# Manual
This is KolibriOS lua syscalls library. Usually you shouldn't use this library
Better if you read before [KolibriOS syscalls wiki](http://wiki.kolibrios.org/wiki/)
include:
```lua
local syscalls = require("syscalls")
```
## Events
### `SetEventMask(newMask)`
### `CheckEvent()`
check event
### `WaitEvent()`
Endless wait event
### `WaitEventTimeout(timeout)`
Wait timeout 1/100 sec
return event or `nil`
### Events list
```lua
syscalls.Event.<EventName>
```
+ `Redraw`
+ `Button`
+ `Key`
+ `Desktop`
+ `Mouse`
+ `Network`
+ `IPC`
+ `Debug`
## Window
### `CreateWindow(x, y, width, height, workColor, style, borderColor, titleColor)`
Define window
`borderColor` and `borderColor` only for `FixSizes` and `CanChangeSizes` (without skin styles) style.
### `StartRedraw()`
Start window redraw. Just call it before `CreateWindow`
### `EndRedraw()`
End window redraw. Just call it after you done redraw window.
### `ChangeWindow(newX, newY, newWidth, newHeight)`
### `FocusWindow(slot)`
### `UnfocusWindow(slot)`
### `SetWindowTitle(newTitle)`
### `GetSkinHeight()`
return skin height.
### `SetSkin(path)`
return error code
### `GetSkinTitleArea()`
return table:
```lua
{
Left: number,
Right: number,
Top: number,
Bottom: number
}
```
### Style
```lua
syscalls.windowStyle.<Value>
```
+ `FixSizes`
+ `NoDraw` (you must draw window manually)
+ `CanChangeSizes`
+ `WithSkin` (usually use it)
+ `WithSkinFixSizes` (with skin, but window size fixed)
## Graphic
### Text encoding
```lua
syscalls.Encoding.<value>
```

+ `16x32`
+ `18x27` (cp866 only)
+ `24x36` (cp866 only)
+ `24x48`
+ `30x45` (cp866 only)
+ `32x64`

+ `56x112`
+ `64x128`
### `DrawText(text, xPos, yPos, textColor, textScale, textLen, backgroundColor, encoding)`
### `DrawTextFixSize(text, xPos, yPos, textColor, textSize, textLen, backgroundColor, encoding)`
Draw text.
textSize, textLen, backgroundColor, encoding are optional.
### `DrawLine(x1, y1, x2, y2)`
### `DrawRectangle(x, y, widht, height, color)`
### `ReadPoint(x, y)`
return color
## Buttons
### `DefineButton(x, y, widht, height, id, color)`
### `DeleteButton(id)`
### `GetButton()`
return pressed button or `nil`
### `SetButtonStyle(style)`

```lua
syscalls.buttonStyle.<Value>
```
## Keyboard
### `GetKey()`
return:
+ nil if buffer empty
+ if hotkey return second number
+ if key pressed and key input mode is ascii return string(1 char), else return scancode
example:
```lua
local key, hotkey = syscalls.GetKey()
if key then
print("key pressed")
end
if hotkey then
print(hotkey pressed)
end
```
### `SetKeyInputMode(mode)`
by default is `ASCII`
