LabPlot2 is a complete rewrite of LabPlot1 and lacks in this release a lot of features available in the predecessor. On the other hand, the GUI and the usability is more superior as compared to LabPlot1 and there are several new features that were not available in LabPlot1. Brief summary of features and capabilities of LabPlot2 implemented in the first release: * project-based management of data * created objects are organized in a tree and are visualized and accessible in the project explorer * for a better management of objects, additional folders and sub-folders can be created within a project * spreadsheet with very basic functionality is available for manual data entry * "file data source" can be used to import a file and to let LabPlot2 watch for changes in that file * external data from an ascii file can be also directly imported to a spreadsheet for further editing * worksheet is the main object where plots, labels etc. are placed on * several zooming functions for the worksheet * only cartesian plot is implemented in the first release * arbitrary number of freely positionable axes is possible * xy-curve is implemented. As the data source for the x- and y-values columns either from a spreadsheet or from a file data source can be used * several zooming and "movement" functions are available for the plots which help to navigate through data * legend for xy-plots * a lot of properties of the worksheet elements can be edited in a very easy way in the corresponding dock widgets * plots on the worksheet can be put into a horizontal, vertical or grid layouts * export of worksheet (entire worksheet or current seleciton) to pdf, eps, png and svg diff --git a/src/backend/core/AbstractColumn.cpp b/src/backend/core/AbstractColumn.cpp index 57699a729..05e3681de 100644 --- a/src/backend/core/AbstractColumn.cpp +++ b/src/backend/core/AbstractColumn.cpp @@ -1,721 +1,734 @@ /*************************************************************************** File : AbstractColumn.cpp Project : LabPlot Description : Interface definition for data with column logic -------------------------------------------------------------------- Copyright : (C) 2007,2008 Tilman Benkert (thzs@gmx.net) Copyright : (C) 2017 Stefan Gerlach (stefan.gerlach@uni.kn) ***************************************************************************/ /*************************************************************************** * * * This program is free software; you can redistribute it and/or modify * * it under the terms of the GNU General Public License as published by * * the Free Software Foundation; either version 2 of the License, or * * (at your option) any later version. * * * * This program is distributed in the hope that it will be useful, * * but WITHOUT ANY WARRANTY; without even the implied warranty of * * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

To determine the data * type of a class derived from this, use the columnMode() function. * AbstractColumn defines all access functions for all supported data * types but only those corresponding to the return value of columnMode() * will return a meaningful value. Calling functions not belonging to * the data type of the column is safe, but will do nothing (writing * function) or return some default value (reading functions). * * This class also defines all signals which indicate a data change. * Any class whose output values are subject to change over time must emit * the according signals. These signals notify any object working with the * column before and after a change of the column. * In some cases it will be necessary for a class using * the column to connect aboutToBeDestroyed(), to react * to a column's deletion, e.g. a filter's reaction to a * table deletion. * * All writing functions have a "do nothing" standard implementation to * make deriving a read-only class very easy without bothering about the * writing interface. */ /** * \brief Ctor * * \param name the column name (= aspect name) */ AbstractColumn::AbstractColumn(const QString &name, AspectType type) : AbstractAspect(name, type), d( new AbstractColumnPrivate(this) ) { } AbstractColumn::~AbstractColumn() { emit aboutToBeDestroyed(this); delete d; } QStringList AbstractColumn::dateFormats() { static const QStringList dates{"yyyy-MM-dd", "yyyy/MM/dd", "dd/MM/yyyy", "dd/MM/yy", "dd.MM.yyyy", "dd.MM.yy", "MM/yyyy", "dd.MM.", "yyyyMMdd"}; return dates; } QStringList AbstractColumn::timeFormats() { static const QStringList times{"hh", "hh ap", "hh:mm", "hh:mm ap", "hh:mm:ss", "hh:mm:ss.zzz", "hh:mm:ss:zzz", "mm:ss.zzz", "hhmmss"}; return times; } QStringList AbstractColumn::dateTimeFormats() { // any combination of date and times QStringList dateTimes = dateFormats(); for (const auto& t : timeFormats()) dateTimes << t; for (const auto& d : dateFormats()) for (const auto& t : timeFormats()) dateTimes << d + ' ' + t; return dateTimes; } /** * \brief Convenience method for mode-dependent icon */ QIcon AbstractColumn::iconForMode(ColumnMode mode) { switch (mode) { case AbstractColumn::Numeric: case AbstractColumn::Integer: break; case AbstractColumn::Text: return QIcon::fromTheme("draw-text"); case AbstractColumn::DateTime: case AbstractColumn::Month: case AbstractColumn::Day: return QIcon::fromTheme("chronometer"); } return QIcon::fromTheme("x-shape-text"); } /** * \fn bool AbstractColumn::isReadOnly() const * \brief Return whether the object is read-only */ /** * \fn AbstractColumn::ColumnMode AbstractColumn::columnMode() const * \brief Return the column mode * * This function is most used by tables but can also be used * by plots.
