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 ffdpad.h + * @brief Contains a necessary class declaration. + * + * @author ComArch S.A. + * @date 2009.08.11 + * @version 1.0 + */ +#ifndef FFDPAD_H +#define FFDPAD_H + +#include +#include + +#ifndef MAEMO +#include +#endif + +#include "ffdpadbutton.h" +#include "ffviewcache.h" +#include "ffabstractwidget.h" + + +static const QString DPAD_PATH= ":/standard/dpad";///< a part of path to graphics file + +static const int DEFAULT_SIZE = 150; ///< defines a default size of FFDPad +static const int DEFAULT_MIN_SIZE = 100; //< defines a min size of FFDPad + + +/** + * @author ComArch S.A. + * @date 2009.08.11 + * @version 1.0 + * + * @brief A class of 4-way button + */ +#ifdef MAEMO + +class FFDPad : public FFAbstractWidget +{ + Q_OBJECT + +#else + +class QDESIGNER_WIDGET_EXPORT FFDPad : public FFAbstractWidget +{ + Q_OBJECT + Q_PROPERTY(QSize size READ size WRITE setSize) + +#endif +public: + FFDPad(QWidget* parent = 0); + FFDPad(QSize size, QWidget* parent = 0); + virtual ~FFDPad(); + + enum BUTTON_TYPE + { + DPAD_LEFT, //!< signal from left button + DPAD_RIGHT, //!< signal from right button + DPAD_UP, //!< signal from up button + DPAD_DOWN //!< signal from down button + }; + + void setSize(QSize size); + QSize size() const; + + void calculateSize(QSize size); + +signals: + void clicked(int type); + +protected: + virtual void paintEvent(QPaintEvent*); + virtual void resizeEvent(QResizeEvent* event); + +private: + void init(); + + FFViewCache* background; ///< cached dpad's background + + + QGridLayout* layout; ///< a layout of dpad + + FFDPadButton* buttonUp; ///< pointer to the button "Up" + FFDPadButton* buttonDown; ///< pointer to the button "Down" + FFDPadButton* buttonLeft; ///< pointer to the button "Left" + FFDPadButton* buttonRight; ///< pointer to the button "Right" + + QSize size_; ///< size of dpad + QString path; ///< part of path to the graphics file + + int ax; ///< variable used to center dpad's buttons on X axis + int ay; ///< variable used to center dpad's buttons on Y axis +}; + +#endif // FFDPAD_H
