Minor UI Changes
Overview
There have been a couple of minor changes in the user interface of PTC Arbortext Layout Developer 12.0.0.0 which are intended to make life easier for template developers.
JavaScript Tags Font and Syntax Highlighting
The default font of JavaScript tags (both .js and .jf) has been changed to use a monospaced font to make them easier to read. Syntax highlighting has also been applied to help readability.
Blue and Yellow Bar Colours
The colours specified for both the left (blue) bar and the edit (yellow) bar have been tweaked to make them fit with the new colour scheme.
Frame Selection
It has always been frustrating that a layer must be active in order to select a frame on it. From 12.0.0.0 of Layout Developer, users can use Ctrl and the left mouse button to select a frame on any layer.
Edit (Yellow) Bar
A couple of changes have been made to support the edit bar too. Firstly, a method has been introduced to open a stream in the edit bar (fStream.sendToEditBar), and secondly a template property has been provided to test which stream is open in the edit bar (fTemplate.editBarStream). The fStream.sendToEditBar() method can take start and end character position arguments.
Draw Level Changes
Two new draw level changes have been made. fDrawLevel.currentLayer tells Layout Developer to show outlines of frames which exist on the currently selected layer. fDrawLevel.blockGuideLevel can take a number value which will indicate which block nesting level to draw block guides for. This property allows users to see block guides for specific nesting levels, and thereby find how their block nesting is working.
