ui文件實際上是標(biāo)準(zhǔn)的xml格式的文本文件，它需要通過UIC工具轉(zhuǎn)換為項目中可用的文件，這是頭文件中可用的真正C++代碼，那么Qt之ui在程序中的使用-多繼承法介紹大家清楚嗎？別著急，武林技術(shù)頻道為大家細(xì)細(xì)道來。
#ifndef THIRDDIALOG_H
#define THIRDDIALOG_H
#include <QtGui>
#include "ui_third.h"
class thirdDialog:public QDialog,private Ui::Third
{
Q_OBJECT
public:
thirdDialog(QWidget *parent=0);
~thirdDialog();
};
#endif
thirdDialog.cpp
#include "thirdDialog.h"
thirdDialog::thirdDialog(QWidget *parent)
{
setupUi(this);
}
thirdDialog::~thirdDialog()

tabWidget->resize(300,300);
connect(firstUi.btnClose,SIGNAL(clicked()),this,SLOT(close()));
connect(secondUi.btnChild,SIGNAL(clicked()),this,SLOT(on_btnChild_clicked()));

void MainDialog::on_btnChild_clicked()

dlg->exec();
}
以上就是Qt之ui在程序中的使用-多繼承法介紹，不過一般都會先測試能否正常使用，不過大家還是可以放心的，更多的專業(yè)知識請關(guān)注武林技術(shù)頻道！
