By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + +http://www.gnu.org/licenses/gpl-3.0.txt +*/ +/** + * @file ffchartlegend.h + * @brief Contains a necessary class declaration. + * + * @author ComArch S.A. + * @date 2009.08.20 + * @version 1.0 + */ +#ifndef FFCHARTLEGEND_H +#define FFCHARTLEGEND_H +#include +#include +#include +#include +#include + +#include "ffabstractwidget.h" +#include "ffcolorcombobox.h" +#include "ffstringcombobox.h" +#include "ffscrollingcheckbox.h" +#include "fflinecombobox.h" +#include "ffchartlegendcontrolpanel.h" +#include "ffchartseries.h" +#include "ffscrollarea.h" + +static const QString LEGEND_PATH= ":/standard/";///< path to folder with graphics file + +class FFChartLegend; + +/** + * @author ComArch S.A. + * @date 2009.08.20 + * @version 1.0 + * + * @brief A class to store series in legend + */ +class SeriesContainer +{ +private: + friend class FFChartLegend; + + SeriesContainer(FFChartSeries* series, + FFScrollingCheckBox* visibleCheck, + FFLineButton* modifyButton); + ~SeriesContainer(); + + FFChartSeries* series_; ///< pointer to series + FFScrollingCheckBox* visibleCheckBox_; ///< pointer to checkbox responsible for sieries's visiblity + + FFLineButton* controlPanelButton_; ///< pointer to button showing line's syle + +}; + +/** + * @author ComArch S.A. + * @date 2009.08.20 + * @version 1.0 + * + * @brief A class of chart's legend + */ +class FFChartLegend : public FFAbstractWidget +{ + Q_OBJECT + +public: + FFChartLegend(QWidget* parent = 0); + virtual ~FFChartLegend(); + +public slots: + void addSeries(FFChartSeries* series); + void changeSize(); + void deleteSeries(FFChartSeries* ); + +protected: + virtual void resizeEvent(QResizeEvent* event); + virtual void showEvent(QShowEvent* event); + virtual void paintEvent(QPaintEvent *event); + +private: + void init(); + + QWidget* parent; ///< pointer to parent widget + + QString path; ///< path to folder with graphics file + + QGridLayout* legendLayout; ///< legend's layout + + FFScrollArea* legendScrollArea; ///< legend's scroll area + QWidget* legendScrollAreaItem; ///< widget placed on legendscrollarea + QGridLayout* legendScrollAreaLayout; ///< layout of legenScrollAreaItem + + QVector legendSeriesTable; ///< containar of all series on the legend + + SeriesContainer* actualChangingSeries; ///< pointer to actual changing series + + FFChartLegendControlPanel* legendControlPanel; ///< panel for changing line's style + + + QColor backgroundColor; ///< legend background color + qreal backgroundOpacity; ///< legend background opacity + +private slots: + void popUp(); + void chooseChangingSeries(); + void changeVisible(); + void changeSeriesPen(QPen); + +signals: + void updateSeries(); +}; + +#endif // FFCHARTLEGEND_H
