Eclipse: large toolbar icons

Question

Does anybody know how to use large toolbar icons? Edit: How do I do it?

Answer 1

There is no support in Eclipse for large/small icons in the toolbar.
As this bug describes:

The other issue though is really that the GNOME toolbar style, similar to Mac OS X, is for a small number of large icons, while the Eclipse toolbar style is for a large number of quick-access buttons.
This means that the recommendations for, say, icons vs icons+text don't really apply to the Eclipse toolbar.

Update 2016 (5 years later)

Since 2011, you have some workarounds, like this answer referring to davidglevy/eclipse-icon-enlarger, which double the size of the icon in the eclipse main jar.
You have more instructions at PhantomYdn/eclipse-icon-enlarger.

You have the same idea (double the size of icons) implemented as a script (here is an gene1wood/scale_eclipse.sh)

But if the issue is poor (too small) resolution on HiDPI / Retina displays, try also the actual official Microsoft workaround (as illustrated here)

1. regedit:
   HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > SideBySide: create a DWORD PreferExternalManifest set to 1.

2. Beside eclipse.exe, create an eclipse.manifest file with, as content, one similar to this article.

Answer 2

add -Dswt.autoScale=150 in eclipse.ini, is working for my hybrid win10 12.3"

Here is what to do for an easy solution:

1. Go to the start icon of your eclipse or PLCXpressoand
2. Click your right mouse bottom
3. Go to down and click properties
4. Click compartibility
5. Check overwrite high DPI scaling
6. Select system (extended)
7. Click OK at the bottom

Start Eclipse and enjoy

Answer 4

Running Eclipse 2020-09 R (i.e, v4.17) on Linux (openSUSE Tumbleweed with XFCE session) on an HP Spectre x360 with 283 dpi, I found that out of the box the fonts were fine but the icons were unreadably tiny. Also, setting -Dswt.autoscale=300 in the eclipse.ini made the icons look perfect but completely disrupted the layout and functionality of SWT (couldn't click on tabs, many texts were unreadably clipped). So I had to resort to the method of scaling all of the icon files. Here's one way to automate it.

After running eclipse for the first time (since that first run unpacks a lot of icons), go to the top-level eclipse directory (the one in which the eclipse executable resides), and enter xonsh (the python-based shell) in that directory. Then you can execute the following commands (at your own risk), for example by copy-pasting them at the prompt:

pngl = $(find . -name "*.png").strip().split("\n")
for png in pngl: 
     if not ('@2x' in png): 
         print(f"Found icon {png}, moving...") 
         pngo = png.replace('.png','-orig.png') 
         mv @(png) @(pngo) 
         pngbig = png.replace('.png','@2x.png') 
         if pngbig in pngl: 
             print("  ...has enlarged, scaling that by 150") 
             convert @(pngbig) -resize 150% @(png) 
         else: 
             print("  ...no enlargement, scaling orig by 300") 
             convert @(pngo) -resize 300% @(png)

Of course if you wanted a different basic scaling factor, say 250%, you would change the 150% scaling of the double size icon in the pngbig branch to 125% and the 300% scaling of the original-size icons in the other branch to 250%.

Answer 5

Adding this to your eclipse.ini:

-Dswt.enable.autoScale=true
-Dswt.autoScale=150
-Dswt.autoScale.method=nearest

The -Dswt.autoScale=150 will increase your Icons, 150 will say 150%. If it is not enough, increase it.

Answer 6

I solved it on Linux by appending this line to eclipse.ini:

-Dswt.autoScale=200
