Detailed Description

A Window. This Window is backed by a native operating system window with a Vulkan surface. The Window should not have any decorations, which are to be drawn by the GUI, because modern design requires drawing of user interface elements in the border.

Member Function Documentation

◆ close_window()

virtual void tt::gui_window::close_window ( )

pure virtual

Ask the operating system to close this window.

◆ fontScale()

float tt::gui_window::fontScale ( ) const

inlinenoexcept

By how much the font needs to be scaled compared to current windowScale.

◆ init()

virtual void tt::gui_window::init ( )

virtual

2 phase constructor.

Must be called directly after the constructor on the same thread, before another thread can send messages to the window.

init() should not take locks on window::mutex.

Reimplemented in tt::gui_window_vulkan.

◆ is_closed()

bool tt::gui_window::is_closed ( )

Check if the window was closed by the operating system.

std::shared_ptr< T > tt::gui_window::make_toolbar_widget ( Args &&... args )

Add a widget to main widget of the window.

Add a widget to the toolbar of the window.

The implementation is in widgets.hpp

The implementation is located here so that widget is a concrete type.

◆ make_widget()

template<typename T , cell_address CellAddress, typename... Args>

std::shared_ptr< T > tt::gui_window::make_widget ( Args &&... args )

Add a widget to main widget of the window.

Add a widget to the main widget of the window.

The implementation is in widgets.hpp

The implementation is located here so that widget is a concrete type.

◆ maximize_window()

virtual void tt::gui_window::maximize_window ( )

pure virtual

Ask the operating system to maximize this window.

Implemented in tt::gui_window_vulkan_macos, and tt::gui_window_vulkan_win32.

◆ minimize_window()

virtual void tt::gui_window::minimize_window ( )

pure virtual

Ask the operating system to minimize this window.

Implemented in tt::gui_window_vulkan_macos, and tt::gui_window_vulkan_win32.

◆ normalize_window()

virtual void tt::gui_window::normalize_window ( )

pure virtual

Ask the operating system to normalize this window.

Implemented in tt::gui_window_vulkan_macos, and tt::gui_window_vulkan_win32.

◆ render()

virtual void tt::gui_window::render ( hires_utc_clock::time_point displayTimePoint )

pure virtual

Update window.

This will update animations and redraw all widgets managed by this window.

Implemented in tt::gui_window_vulkan.

◆ request_redraw()

void tt::gui_window::request_redraw ( aarect rectangle = aarect::infinity() )

inlinenoexcept

Request a rectangle on the window to be redrawn.

◆ set_cursor()

virtual void tt::gui_window::set_cursor ( mouse_cursor cursor )

pure virtual

Set the mouse cursor icon.

Implemented in tt::gui_window_vulkan_macos, and tt::gui_window_vulkan_win32.

◆ set_device()

void tt::gui_window::set_device ( gui_device * device )

Set GPU device to manage this window. Change of the device may be done at runtime.

◆ set_text_on_clipboard()

virtual void tt::gui_window::set_text_on_clipboard ( std::string str )

pure virtualnoexcept

Place a text string on the operating system's clip-board.

void tt::gui_window::update_keyboard_target	(	std::shared_ptr< tt::widget > const &	widget,
		keyboard_focus_group	group,
		keyboard_focus_direction	direction )

noexcept

Change the keyboard focus to the given, previous or next widget.

This function will find the closest widget from the given widget wich belong to the given group; if none is found, or if the original selected widget is found, then no widget will be in focus.

Parameters

widget	The widget to use as the start point for a new widget to select.
group	The group the widget must belong to.
direction	The direction to search in, or current to select the current widget.

◆ update_keyboard_target() [2/2]

void tt::gui_window::update_keyboard_target	(	std::shared_ptr< tt::widget >	widget,
		keyboard_focus_group	group = keyboard_focus_group::normal )

noexcept

Change the keyboard focus to the given widget.

If the group of the widget is incorrect then no widget will be in focus.

Parameters

widget	The new widget to focus, or empty to remove all keyboard focus.
group	The group the widget must belong to.

◆ virtual_screen_size()

virtual f32x4 tt::gui_window::virtual_screen_size ( ) const

pure virtualnoexcept

Get the size of the virtual-screen.

Each window may be on a different virtual screen with different sizes, so retrieve it on a per window basis.

Implemented in tt::gui_window_vulkan_win32.

Field Documentation

◆ active

std::atomic<bool> tt::gui_window::active = false

The window is currently active. Widgets may want to reduce redraws, or change colors.

◆ currentmouse_cursor

mouse_cursor tt::gui_window::currentmouse_cursor = mouse_cursor::None

The current cursor.

Used for optimizing when the operating system cursor is updated. Set to mouse_cursor::None at the start (for the wait icon) and when the operating system is going to display another icon to make sure when it comes back in the application the cursor will be updated correctly.

◆ dpi

float tt::gui_window::dpi = 72.0

Dots-per-inch of the screen where the window is located. If the window is located on multiple screens then one of the screens is used as the source for the DPI value.

◆ extent

f32x4 tt::gui_window::extent

The current window extent as set by the GPU library.

◆ requestLayout

std::atomic<bool> tt::gui_window::requestLayout = true

When set to true the widgets will be layed out.

◆ requestResize

std::atomic<bool> tt::gui_window::requestResize = true

When set to true the window will resize to the size of the contained widget.

◆ resizing

std::atomic<bool> tt::gui_window::resizing = false

The window is currently being resized by the user. We can disable expensive redraws during rendering until this is false again.

◆ size_state

gui_window_size tt::gui_window::size_state = gui_window_size::normal

Current size state of the window.

◆ subpixel_orientation

subpixel_orientation tt::gui_window::subpixel_orientation = subpixel_orientation::BlueRight

Orientation of the RGB subpixels.

◆ widget

std::shared_ptr<window_widget> tt::gui_window::widget

The widget covering the complete window.
