解壓qt-everywhere-opensource-src-4.7.0.tgz
到當前目錄。 1.
修改qt-everywhere-opensource-src-4.7.0
/src/gui/embedded
/src/gui/embedded/qkbdtty_qws.h
，其內容如下：
#ifndef qkbdtty_qws_h
#define qkbdtty_qws_h
#include
#ifndef qt_no_qws_keyboard
#ifndef qt_no_qws_kbd_tty
class qwsmykbprivate;
class qwsmykeyboardhandler : publicqwskeyboardhandler
;#endif // qt_no_qws_kbd_tty
#endif // qt_no_qws_keyboard
#endif // qkbdtty_qws_h
2. 修改
qt-everywhere-opensource-src-4.7.0
/src/gui/embedded/
qkbdtty_qws
.cpp
，其內容如下：
#include "qkbdtty_qws.h"
#if !defined(qt_no_qws_keyboard)&& !defined(qt_no_qws_kbd_tty)
#include
#include
#include
#include
#include

#include
class qwsmykbprivate : publicqobject
private q_slots:
void readkeyboarddata();
private:
qwsmykeyboardhandler *m_handler;
qstring terminalname;
int buttonfd;
int kbdidx;
int kbdbufferlen;
unsigned char *kbdbuffer;
qsocketnotifier *notifier;
};qwsmykeyboardhandler::qwsmykeyboardhandler(const qstring&device)
: qwskeyboardhandler(device)
qwsmykeyboardhandler::~qwsmykeyboardhandler()
qwsmykbprivate::qwsmykbprivate(qwsmykeyboardhandler *h, constqstring &device)
: m_handler(h)
printf("open /dev/atao_buttonok!\tbuttonfd=%d\n",buttonfd);
if ( buttonfd >= 0)
kbdbufferlen = 80;
kbdbuffer = new unsigned char[kbdbufferlen];
kbdidx = 0;
}qwsmykbprivate::~qwsmykbprivate()
delete notifier;
notifier = 0;
delete kbdbuffer;;
}voidqwsmykbprivate::readkeyboarddata()
m_handler->processkeyevent( unicode, keycode, 0,true, false );
m_handler->processkeyevent( unicode, keycode, 0,false, false);
//m_handler->processkeyevent( 0, keycode, 0, true,false );
}#include "qkbdtty_qws.moc"
#endif // qt_no_qws_keyboard ||qt_no_qws_kbd_tty
注意，此處，我的鍵盤驅動裝置為/dev/atao_button，使用了4*4矩陣鍵盤，定義如下圖，所要，要先寫好鍵盤驅動啦。 3.
在qt-everywhere-opensource-src-4.7.0
目錄中執行如下
configure命令
./configure -prefix/usr/src/qt470arm.kb.4.2.2 -opensource -confirm-license -release-shared -embedded arm -xplatform qws/linux-arm-g++ -no-qt3support-fast -no-largefile -make tools -make demos -make examples -makedocs -qt-libjpeg -qt-libpng -qt-libtiff -qt-gif -**********
4. make ＆ make install
重新grep "qwsmykeyboardhandler" * -r會得到如下結果表明新增自定義按鍵驅動成功

5. 用qt sdk 開發程式啦。。
4 QT自定義模型
在聊學習之前，想說一下將近乙個星期的時間我都幹了些什麼，為什麼沒有學習，總結起來乙個字 玩，11號朋友遠道而來，說是在家閒得慌，過來找我一起浪，直到昨天才將他送走，既然朋友來了，自然不能怠慢，請他吃飯，帶他閒逛，一起去爬山，還吃了一天的自製火鍋，回想起來這味道有點反胃。獨處的時候適合學習和思考，玩耍...
將矩陣鍵盤加入到QT4中使用
這個資料貌似不多，如果找的到貌似也不全，當然也可以將矩陣鍵盤做成外掛程式到qt中，我實施了一下，還是因為資料不全，自己資質也有限，沒能繼續做下去，能使我做下去的也只有這種要耗費大量精力的簡單重複勞動。下面開始講一下我如何將矩陣鍵盤加入到qt4中使用的。首先就是改qt的原始檔，我改了 src gui ...
