CloudCompare简单二次开发(上):https://blog.csdn.net/NEXUS666/article/details/111330786
一、moc_ColorChangeTool.cpp文件生成
(1)新建一个空类ColorChangeTool,为了使得功能界面能够停靠在GLWindow上,需要令ColorChangeTool继承自ccOverlayDialog类。而ccOverlayDialog类又继承自QDialog,QDialog继承自QWidget,QWidget继承自Qt祖宗类QObject,因此ColorChangeTool是一个支持Q_OBJECT宏的QObject对象!为了使得ColorChangeTool支持“信号-槽”机制,需要加入“Q_OBJECT宏”!
(2)右键,进入ColorChangeTool.h的属性页,将“配置属性>>>常规>>>项类型”从“C\C++标头”更改为“自定义生成工具”,点击应用。
(3)自定义生成工具配置
命令行:(注意命令行里是有空格的!)
moc.exe ColorChangeTool.h文件的全路径 -o moc_ColorChangeTool.cpp文件生成路径的全路径
说明:
Performing Custom Build Tools
输出:
moc_ColorChangeTool.cpp
附加依赖项:
moc.exe
ColorChangeTool.h
(4)利用ColorChangeTool.h文件编译生成moc_ColorChangeTool.cpp文件,并务必将moc_ColorChangeTool.cpp文件添加现有项至工程中!如果这里moc文件编译失败,请检查文件名、内容格式、路径等有无错误!
二、废话少说,下面直接挒代码
主窗体菜单栏二次开发功能按钮槽函数doActionColorChange():
void MainWindow::doActionColorChange()
{
//判断DB-Tree内是否选中对象
if (!haveOneSelection())
{
ccConsole::Error(QStringLiteral("请在 DB Tree 内选择点云实体对象!"));
return;
}
//获取当前DB-Tree中选择的实体对象
ccHObject* ent = m_selectedEntities[0];
//判断是否为点云对象(这里也可能是矢量栅格对象)
if (!ent->isKindOf(CC_TYPES::POINT_CLOUD))
{
ccConsole::Error(QStringLiteral("选择的对象不是点云类型!"));
return;
}
//将实体对象ent转换成ccGenericPointCloud对象
ccGenericPointCloud* gCloud = ccHObjectCaster::ToGenericPointCloud(ent);
//ccGenericPointCloud是抽象类,不能被实例化,所以向下转换成子类对象ccPointCloud,我们可以通过ccPointCloud来操作点云
ccPointCloud* pCloud = static_cast<ccPointCloud*>(gCloud);
//Qt MDI框架
QMdiSubWindow* qWin = m_mdiArea->activeSubWindow();
if (!qWin)
return;
if (!m_colorDlg)
{
//自定义对象m_colorDlg传入点云pCloud
m_colorDlg = new ColorChangeTool(qWin, pCloud);
//连接信号槽:使得后台可以实时获取用户在DB-Tree内所选中的点云
connect(m_ccRoot, &ccDBRoot::selectionChanged, m_colorDlg, &ColorChangeTool::GetSelectedCloud);
//当DB-Tree为空时,清空点云
connect(m_ccRoot, &ccDBRoot::dbIsEmpty, m_colorDlg, &ColorChangeTool::onClear);
//使得m_colorDlg能够停靠在点云显示窗口的右上角
registerOverlayDialog(m_colorDlg, Qt::TopRightCorner);
}
//显示m_colorDlg
m_colorDlg->start();
updateOverlayDialogsPlacement();
