\subsection{Detailed Description}
Low level Evas canvas functions. 

Sub groups will present more high level ones, though.

Most of these functions deal with low level Evas actions, like\+: \begin{DoxyItemize}
\item create/destroy raw canvases, not bound to any displaying engine \item tell a canvas i got focused (in a windowing context, for example) \item tell a canvas a region should not be calculated anymore in rendering \item tell a canvas to render its contents, immediately\end{DoxyItemize}
Most users will be using Evas by means of the {\ttfamily Ecore\+\_\+\+Evas} wrapper, which deals with all the above mentioned issues automatically for them. Thus, you\textquotesingle{}ll be looking at this section only if you\textquotesingle{}re building low level stuff.

The groups within present you functions that deal with the canvas directly, too, and not yet with its {\bfseries objects}. They are the functions you need to use at a minimum to get a working canvas.

Some of the functions in this group are exemplified \hyperlink{Example_Evas_Events}{here}.

Sets the output framespace size of the render engine of the given evas. 

The framespace size is used in the Wayland engines to denote space in the viewport which is occupied by the window frame. This is mainly used in ecore\+\_\+evas to draw borders.

The units used for {\ttfamily w} and {\ttfamily h} depend on the engine used by the evas.

Get the render engine\textquotesingle{}s output viewport coordinates in canvas units. 

Calling this function writes the current canvas output viewport size and location values into the variables pointed to by {\ttfamily x}, {\ttfamily y}, {\ttfamily w} and {\ttfamily h}. On success the variables have the output location and size values written to them in canvas units. Any of {\ttfamily x}, {\ttfamily y}, {\ttfamily w} or {\ttfamily h} that are {\ttfamily null} will not be written to. If {\ttfamily e} is invalid, the results are undefined.

Adds the {\ttfamily keyname} key to the current list of modifier keys. 

Modifiers are keys like shift, alt and ctrl, i.\+e., keys which are meant to be pressed together with others, altering the behavior of the secondly pressed keys somehow. Evas is so that these keys can be user defined.

This call allows custom modifiers to be added to the Evas system at run time. It is then possible to set and unset modifier keys programmatically for other parts of the program to check and act on. Programmers using Evas would check for modifier keys on key event callbacks using \hyperlink{group__Evas__Keys_ga6cc24a5ea4b39b84c7a3e617de3db261}{evas\+\_\+key\+\_\+modifier\+\_\+is\+\_\+set}.

Render the given Evas canvas asynchronously. 

This function only returns {\ttfamily true} when a frame will be rendered. If the previous frame is still rendering, {\ttfamily false} will be returned so the users know not to wait for the updates callback and just return to their main loop.

If a {\ttfamily func} callback is given, a list of updated areas will be generated and the function will be called from the main thread after the rendered frame is flushed to the screen. The resulting list should be freed with \hyperlink{group__Evas__Canvas_ga038d98c7c13a86b6ba4de51f8aba3595}{evas\+\_\+render\+\_\+updates\+\_\+free}.

Add an \char`\"{}obscured region\char`\"{} to an Evas canvas. 

This is the function by which one tells an Evas canvas that a part of it must not be repainted. The region must be rectangular and its coordinates inside the canvas viewport are passed in the call. After this call, the region specified won\textquotesingle{}t participate in any form in Evas\textquotesingle{} calculations and actions during its rendering updates, having its displaying content frozen as it was just after this function took place.

We call it \char`\"{}obscured region\char`\"{} because the most common use case for this rendering (partial) freeze is something else (most probably other canvas) being on top of the specified rectangular region, thus shading it completely from the user\textquotesingle{}s final scene in a display. To avoid unnecessary processing, one should indicate to the obscured canvas not to bother about the non-\/important area.

The majority of users won\textquotesingle{}t have to worry about this function, as they\textquotesingle{}ll be using just one canvas in their applications, with nothing inset or on top of it in any form.

To make this region one that has to be repainted again, call the function \hyperlink{group__Evas__Canvas_ga6bd5caa330850f63f4e9d91271fefc62}{evas\+\_\+obscured\+\_\+clear}.

\begin{DoxyNote}{Note}
This is a very low level function, which most of Evas\textquotesingle{} users wouldn\textquotesingle{}t care about.

