Detailed Description

Refer to Zakero_Yetani.h to learn how to include this library.

The intent of this class is to make creating programs that interface directly with Wayland easier. While there are toolkits out there that do this (GTK, Qt, SDL, etc.), they also come with a lot of overhead. This class will abstract much of Wayland and provide a simple event driven interface.

As soon as a connection to the Wayland server has been established, a thread will be created to move all the communications to the background. This means that there is no "main loop" in the Yetani object to hook into. The benefit to this is that Window contents/graphics will not block event handling.

Refer to How To Use It? for a simple example.

Window

Using Yetani to connect to a Wayland Compositor is just the first step. The next step is to create a Window that can display something. This is done using one of the windowCreate() methods. There are 3 sets of methods:

Why three? The traditional pixels for size has many problems in today's display technology. A resolution of 1024x768 may sound consistent in that you know exactly how many pixels will be used on every display. However, 1024x768 may be OK on some displays, it may be too small on 4k laptop screens. And what about the 8k displays?

The easy answer is to find the maximum resolution and use all of it, or just half for a windowed app. Instead of doing that work, why not just use percentages like 1.00x1.00 or 0.50x0.50 that will work on all display resolutions? That is why Yetani has the SizePercent object.

What about millimeters? Using millimeters gives the developer more confidence that size of an area will be physically consistent across devices. To illustrate this consider defining a 300x150 button. This button may be easily clickable on most monitors but may be too small on a 4k display. Defining a button to be 20mm x 10mm, it will be the same physical size on all monitors.

What's wrong with DPI? DPI has become a mess in the computer world and is resolution, not a size.

Thread (not) Safe

The main Wayland event loop runs in a dedicated thread. Because of this, there are race-conditions where execution uses the same data. The most likely thread conflict is the resizing of a surface:

User Thread: Calling one of the window's "size" methods
Wayland Thread: Maximizing/Fullscreen/resizing the window

While the above is mostly protected via mutexs' there is still a chance.

There are other potential problems such as the User Thread deleting a window while the Wayland Thread is resizing the same window. To resolve this issue will require a complete evaluation of data and thread activities.

Or take the easy way out and rewrite Yetani to be single-threaded...

WAYLAND_DISPLAY
Use the value of this environment variable.
"wayland-0"
This is the default display name used by Wayland.

If a connection was successful, then a pointer to a new Yetani instance will be returned. This pointer will need to be deleted by the caller. If there was an error connecting to the Wayland Compositor, nullptr will be returned.

WAYLAND_DISPLAY
Use the value of this environment variable.
"wayland-0"
This is the default display name used by Wayland.

If a connection was successful, then a pointer to a new Yetani instance will be returned. This pointer will need to be deleted by the caller. If there was an error connecting to the Wayland Compositor, nullptr will be returned.

Note: A connection to the Wayland Compositor must be made before any windows are created.

◆ cursorCreate()

std::error_code zakero::Yetani::cursorCreate	(	const std::string &	name,
		const Yetani::CursorConfig &	config
	)

noexcept

A cursor with the given name will be created. The config data will be used to determine how the cursor will be configured.

Cursor Configuration

The CursorConfig::image_data holds the graphic image data for each frame of the cursor. If the cursor is not animated, then only one frame needs to be provided.

Each frame of the cursor (including non-animated cursors, i.e.: a single frame) must have the dimension specified by CursorConfig::size. And the data in each frame must conform to the value of CursorConfig::format. The required amount of data for each frame is: size_in_bytes = size.width * size.height * shmFormatBytesPerPixel(format)

If more than one frame is provided in CursorConfig::image_data, then the amount of time to display each frame must be placed in CursorConfig::time_per_frame.

Once the last frame of the cursor has been displayed, the first frame will be displayed next creating a continuous looping animation.

Every cursor needs to have a spot that is used to determine where the pointer is located called a hotspot. The location of the hotspot is relative to the top-left corner (0x0) and should be assigned to CursorConfig::hotspot_x and CursorConfig::hotspot_y.

If the configuration was valid and the cursor was successfully created, then Yetani::Error_None will be returned. Otherwise, another error will be returned to indicate the encountered problem.

Returns: An error code.

Parameters

name	The name of the cursor
config	The cursor configuration

◆ cursorDestroy()

Yetani::Window * zakero::Yetani::windowCreate	(	const Yetani::SizeMm &	size,
		std::error_code &	error
	)

noexcept

Create a new Window of the specified size. A pointer to the Window will be returned. If there was a problem, a nullptr will returned.

The error parameter will be set to Yetani::Error_None on success or to an appropriate error if there was a problem.

Note: The size of a window must be greater than 0.

Returns: A pointer to the new Window or nullptr on error.

Parameters

size	The window size
error	The error state

◆ windowCreate() [4/9]

Yetani::Window * zakero::Yetani::windowCreate	(	const Yetani::SizePercent &	size,
		const wl_shm_format	format,
		std::error_code &	error
	)

noexcept

Create a new Window of the specified size. A pointer to the Window will be returned. If there was a problem, a nullptr will returned.

The shared memory used by the Window will use the pixel format.

The error parameter will be set to Yetani::Error_None on success or to an appropriate error if there was a problem.

Note: The size of a window must be greater than 0.

Returns: A pointer to the new Window or nullptr on error.

Parameters

size	The window size
format	The pixel format
error	The error state

◆ windowCreate() [5/9]

Yetani::Window * zakero::Yetani::windowCreate	(	const Yetani::SizePercent &	size,
		const wl_shm_format	format = `SHM_FORMAT_DEFAULT`
	)

noexcept

Create a new Window of the specified size. A pointer to the Window will be returned. If there was a problem, a nullptr will returned.

The shared memory used by the Window will use the pixel format.

Note: The size of a window must be greater than 0.

Returns: A pointer to the new Window or nullptr on error.

Parameters

size	The window size
format	The pixel format

◆ windowCreate() [6/9]

Yetani::Window * zakero::Yetani::windowCreate	(	const Yetani::SizePercent &	size,
		std::error_code &	error
	)

noexcept

Create a new Window of the specified size. A pointer to the Window will be returned. If there was a problem, a nullptr will returned.

The error parameter will be set to Yetani::Error_None on success or to an appropriate error if there was a problem.

Note: The size of a window must be greater than 0.

Returns: A pointer to the new Window or nullptr on error.

Parameters

size	The window size
error	The error state

◆ windowCreate() [7/9]

Yetani::Window * zakero::Yetani::windowCreate	(	const Yetani::SizePixel &	size,
		const wl_shm_format	format,
		std::error_code &	error
	)

noexcept

Create a new Window of the specified size. A pointer to the Window will be returned. If there was a problem, a nullptr will returned.

The shared memory used by the Window will use the pixel format.

The error parameter will be set to Yetani::Error_None on success or to an appropriate error if there was a problem.

Note: The size of a window must be greater than 0.

Returns: A pointer to the new Window or nullptr on error.

Parameters

size	The window size
format	The pixel format
error	The error state
