Qt&Vtk-030-Theme

摘要

1 官方示例展示

接着搬运，搬运到后面真的不是不想在手撸了，开启Ctrl+C Ctrl+V的节奏，官方示例演示如下

#ifndef THEME_H
#define THEME_H

#include <QWidget>
#include "vtkGraphLayoutView.h"
#include "vtkRandomGraphSource.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkViewTheme.h"
namespace Ui {
class Theme;
}

class Theme : public QWidget
{
    Q_OBJECT

public:
    explicit Theme(QWidget *parent = 0);
    ~Theme();

private:
    Ui::Theme *ui;
    vtkRandomGraphSource* source = nullptr;
    vtkGraphLayoutView* view = nullptr;
    vtkViewTheme* theme = nullptr;
};

#endif // THEME_H

      

2.2 theme.cpp

#include "theme.h"
#include "ui_theme.h"

Theme::Theme(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Theme)
{
    ui->setupUi(this);
    source = vtkRandomGraphSource::New();
    view = vtkGraphLayoutView::New();
    view->SetRepresentationFromInputConnection(source->GetOutputPort());
    theme = vtkViewTheme::CreateMellowTheme();
    view->ApplyViewTheme(theme);
    theme->Delete();
    view->SetRenderWindow(ui->widget->GetRenderWindow());
    view->SetVertexColorArrayName("VertexDegree");
    view->SetColorVertices(true);
    view->SetVertexLabelArrayName("VertexDegree");
    view->SetVertexLabelVisibility(true);
    view->ResetCamera();
    view->Render();
}

Theme::~Theme()
{
    delete ui;
}
