QtGrace v. 1.5 (10/4/2011, Elbert Pol (TeLLie)) Readme/What's new
Compiled now with Qt4.7.3 GA General Notes on Version 0.2.4: This release contains some major and minor bug-fixes. I also included several improvements: - the slider-values are now editable (click on the value, enter a new number and press enter) - a nonlinear fit can be done on one set as usual; if more then one source-set is selected the data of the different sets will silently be combined and the fit will be done on the combined sets (the combined set will not be visible, only the fit-result) - there has been a bug in the filter-dialog, which made the interpolation the only usable option in the point extension (it was possible to select something else, but internally always interpolation was used); I removed the bug and included an option to extend the points with the first and last point before the first point and after the last one - I included a new help-page especially for the extensions in QtGrace in comparison with Grace (I removed the respective entries in this readme) and I included a new example especially for data-filtering and edited some of the existing examples to better match the new window-layout and some of the new features. There is also a new example for the advanced scripting options - I extended the command-window in order to execute all commands with different set-ids and included special command for regression and filtering and some special operations (see the new help-page concerning the QtGrace-extension for any details) - I made the decimal separator selectable (',' or '.') throughout the whole Gui of QtGrace (internally '.' is used all the time) - please note, that this is now a strict setting: if you select ',' as separator you have to enter every number with ',' as separator as well and '.' is ignored. - I extended the support for non-ascii-character by improving the usage of QtFonts (activate it in Preferences->Extra); you also have to set the encoding for saving in the Extra-Preferences (UTF-8 recommended) - this feature is the most complicated in the internal processes and may still contain some bugs, so be watchfull and save early and often; there is obviously a limited compatibility with the original Grace if you use this feature (details: see new help-page) - some minor stuff I do not remember in every detail has been changed / improved (for example I included a bugfix from Grace 5.1.23 concerning the fit-results) (Just an excuse for not updating QtGrace earlier or not having included more new features: The compiler on my Windows7-system stopped working after a regular Windows update. I tried several different things to get it working again, but there still remains an error in some basic library concerning a typedef with a pointer which I do not understand. I spent more time trying unsuccessfully to resolve this problem than I spent actually doing improvements on QtGrace. This made me very frustrated! Furthermore I tried to update QtGrace for the use with Qt5. This did also not work as expected and especially on Windows I could not get it to work properly. Therefore I dropped the support for Qt5 for the moment, although QtGrace should be prepared for it. This whole procedure also cost me valueable time and made me frustrated and therefore I was not as motivated as before. With Qt5.1 it seems to be easier to compile QtGrace - but I have not tested this any further (it works on Mac OS X 10.9 but only using XCode and not QtCreator).) One further request (as always): If you find bugs or missing feature or if you have suggestions for improvements: Let me know immediately! Thank you! Warning: I changed some of the shortcut-keys in contrast to Grace: In order to use Crtl+Z for Undo I used Alt+Z for Zoom. In order to use Crtl+V for paste-operations I used Alt+V for viewport. I hope this will be helpful to someone. Don't hesitate to report bugs/suggestions/wishes.
