own iconfont and just using svg's, or does anyone know what I might be doing wrong? I feel the stench of defeat upon me so any faint scent of hope would make me simmer with joy.
This is not a question about changing the font size in graphs produced using RStudio. I already know how to do that.
I use RStudio under Linux on a MacBook Pro with a 'retina' display. I use KDE as my window manager. I can (and do) enlarge the default font size in the user interface of other programs in KDE. I increase the font size for the user interface in Firefox and Thunderbird using program specific tools.
How do I increase the font size in the user interface - not the console, which is easy [Options -> Appearance -> font size], but, for example, the help text, the keyboard shortcuts list, and so on. At the moment I find these very hard to read. I've fiddled with everything I can fiddle with, but had no joy.
All help gratefully appreciated!
As some people pointed out, by clicking the ctrl & + together, you can enlarge the font size for everything including for the console & code script. (You will have to do it with a help page pop up as suggested by user3619015.) Then go to the global option and resize the fonts. That changes the font size for everything except the help page. So you will have larger fonts for the help page but everything else in your normal preferred font size.
On a Mac you can do it by going to: view -> actual size or just with the key combo: cmd+= (not cmd++) to zoom in (bigger), cmd+- or zoom out or cmd+0 (zero) to go back to the actual size.
Rstudio doesn't support changing fonts yet, at least for Linux server. However, one can change fonts in browser for a specific page. At least in chrome, you can customize fonts using an extension called font changer. I think it is packed with all GNU free fonts for legal issues. But, since you have the font files in the OS, like consolas, you can practically change to whatever font and size you like. Just play with it.
I had the same problem here using a MacBook Pro although not with KDE, but you could try on the menu of RStudio:
View -> Actual size
After a couple of days struggling to read the help, this worked: increased the size of letters in all windows of RStudio.
Help, Files, Packages can be opened in a new browser window where zoom in and out options are possible. Even a selected specific package can be opened in a new window for clear view
While this is quite an old question, you can now also change your font size under Linux like that:
Tools -> Global Options... -> Appearance -> Editor font size
Here's how I got around the problem:
Simply copy and paste into your word processor or text editor. Text will be pasted in the default text.
I'm using Windows 8.1, Office 2013 and R 64 bit. Not optimal but it works.
