I had searched around to find examples but none I could find. in QML doc, onRotationFinished would provide the PinchEvent but with its property that we can use them. but I can seem to find how to get the PinchObject.
Do you have to do something like?
gesture.onRotationFinished: function(event){
console.log(event.angle, event.rotation)
}

I can't find anywhere on the internet. I made some custom key bindings using stuff like:
editor = #getModel()
bufferRow = editor.bufferPositionForScreenPosition(editor.getCursorScreenPosition()).row
if editor.isFoldedAtBufferRow(bufferRow)
editor.unfoldBufferRow(bufferRow)
else
editor.foldBufferRow(bufferRow)
and
atom.workspace.getActiveTextEditor()?.selectAll()
atom.workspace.getActiveTextEditor()?.pasteText()
atom.workspace.getActiveTextEditor()?.save()
But I had to search so much. No list of all functions to use?
PS: Best thing close to it for me was: https://gist.github.com/philipmadeley/1fb35efdf5ab639c12c6
Atom has an abundance of documentation over at https://atom.io/docs/
More specifically, this would be what you were looking for:

I am trying to create me a PX/REM converter in LESS CSS but I am facing a problem.
The following lines do not want to compile, the problem comes from #{propertyValue}:.
.rem(#propertyValue; #sizeValue) {
#remValue: #sizeValue / unit(#base-font-size);
#{propertyValue}: ~"#{remValue}rem";
}
But yet I think the syntax is good... at last I thought! Can you help me?
Thank you!
Are you using at least LESS 1.6? Variables as property names were added in 1.6. Prior to 1.6 there are some solutions but none are pretty.
Your snippet works in this LESS previewer which is running 1.6.0: less2css
Like this
#ShuttleGrey: #606369;
I need same output color value from more variables [I am looking for a single line solution]
#themeOne:, #themeTwo:, #themeThree: #ShuttleGrey;
I know my code is an error , Does anyone know to fix this situation ?
Thanks
Assuming that you want the same properties to apply in many places you can do something like this
.aProperty{
color:#606369
}
Then you can do something like this to add the same properties to other elements
.anotherProperty{
background:#000; //just like that
.aProperty;
}
This way .anotherProperty will inherit the properties of aProperty.
This way you can even add other properties and use them at many places.
.aProperty{
color:#606369
}
Then you can do something like this to add the same properties to other elements
.anotherProperty{
background:#000; //just like that
.aProperty;
}
Since no answer is accepted I am trying my luck:)
I'm starting with paper.js. I like the fact that it introduces the possibility to have a script with a text/paperscript mime type, which runs in its on scope. However, scripts can become large pretty soon, so I want to be able to divide it in multiple scripts for readability. I thought I could just add more than one script tag and have them all run in the same scope, but apparently this isn't the case.
Both scripts are loaded and do run, but the second script doesn't seem to be in the paper scope.
I've set up an example here: http://barbata.nl/SO/Maps/ This example has some code, but I'll point out the important bits.
It contains two paperscripts:
Maps.js is the main script, which rasterizes the image and allows moving it around. You can ignore the code in this script, for it works fine so far.
Zoom.js is the script in which I wanted to isolate zooming functionality. It uses jq.mobi to capture the scroll wheel of the mouse, since Paper.js doesn't seem to have that event. It then translates that to a call to onMouseScroll, in a similar way Paper does it.
So far so good. The actual problem arises with the zoomIn and zoomOut functions in zoom.js.
It works if I explicity use the paper object to reference the view I want to zoom:
function zoomIn()
{
if (paper.view.zoom < 2)
{
paper.view.zoom = paper.view.zoom * 2;
}
}
But it fails when I remove paper and just reference the view:
function zoomIn()
{
if (view.zoom < 2)
{
view.zoom = view.zoom * 2;
}
}
This surprises me, as I expected the script to be a Paperscript, running in the Paperscope. It works fine if I put this code in Maps.js, so it seems that although zoom.js is loaded by Paper.js (the developer tools in the browser confirm this), it isn't run in the Paperscope.
My question is: are my findings correct? Am I doing something wrong? What is the right way to divide a Paper.js application into multiple units for readability?
Of course I can get it running, but I want to make sure I do it right.
This is indeed how it works. I've opened an issue on GitHub
I found that the "cleanest" way is to do it with this.install(window). It also makes error finding with Chrome developer tools easier since it is more adapted to reporting on the line errors in java-script than "paperscript".
in index.html (for example):
<script type="text/javascript" src='js/other_lib.js'></script>
<script type="text/paperscript" canvas="canvas">
this.install(window);
/*no code 'required' here */
</script>
<body>
<canvas id="canvas" width="1500" height="500"></canvas>
</body>
Then in the js/other_lib.js i just add code as normal:
var r = new Path.Rectangle([100,100],[200,200]);
r.fillColor = 'black';
/*more code here*/
This should generate a rectangle.
What DOES'T NOT WORK for me (as of Paper.js v0.10.2 Release Date: 9. July 2016) is the object operators. Such as adding vecrots pointc = pointa + pointb; for me this is giving a lot of NaN values.
I have had to edit a few libs to get this working, but the change is simple:
var pointc = new Point(pointa.x+pointb.x,pointa.y + pointb.y);
Hi I've tried this a couple of ways and I'm not sure what I'm missing. The documentation here https://developers.google.com/maps/documentation/javascript/reference states that I should be able to set the center of my Map using the coordinates like this:
setCenter(latlng:LatLng)
which I am guessing means I can use the syntax:
myMap.setCenter(-37.8025182,144.9987055);
but I get the error "Uncaught Error: Invalid value for property : -37.8025182 "
Is there something I'm missing - the documentation doesn't really give me any clues.
Regards,
Lea.
The documentation says the single argument for setCenter is a LatLng. setCenter doesn't take two Numbers.
var centerpoint = new google.maps.LatLng(-37.8025182,144.9987055);
myMap.setCenter(centerpoint);
or combine everything together:
myMap.setCenter(new google.maps.LatLng(-37.8025182,144.9987055));
