在Qt command prompt下学会使用ui文件

先看下效果：

第一步：

打开QT的Command Prompt，用uic把*.ui变成一个*.h文件。

uic -o ui_dialog.h dialog.ui

这时会根据你设计的ui文件，生成对应的代码：

ui_dialog.h 的代码

QT_BEGIN_NAMESPACE

class Ui_Dialog
{
public:
    QWidget *widget;
    QHBoxLayout *horizontalLayout;
    QVBoxLayout *verticalLayout;
    QLCDNumber *lcdNumber;
    QSlider *horizontalSlider;
    QProgressBar *progressBar;
    QSlider *verticalSlider;

    void setupUi(QDialog *Dialog)
    {
        if (Dialog->objectName().isEmpty())
            Dialog->setObjectName(QString::fromUtf8("Dialog"));
        Dialog->resize(531, 378);
        Dialog->setMaximumSize(QSize(16777215, 55555));
        widget = new QWidget(Dialog);
        widget->setObjectName(QString::fromUtf8("widget"));
        widget->setGeometry(QRect(100, 80, 301, 201));
        horizontalLayout = new QHBoxLayout(widget);
        horizontalLayout->setSpacing(6);
        horizontalLayout->setContentsMargins(11, 11, 11, 11);
        horizontalLayout->setObjectName(QString::fromUtf8("horizontalLayout"));
        horizontalLayout->setContentsMargins(0, 0, 0, 0);
        verticalLayout = new QVBoxLayout();
        verticalLayout->setSpacing(6);
        verticalLayout->setObjectName(QString::fromUtf8("verticalLayout"));
        lcdNumber = new QLCDNumber(widget);
        lcdNumber->setObjectName(QString::fromUtf8("lcdNumber"));
        lcdNumber->setEnabled(true);
        lcdNumber->setMaximumSize(QSize(200, 200));

        verticalLayout->addWidget(lcdNumber);

        horizontalSlider = new QSlider(widget);
        horizontalSlider->setObjectName(QString::fromUtf8("horizontalSlider"));
        horizontalSlider->setMaximum(100);
        horizontalSlider->setOrientation(Qt::Horizontal);

        verticalLayout->addWidget(horizontalSlider);

        progressBar = new QProgressBar(widget);
        progressBar->setObjectName(QString::fromUtf8("progressBar"));
        progressBar->setMaximumSize(QSize(200, 20));
        progressBar->setValue(0);

        verticalLayout->addWidget(progressBar);

        horizontalLayout->addLayout(verticalLayout);

        verticalSlider = new QSlider(widget);
        verticalSlider->setObjectName(QString::fromUtf8("verticalSlider"));
        verticalSlider->setEnabled(true);
        verticalSlider->setMaximumSize(QSize(200, 300));
        verticalSlider->setMaximum(100);
        verticalSlider->setOrientation(Qt::Vertical);

        horizontalLayout->addWidget(verticalSlider);

        retranslateUi(Dialog);
        QObject::connect(verticalSlider, SIGNAL(valueChanged(int)), lcdNumber, SLOT(display(int)));
        QObject::connect(verticalSlider, SIGNAL(valueChanged(int)), horizontalSlider, SLOT(setValue(int)));
        QObject::connect(verticalSlider, SIGNAL(valueChanged(int)), progressBar, SLOT(setValue(int)));
        QObject::connect(horizontalSlider, SIGNAL(valueChanged(int)), verticalSlider, SLOT(setValue(int)));

        QMetaObject::connectSlotsByName(Dialog);
    } // setupUi

    void retranslateUi(QDialog *Dialog)
    {
        Dialog->setWindowTitle(QApplication::translate("Dialog", "Dialog", 0, QApplication::UnicodeUTF8));
    } // retranslateUi

};

namespace Ui {
    class Dialog: public Ui_Dialog {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_DIALOG_H

 

第二步：

现在该使用ui_dialog.h文件，我们在dialog.h文件中使用

#ifndef DIALOG_H
#define DIALOG_H

#include <QDialog>

namespace Ui {
    class Dialog;
}

class Dialog : public QDialog {
    Q_OBJECT
public:
    Dialog(QWidget *parent = 0);
    ~Dialog();

protected:
    void changeEvent(QEvent *e);

private:

 

 //使用ui_dialog.h 中定义的Ui_Dialog
    Ui::Dialog *ui; 

private slots:
    void on_verticalSlider_valueChanged(int value);
};

#endif // DIALOG_H

第三步实现dialog.h中定义的class Dialog 类，即实现

dialog.cpp文件

#include "dialog.h"
#include "ui_dialog.h"

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);
}

Dialog::~Dialog()
{
    delete ui;
}

void Dialog::changeEvent(QEvent *e)
{
    QDialog::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        ui->retranslateUi(this);
        break;
    default:
        break;
    }
}

void Dialog::on_verticalSlider_valueChanged(int value)
{

}

第四步：实现main程序：

#include <QtGui/QApplication>
#include "dialog.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Dialog w;
    w.show();
    return a.exec();
}
第五步：运行命令后再进入debug目录运行程序
