Trace Modeler is constantly being improved so be sure to always use the latest release!

v1.6.2 - March 2009

Pressing ENTER when an activation is selected starts edit of the corresponding call label

Further improved the type inferencing algorithm of the 'Build model' feature

Added a few alternative ways to zoom in/out with the mouse, the possibilities are now


Workspace now displays a border around the selected diagram when it has the keyboard focus

On large diagrams, SHIFT-RIGHT-DRAG can be used to scroll 1:1 with the mouse pointer

RIGHT-DRAG scrolls faster, depending on the diagram size

Renamed the shell scripts and executables

for Windows : win_tracemodeler.exe and win_batchexport.exe

for Unix and Linux : and

for Mac OSX : osx_tracemodeler.command and

Some Mac OSX specific changes

Fixed the visual menu glitch, menu are now rendered correctly

Screen menu bar is used instead of a window menu bar (OSX 10.5 only)

Uses the native file dialog for opening and saving trace files

Added a shell script osx_tracemodeler.command that can be run from the Finder

Added lots of OSX-specific keyboard and mouse controls (see manual for a complete list)

Any errors about missing files during the loading of the workspace are now reported in bulk

Fixed : the activations of self calls whose top is off-screen, are now correctly stacked

Changed the standard font for the UI, welcome diagram, default diagram and examples to "Arial"

They no longer rely on the logical "SansSerif" and "Dialog" fonts because they are mapped differently on different platforms

v1.6.1 - March 2009

Added a feature to quickly give feedback about Trace Modeler, available from the toolbar and menu bar

Opens a webpage where you can suggest features or other improvements (no login required)

You can also view and vote for suggestions made by others!

Improved the type inferencing capabilities for the experimental 'Build Model' feature

Added better support for keyboards without a numeric keypad, particularly for zooming in/out. To summarize, the possible ways to zoom in/out are now :

CTRL-MOUSEWHEEL with the mouse
using the corresponding entries in the toolbar and the View Menu
CTRL-PLUS / CTRL-MINUS on the numeric keypad
CTRL-PLUS / CTRL-MINUS on the regular keyboard (if this doesn't work on your keyboard please use CTRL-PAGEUP / CTRL-PAGEDOWN)

Fixed : pressing HOME to reset the view is now working again

v1.6.0 - March 2009

Changed the drag & drop indicator style to make it clearer what will happen when dropped

Indicator for activations now uses an arrow and shows which target will receive the message

Drop indicator color is now blue when the element can be dropped

Drop indicator color is now red when the element cannot be dropped

'Export as image' opens an export dialog where the destination (file/clipboard) can be chosen

Available on the toolbar and the Tools menu

'Export to clipboard' and 'Export to file' were removed from the toolbar and menus

Reorganized the menubar

Removed the Window menu and moved its contents to the other menus

Reordered the entries of the File menu

Added 'Build model [experimental]' to the Tools menu

Added an example for the 'Build Model' functionality

Consists of 4 sequence diagrams depicting 4 representative scenarios for the same domain

Detailed instructions are given in the trace file 'tic-tac-toe readme' in the 'examples' folder of your Trace Modeler installation. This is one of the examples that is automatically opened on first use. If needed, you can quickly open all example diagrams from the Help menu.

Added a new preference setting 'Palettes always visible' (checked by default)

When checked the palettes remain opaque when not in use

When unchecked the palettes become semi-transparent when not in use

When in presentation mode the palette always becomes semi-transparent when not in use

Changes to the 'Preferences' window

'Preferences' window is now modal and has 'Confirm' and 'Cancel' buttons

Removed the blurred background on menubar menus and context menus

The 'Diagram Style' and 'History' windows are now internal windows (again)

v1.5.31 - February 2009

Added three new UML elements : actions, constraints and state invariants

Added support for opening multiple diagrams at once, for every opened diagram an entry is added to the diagram list sidebar

Added a diagram list sidebar

Sidebar can be collapsed/expanded from the menu, toolbar and divider (and from the diagram context menu when using the presentation interface)

Diagrams with unsaved modifications are indicated with a disk icon

Added workspace functionality

When Trace Modeler starts it will automatically reopen all diagrams you were working on when you last exited

many of them related to operand guards and some constructor specific rules

'Optimize target order' can now produce a call-local ordering

Useful for studying huge diagrams

Select a call, activation or return and click 'Optimize target order' and it will layout the targets so that flow around that call can be studied

Added style support, each individual element can now be styled (custom line, fill and text colors).

elements can share common styles and styles can extend each other

style support through files only for now, UI integration is coming soon

Diagram frame can now be added and removed in the same manner as the other elements

removed the 'Diagram frame' diagram style property (no longer necessary)

Added floating comments

the diagram frame will not consider these when calculating its boundary

the comment and its links are drawn with a drop-shadow for easy identification

hold down PAGE UP or PAGE DOWN in text edit mode to see it in action

Some important changes to text edit mode

ENTER will now add a newline (no longer necessary to combine with SHIFT or CTRL)

ESCAPE will now confirm your editing and leave text edit mode (no longer cancels)

if you want to cancel your changes, simply press CTRL-Z during text edit mode or confirm your editing and then undo (using the toolbar, edit menu or CTRL-Z)

available memory report in the export settings window is now updated every 5 seconds

required memory info is now more accurate

reported size in pixels is now correct

Improved tab order

now includes all elements on the diagram and uses their position on the diagram to determine their ideal tab order

The keyboard shortcut for the presentation interface is now F7 (used to be F6)

When using the presentation interface, the diagram context menu now also has an entry to switch back to the regular interface

Added a context menu to the 'Application log' window for easy copying of messages

Target names are now preserved when editing & saving (only relevant if you generate trace files yourself)

Added an arrow that indicates where the diagram is when it is scrolled out of view
