New Icons for Bio7 2.5


Beside many changes for the next release I was able to find the time to update the icons of Bio7 for the next release. The icons are a subset of the FontAwesome icons and some custom icons and were created with Inkscape. They will be made available for free, too.  At the moment the icons are available in two resolutions (100%, 200%) and the larger icons will be used when working with a high DPI monitor (> x dpi). For the rules see:

Here are two screenshots:




Bio7 Toolbar Improved


Finally I was able to find the CSS error in the toolbar layout which resulted in a visible gap when, e.g., the Flow editor was active. Now everything looks much better (see the red arrows!) especially when you install Eclipse plugins which make contributions to the main toolbar.


You can also add this corrections easily to a current Bio7 2.3 installation. Just add the following lines to the default Bio7 CSS (Path: Bio7/plugins/

.MToolBar.Draggable {
  handle-image: url(./dragHandle.png);

.MToolControl.TrimStack {
  handle-image: url(./dragHandle.png);

.MToolControl.Draggable {
  handle-image: url(./dragHandle.png);

And delete the following ‘handle-image’ line in the Perspective Switch attribute:

/*Perspective Switch!*/
#org-eclipse-ui-main-toolbar #PerspectiveSwitcher {
    handle-image: none;

Or just copy over the CSS from the default_win7.css github file.

Solving CentOS 7, Fedora Problems at Startup Wrong Layouts


Here I describe some notable Linux distribution errors which can be corrected with the following startup options (1) and CSS changes (2).

1. Startup Problems

There seems to be problems with CentOS 7  in general. If the application does not start correctly, e.g., the Bio7 window will not be shown then add the following arg (e.g., with a text editor) to the Bio7.ini file in the Bio7 base folder (installation folder).


This arg had to be added like this in the*.ini file (see screenshot – don’t place it wrong else an error will occur!):


After saving the file Bio7 should be started on CentOS 7 (see screenshot below)! Please note that you can also adjust the Java memory there.


Another rare error occuring in Fedora is described here!.
However I tested Bio7 on the latest Fedora release and Bio7 started without any problems.

2. Layout Problems

If the layout of your distribution seems to be distorted (e.g., maximize buttons are to small – could be occuring in the default layout of Fedora and CentOS!) this can be corrected in the Bio7 CSS. The file can be found under:

(win7.css was reused for Linux so please don’t wonder)

The following changed css attributes will correct the height of the toolbars (changed attributes in bold):

.MPartStack {
color: ‘#org-eclipse-ui-workbench-INACTIVE_TAB_TEXT_COLOR’;
 swt-tab-height: 36.0px;

} {
swt-shadow-visible: false;
 swt-tab-height: 36.0px;

/*Important to set height for the view menus!*/
CTabFolder {
swt-corner-radius: 15.0;
swt-tab-height: 36.0px;

Of course you can change other attributes as well, e.g.,  if you want to change a color.
