overlay
- it is a window what try to stay over any other windows( even fullscreen games ) and show content of some source
.
source
- can be other window like chat or cpu monitor.
It should be build as nodejs module.
There is cmake project file in repository what can be used to make node module.
To setup env and make a build use command
yarn install
Module file will be in 'build\Release'
And to make build again after source code changed
cmake -G "Visual Studio 16 2019" -A x64 ../
cmake --build . --target install --config Release
- node
- yarn
- msbuild (vs studio make tools )
Examples to show api usage for simple usecases.
yarn electron examples\example_with_offscreen.js
yarn electron examples\example_interactivity_console.js
yarn electron examples\example_interactivity_window.js
Each overlay has ID by which it can be adressed in api.
Thread what control overlays have to be started and stoped explicitly by module user
start()
stop()
For now overlays can be shown and hidden all together
show()
hide()
To get basic info about overlays
getCount()
getIds()
it return list of overlay ids.getInfo(overlay_id)
To create, setup and remove overlay
addHWND(hwnd)
return overlay idsetPosition(overlay_id, x, y, width, height)
setTransparency(overlay_id, transparency)
from 0 to 255 like in SetLayeredWindowAttributesreload(overlay_id)
send web view a command to reload current pageremove(overlay_id)
paintOverlay(overlay_id, width, height, bitmap)
For interective mode set callbacks and switch on/off. See examples\example_with_hwnd_node.js.
setMouseCallback(callback)
setKeyabordCallback(callback)
switchInteractiveMode()
