vs+qt-vs-addin-1.1.11-opensource开发环境下：如何添加qdialog，并可以用设计师设计

我们现在的开发环境是VS2010+QT插件的方式，这个时候我想在某个工程里面添加一个dialog对话框，分三步走：

第一步：用QT Designer 新建一个.ui文件，命名为geostralayerNameChoice.ui，然后完成编辑。



第一：新增加一个dialog类，继承自 QDialog，比如class CGeoStraLayerNameChoiceDialog :public QDialog。

在类的头文件中添加如下代码：

/**

* @file GeoStraLayerNameChoiceDialog.h

* @brief

* @date 2015-5-22

* @author: hudongfang

*/

#ifndef PAI_FRAME_CGEOSTRALAYERNAMECHOICEDIALOG_H

#define PAI_FRAME_CGEOSTRALAYERNAMECHOICEDIALOG_H

#pragma warning( push ,0 )

#include <QDialog>

#include "OSGFramework.h"

#include "GeologicalStratificationTree.h"

#include "GeologicalStratificatonObject.h"

#include "DialogFactory.h"

#pragma warning( pop )

namespace Ui

{

class GeoStraLayerNameChoiceDialog;

}

using namespace pai::datamodel;

BEGIN_OSGGRAPHICS_NAMESPACE

class CGeoStraLayerNameChoiceDialog :public QDialog,public CDialogFactory

{

Q_OBJECT

public:

CGeoStraLayerNameChoiceDialog(QWidget *parent = 0, Qt::WFlags flags = 0);

~CGeoStraLayerNameChoiceDialog(void);

private slots:

void slotOK();

void slotCancel();

//void slotEdit();

virtual QString GetGuid();

private:

Ui::GeoStraLayerNameChoiceDialog* m_pUI;

//层位级别树

CGeologicalStratificationTree* m_pDataTree_GeoStra;

};

END_OSGGRAPHICS_NAMESPACE

//using namespace pai::graphics;

#endif

在源文件的构造函数中添加如下代码：

#include <QHBoxLayout>

#include "GeoStraLayerNameChoiceDialog.h"

#include "ui_GeoStraLayerNameChoice.h"

#include "GeologicalStratificationRoot.h"

#include "OSGDataModel.h"

#include "GeologicalStratificationDialog.h"

#include "ObjProject.h"

#include "BaseObject.h"

using namespace pai::datamodel;

BEGIN_OSGGRAPHICS_NAMESPACE

CGeoStraLayerNameChoiceDialog::CGeoStraLayerNameChoiceDialog(QWidget *parent, Qt::WFlags flags)

:QDialog(parent,flags),

m_pDataTree_GeoStra(NULL)

{

m_pUI = new Ui::GeoStraLayerNameChoiceDialog();

m_pUI->setupUi(this);

//地质分层命名树

m_pDataTree_GeoStra = new CGeologicalStratificationTree(this);

m_pDataTree_GeoStra->InitTreeType(eTree_GeologicalStratification);

//SetGeoStraTree(m_pDataTree_Geological);

QHBoxLayout * hLayout = new QHBoxLayout();

hLayout->addWidget(m_pDataTree_GeoStra);

hLayout->setContentsMargins(10,10,10,10);

m_pUI->groupBox_layerName->setLayout(hLayout);

if( GetProject() )

{

m_pDataTree_GeoStra->SetRootObject(GetProject()->GetGeologicalStratificationRoot(true));

PaiObject *pObject = GetProject()->GetGeologicalStratificationRoot(true);

QList<PaiObject *> listChild;

pObject->GetChildren(listChild);

PaiObject::m_eventAgent.OnObjectAddChildren( pObject,listChild);

}

QObject::connect(m_pUI->pushButton_OK, SIGNAL(clicked()), this, SLOT(slotOK()) );

QObject::connect(m_pUI->pushButton_CANCEL, SIGNAL(clicked()), this, SLOT(slotCancel()) );

//QObject::connect(m_pUI->pushButton_Edit, SIGNAL(clicked()), this, SLOT(slotEdit()) );

}

CGeoStraLayerNameChoiceDialog::~CGeoStraLayerNameChoiceDialog(void)

{

delete m_pUI;

m_pUI = NULL;

delete m_pDataTree_GeoStra;

m_pDataTree_GeoStra = NULL;

}

void CGeoStraLayerNameChoiceDialog::slotOK()

{

QTreeWidgetItem * pTreeItem = m_pDataTree_GeoStra->currentItem();

QString strName = pTreeItem->text(0);

this->setWindowTitle(strName);

QDialog::accept();//注意此处如何调用基类的确定代码

}

void CGeoStraLayerNameChoiceDialog::slotCancel()

{

QDialog::reject();//注意此处如何调用积累的取消代码（关闭对话框）

}

附：

CSelectDlg dlg;

int res = dlg.exec();

if (res == QDialog::Accepted) isOilLayer = true;

if (res == QDialog::Rejected) isOilLayer = false;

//注意 QDialog::accept()、QDialog::reject()、 QDialog::Accepted、 QDialog::Rejected
