DockWidget参数窗口的创建

Qt QMainWindow上添加QDockWidget窗口

<一>、建立一个标准的参数Dialog ：StdDialog(QDockWidget)

（窗口(QWidget) -> LeftParamDlg/ RightParamDlg(QFrame)->StdDialog(QDockWidget)）

窗口(QWidget) ：designer设计

LeftParamDlg/ RightParamDlg(QFrame)：刚才的窗口能够显示

StdDialog(QDockWidget)：可以用来调度不同的LeftParamDlg/ LeftParamDlg。

1、设计窗口，创建一个QWidget窗口

2、显示每个窗口的类，继承QFrame

eg：//LeftParamDlg.h

#ifndef LEFTPARAMDLG_H

#define LEFTPARAMDLG_H

#include "GeneratedFiles/ui_parameterleft.h"

#include <QFrame>

#include <QWidget>

 

class LeftParamDlg : public QFrame

{

Q_OBJECT

public:

LeftParamDlg(QWidget *parent = 0);

~LeftParamDlg();

private:

Ui::LeftParamWidget *ui;

};

#endif

//LeftParamDlg.cpp

#include "leftparamdlg.h"

LeftParamDlg::LeftParamDlg(QWidget *parent) 

:QFrame(parent)

{

ui = new Ui::LeftParamWidget;

LeftParamDlg::ui->setupUi(this);

}

LeftParamDlg::~LeftParamDlg()

{

delete ui;

ui = NULL;

}

同理，如果有RightPramDlg也这样写一个类来进行显示

3、标准对话框调用：StdDialog(QDockWidget)，继承自QDockWidget

eg：//StdParamDialog.h

#ifndef CPARAMETERDIALOG_H

#define CPARAMETERDIALOG_H

#include <QDockWidget>

class QFrame;

class LeftParamDlg;

class RightParamDlg;

class CParameterDialog : public QDockWidget

{

Q_OBJECT

public:

CParameterDialog(QWidget *parent = 0);

~CParameterDialog();

bool showLeftPrmDlg();

bool showRightPrmDlg();

private:

void init();

void createFrame();

void loadLeftPrmDlg();

void loadRightPrmDlg();

private:

QFrame *mainFrame_;

LeftParamDlg *leftPrmDlg_;

RightParamDlg *rightPrmDlg_;

};

#endif

//StdParamDialog.cpp

#include "parameterdialog.h"

#include "leftparamdlg.h"

#include "rightparamdlg.h"

#include <QFrame>

#include <QGridLayout>

CParameterDialog::CParameterDialog(QWidget *parent) 

: QDockWidget(parent)

{

init();

}

CParameterDialog::~CParameterDialog()

{

if (leftPrmDlg_)

delete leftPrmDlg_;

leftPrmDlg_ = NULL;

if (rightPrmDlg_)

delete rightPrmDlg_;

rightPrmDlg_ = NULL;

 

if (mainFrame_)

delete mainFrame_;

mainFrame_ = NULL;

}

bool CParameterDialog::showLeftPrmDlg()

{

createFrame();

loadLeftPrmDlg();

return true;

}

bool CParameterDialog::showRightPrmDlg()

{

createFrame();

loadRightPrmDlg();

return true;

}

void CParameterDialog::loadLeftPrmDlg()

{

//Grid和VBox都可以

//assert(mainFrame_);

mainFrame_->hide();

//QGridLayout *gridLayout = new QGridLayout(mainFrame_);

//mainFrame_->setLayout(gridLayout);

//setWindowTitle("Left Parameters");

 

//leftPrmDlg_ = new LeftParamDlg(this);

 

//gridLayout->setRowMinimumHeight(1,400);

//gridLayout->setColumnMinimumWidth(0,200);

 

//gridLayout->addWidget(leftPrmDlg_,1,0,7,10);

QVBoxLayout *gridLayout = new QVBoxLayout(mainFrame_);

mainFrame_->setLayout(gridLayout);

setWindowTitle("Left Parameters");

 

 

leftPrmDlg_ = new LeftParamDlg(this);

 

gridLayout->addWidget(leftPrmDlg_);

 

mainFrame_->showNormal();

mainFrame_->adjustSize();

//set the minimum size so it will shrink down to the right size

setMinimumSize(mainFrame_->sizeHint());

 

showNormal();

adjustSize();

}

 

 

void CParameterDialog::loadRightPrmDlg()

{

//assert(mainFrame_);

mainFrame_->hide();

QGridLayout *gridLayout = new QGridLayout(mainFrame_);

mainFrame_->setLayout(gridLayout);

setWindowTitle("Right Parameters");

 

 

rightPrmDlg_ = new RightParamDlg(this);

//rightPrmDlg_->setFrameConent();

gridLayout->setRowMinimumHeight(2,100);

gridLayout->setColumnMinimumWidth(1,200);

 

gridLayout->addWidget(rightPrmDlg_,1,0,7,10);

 

mainFrame_->showNormal();

mainFrame_->adjustSize();

//set the minimum size so it will shrink down to the right size

setMinimumSize(mainFrame_->sizeHint());

 

showNormal();

adjustSize();

}

void CParameterDialog::init()

{

mainFrame_ = NULL;

leftPrmDlg_ = NULL;

rightPrmDlg_ = NULL;

}

void CParameterDialog::createFrame()

{

if (mainFrame_)

delete mainFrame_;

QFrame *newFrame = new QFrame;

setWidget(newFrame);

setSizePolicy(QSizePolicy::Minimum,QSizePolicy::Minimum);

mainFrame_ = newFrame;

}

 

 

<二>、action按钮与Dialog关联

在QMainWindow头文件中，声明不同的STDParaDialog类名，调用不同方法显示窗口

QMainWindow的头文件中

private:

CParameterDialog *leftParamDlg_;

CParameterDialog *rightParamDlg_;

private slots:

void showLeftParamDlg();

void showRightParamDlg();

QMainWindow的cpp文件中

leftParamDlg_ = NULL;

rightParamDlg_ = NULL;

connect(ui.actionParam_Left, SIGNAL(triggered()), this, SLOT(showLeftParamDlg()));

connect(ui.actionParam_Right, SIGNAL(triggered()), this, SLOT(showRightParamDlg()));

void CMainWindow::showLeftParamDlg()

{

if (leftParamDlg_ != NULL)

{

leftParamDlg_->close();

delete leftParamDlg_;

leftParamDlg_ = NULL;

}

leftParamDlg_ = new CParameterDialog(this);

leftParamDlg_->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);

addDockWidget(Qt::LeftDockWidgetArea, leftParamDlg_, Qt::Horizontal);

leftParamDlg_->setFloating(false);

leftParamDlg_->hide();

leftParamDlg_->showLeftPrmDlg();

}

 

 

void CMainWindow::showRightParamDlg()

{

if (rightParamDlg_ != NULL)

{

rightParamDlg_->close();

delete rightParamDlg_;

rightParamDlg_ = NULL;

}

rightParamDlg_ = new CParameterDialog(this);

rightParamDlg_->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);

addDockWidget(Qt::LeftDockWidgetArea, rightParamDlg_, Qt::Horizontal);

rightParamDlg_->setFloating(false);

rightParamDlg_->hide();

rightParamDlg_->showRightPrmDlg();

}