This function does not flag the canvas as having its state changed. If you want to re-\/render it afterwards expecting new contents, you have to add \char`\"{}damage\char`\"{} regions yourself (see \hyperlink{group__Evas__Canvas_gab1482931249c640efb25453b54950a16}{evas\+\_\+damage\+\_\+rectangle\+\_\+add}).

Adds the {\ttfamily keyname} key to the current list of lock keys. 

Locks are keys like caps lock, num lock or scroll lock, i.\+e., keys which are meant to be pressed once -- toggling a binary state which is bound to it -- and thus altering the behavior of all subsequently pressed keys somehow, depending on its state. Evas is so that these keys can be defined by the user.

This allows custom locks to be added to the evas system at run time. It is then possible to set and unset lock keys programmatically for other parts of the program to check and act on. Programmers using Evas would check for lock keys on key event callbacks using \hyperlink{group__Evas__Keys_ga08080dfe3ad50c85f4965b9063bfd7de}{evas\+\_\+key\+\_\+lock\+\_\+is\+\_\+set}.

Retrieve the object that currently has focus. 

Evas can have (at most) one of its objects focused at a time.

Most users wouldn\textquotesingle{}t be dealing directly with Evas\textquotesingle{} focused objects. Instead, they would be using a higher level library for that (like a toolkit, as Elementary) to handle focus and who\textquotesingle{}s receiving input for them.

Returns a bitmask with the mouse buttons currently pressed, set to 1. 

Calling this function will return a 32-\/bit integer with the appropriate bits set to 1 that correspond to a mouse button being depressed. This limits Evas to a mouse devices with a maximum of 32 buttons, but that is generally in excess of any host system\textquotesingle{}s pointing device abilities.

The least significant bit corresponds to the first mouse button (button 1) and the most significant bit corresponds to the last mouse button (button 32).

Adds the {\ttfamily keyname} key to the current list of modifier keys. 

Modifiers are keys like shift, alt and ctrl, i.\+e., keys which are meant to be pressed together with others, altering the behavior of the secondly pressed keys somehow. Evas is so that these keys can be user defined.

This call allows custom modifiers to be added to the Evas system at run time. It is then possible to set and unset modifier keys programmatically for other parts of the program to check and act on.

Add an \char`\"{}obscured region\char`\"{} to an Evas canvas. 

This is the function by which one tells an Evas canvas that a part of it must not be repainted. The region must be rectangular and its coordinates inside the canvas viewport are passed in the call. After this call, the region specified won\textquotesingle{}t participate in any form in Evas\textquotesingle{} calculations and actions during its rendering updates, having its displaying content frozen as it was just after this function took place.

We call it \char`\"{}obscured region\char`\"{} because the most common use case for this rendering (partial) freeze is something else (most probably other canvas) being on top of the specified rectangular region, thus shading it completely from the user\textquotesingle{}s final scene in a display. To avoid unnecessary processing, one should indicate to the obscured canvas not to bother about the non-\/important area.

The majority of users won\textquotesingle{}t have to worry about this function, as they\textquotesingle{}ll be using just one canvas in their applications, with nothing inset or on top of it in any form.

To make this region one that has to be repainted again, call the function \hyperlink{group__Evas__Canvas_ga6bd5caa330850f63f4e9d91271fefc62}{evas\+\_\+obscured\+\_\+clear}.

This is a very low level function, which most of Evas\textquotesingle{} users wouldn\textquotesingle{}t care about.

This function does not flag the canvas as having its state changed. If you want to re-\/render it afterwards expecting new contents, you have to add \char`\"{}damage\char`\"{} regions yourself (see \hyperlink{group__Evas__Canvas_gab1482931249c640efb25453b54950a16}{evas\+\_\+damage\+\_\+rectangle\+\_\+add}).

Adds the {\ttfamily keyname} key to the current list of lock keys. 

Locks are keys like caps lock, num lock or scroll lock, i.\+e., keys which are meant to be pressed once -- toggling a binary state which is bound to it -- and thus altering the behavior of all subsequently pressed keys somehow, depending on its state. Evas is so that these keys can be defined by the user.

This allows custom locks to be added to the evas system at run time. It is then possible to set and unset lock keys programmatically for other parts of the program to check and act on. Programmers using Evas would check for lock keys on key event callbacks using \hyperlink{group__Evas__Keys_ga08080dfe3ad50c85f4965b9063bfd7de}{evas\+\_\+key\+\_\+lock\+\_\+is\+\_\+set}.
