Constructor & Destructor Documentation

◆ Window() [1/3]

open3d::visualization::gui::Window::Window ( const std::string &  title,
int  flags = 0 
)
explicit

Creates a Window that is auto-sized and centered. Window creation is NOT thread-safe. Window must be created on the same thread that calls Application::Run().

◆ Window() [2/3]

open3d::visualization::gui::Window::Window ( const std::string &  title,
int  width,
int  height,
int  flags = 0 
)

Creates a Window that is centered. Window creation is NOT thread-safe. Window must be created on the same thread that calls Application::Run().

◆ Window() [3/3]

open3d::visualization::gui::Window::Window ( const std::string &  title,
int  x,
int  y,
int  width,
int  height,
int  flags = 0 
)

Creates a Window. Window creation is NOT thread-safe. Window must be created on the same thread that calls Application::Run().

◆ ~Window()

open3d::visualization::gui::Window::~Window ( )
virtual

Member Function Documentation

◆ AddChild()

void open3d::visualization::gui::Window::AddChild ( std::shared_ptr< Widget w)

◆ CalcPreferredSize()

Size open3d::visualization::gui::Window::CalcPreferredSize ( )
protectedvirtual

Returns the preferred size of the window. The window is not obligated to honor this size. If all children of the window are layouts, this function does not need to be overridden. This function can only be called after MakeDrawContextCurrent() has been called.

◆ Close()

void open3d::visualization::gui::Window::Close ( )

Closes the window and destroys it. (Same as calling Application::RemoveWindow())

◆ CloseDialog()

void open3d::visualization::gui::Window::CloseDialog ( )

Closes the dialog.

◆ DestroyWindow()

void open3d::visualization::gui::Window::DestroyWindow ( )

This is for internal use in rare circumstances when the destructor will not be called in a timely fashion.

◆ GetChildren()

const std::vector< std::shared_ptr< Widget > > & open3d::visualization::gui::Window::GetChildren ( ) const
protected

◆ GetContentRect()

Rect open3d::visualization::gui::Window::GetContentRect ( ) const

Returns the rectangle that is available to widgets to use; excludes the menubar.

◆ GetOSFrame()

Rect open3d::visualization::gui::Window::GetOSFrame ( ) const

Gets the window's size and position in OS pixels, not actual device pixels.

◆ GetRenderer()

visualization::rendering::Renderer & open3d::visualization::gui::Window::GetRenderer ( ) const

◆ GetScaling()

float open3d::visualization::gui::Window::GetScaling ( ) const

Returns the scaling factor from OS pixels to device pixels.

◆ GetSize()

Size open3d::visualization::gui::Window::GetSize ( ) const

Returns the total interior size of window, in pixels. On Linux this includes the menubar.

◆ GetTheme()

const Theme & open3d::visualization::gui::Window::GetTheme ( ) const

◆ GetTitle()

const char * open3d::visualization::gui::Window::GetTitle ( ) const

◆ GlobalToWindowCoord()

Point open3d::visualization::gui::Window::GlobalToWindowCoord ( int  global_x,
int  global_y 
)

Returns the global point (in OS pixels) in window local coordinates.

◆ IsActiveWindow()

bool open3d::visualization::gui::Window::IsActiveWindow ( ) const

◆ IsVisible()

bool open3d::visualization::gui::Window::IsVisible ( ) const

◆ Layout()

void open3d::visualization::gui::Window::Layout ( const Theme theme)
protectedvirtual

Lays out all the widgets in the window. If all children of the window are layouts, this function does not need to be overriden.

Reimplemented in open3d::visualization::visualizer::O3DVisualizer, and open3d::visualization::GuiVisualizer.

◆ OnDragDropped()

void open3d::visualization::gui::Window::OnDragDropped ( const char *  path)
protectedvirtual

◆ OnMenuItemSelected()

void open3d::visualization::gui::Window::OnMenuItemSelected ( Menu::ItemId  item_id)
protectedvirtual

◆ PostRedraw()

void open3d::visualization::gui::Window::PostRedraw ( )

Sends a draw event to the window through the operating system's event queue.

◆ RaiseToTop()

void open3d::visualization::gui::Window::RaiseToTop ( ) const

◆ SetFocusWidget()

void open3d::visualization::gui::Window::SetFocusWidget ( Widget w)

Sets.

Parameters
was widget with text focus.

◆ SetNeedsLayout()

void open3d::visualization::gui::Window::SetNeedsLayout ( )

Instructs the window to relayout before the next draw.

◆ SetOnMenuItemActivated()

void open3d::visualization::gui::Window::SetOnMenuItemActivated ( Menu::ItemId  item_id,
std::function< void()>  callback 
)

Sets a callback for menu items. If you inherit from Window you can also override OnMenuItemSelected(); however, you should choose one or the other, but don't use both.

◆ SetOnTickEvent()

void open3d::visualization::gui::Window::SetOnTickEvent ( std::function< bool()>  callback)

Sets a callback that will be called on every UI tick (about 10 msec). Callback should return true if a redraw is required (i.e. the UI or a 3D scene has changed), false otherwise.

◆ SetOSFrame()

void open3d::visualization::gui::Window::SetOSFrame ( const Rect r)

Sets the window's size and position in OS pixels, not actual device pixels.

◆ SetSize()

void open3d::visualization::gui::Window::SetSize ( const Size size)

Sets the size of the window in pixels. Includes menubar on Linux.

◆ SetTitle()

void open3d::visualization::gui::Window::SetTitle ( const char *  title)

◆ SetTopmost()

void open3d::visualization::gui::Window::SetTopmost ( bool  topmost)

◆ Show()

void open3d::visualization::gui::Window::Show ( bool  vis = true)

◆ ShowDialog()

void open3d::visualization::gui::Window::ShowDialog ( std::shared_ptr< Dialog dlg)

Shows the dialog. If a dialog is currently being shown it will be closed.

◆ ShowMessageBox()

void open3d::visualization::gui::Window::ShowMessageBox ( const char *  title,
const char *  message 
)

◆ SizeToFit()

void open3d::visualization::gui::Window::SizeToFit ( )

Auto-sizes the window to the results of CalcPreferredSize(), which by default is the size that the layouts of the window want.
