This is a minor patch release of pyjamas 0.4p1, the Python-to-Javascript compiler and Python Web UI Widgets Toolkit. What is Pyjamas for? Pyjamas allows a developer to create U.I applications in python as if the Web Browser was a Desktop Widget Set toolkit platform (like pygtk2, pywxWidgets and pyqt4, only much simpler, and more powerful). No knowledge of javascript programming is required: the python-to-javascript compiler takes care of the conversion between python and javascript, and the U.I widget set takes care of all the browser and AJAX incompatibilities. Why don't I find that exciting? The significance of pyjamas takes a while to sink in. Or you're not a UI developer. Or you've never been asked to write an identical app that works on both the desktop and all major web browsers. If you're a python developer who has followed the history of web application development of the past decade, with much frustration and disappointment, is overwhelmed by Javascript, AJAX and the demands of the "Web 2.00o0ooo0 Revverlushun", then Pyjamas is something that you should consider investigating. Pyjamas 0.4p1 Bug-fixes (and accidental Features) Significant bugs fixed include HorizontalPanel's remove() function, SimplePanel's clear() function, and sprintf with multiple arguments ("%s %d" % ("hello", 2) will now work) Dialog Box now has modal functionality (thanks to jurgen kartnaller). HorizontalSplitPanel has been added, although both the horizontal and vertical panels operate correctly on Mozilla-based browsers, but Safari and IE need volunteers to work on them. Several more examples have also been added, including a spreadsheet-like GridEdit example; a Transparent SVG canvas clock widget (that actually tells the time); an "Information Hierarchy" example that could be used as the basis for an online cooperative spreadsheet editor; Erik Westra's "Showcase" source code which provides and shows the source of the 30 widgets being demo'd; and a few other minor examples.
