I am new to ag-grid angular. I want to implement a functionality where i can find each column values and replace with new values in a single column.
As ag-grid does not provide a way to Find/Replace , you can use the below algorithm to do it.
foundCell = [];
foundIndex = 0;
message = '';
//Find text in ag-grid
find(findText: string) {
let found = false;
let rowNodes: any = [];
let focusedCell = this.gridApi.getFocusedCell();
if (focusedCell) {
let lastFoundObj: any;
if (this.foundCell.length > 0) {
lastFoundObj = this.foundCell[this.foundCell.length - 1];
if (!(lastFoundObj.rowIndex == focusedCell.rowIndex && lastFoundObj.field == focusedCell.column.colId)) {
this.foundCell = [];
this.foundIndex = focusedCell.rowIndex;
}
}
}
this.gridApi.forEachNode(function (node,rowIndex) {
rowNodes.push(node);
});
for(let i=this.foundIndex; i < rowColumnData.rowNodes.length ; i++) {
let node = rowColumnData.rowNodes[i];
var rowObj = node.data;
found = false;
for (var key in rowObj) {
if (rowObj[key].includes(findText) && !this.checkIfAlreadyFound(key, node.rowIndex)) {
found = true;
this.foundCell.push({ 'field': key, 'rowIndex': node.rowIndex});
break;
}
}
if (found) {
break;
}
}
if (found) {
let lastFoundCell = this.foundCell[this.foundCell.length-1];
this.gridApi.ensureIndexVisible(lastFoundCell.rowIndex, 'middle');
this.gridApi.ensureColumnVisible(lastFoundCell.field);
this.gridApi.setFocusedCell(lastFoundCell.rowIndex,lastFoundCell.field);
this.found = true;
} else {
this.foundIndex = 0;
this.foundCell = [];
this.found = false;
this.message = 'Not found';
}
}
//Replace text in ag-grid
replace(findText: string, replaceWith: string, isReplaceAll: boolean) {
if (this.found || isReplaceAll) {
let focusedCell: any;
var cell: any;
let rowNodes = [];
focusedCell = this.gridApi.getFocusedCell();
if (focusedCell) {
cell = { rowIndex: focusedCell.rowIndex, field: focusedCell.column.colId };
} else {
cell = this.foundCell[this.foundCell.length - 1];
}
this.gridApi.forEachNode(function (node,rowIndex) {
rowNodes.push(node);
});
var rowNode: any;
var newCellValue: any;

let allfoundCell = this.findAllCells(rowNodes,findText);

if (newCellValue != rowNode.data[cell.field]) {

}
}
this.found = false;
}

Hi I need help finding coordinate or points offset from two endpoints of a line. In my program, I would like to specify the two points and the offset. Then I need to calculate the two offset coordinates.
I worked something out using trigonometry but it only works in some cases and when the line is in the positive quadrant.
Here is an image describing what I need to find:
Points on line
Ok so I need to find X3,Y3 and X4,Y4 coordinates.
My method I followed:
Calculate angle:
Ang = atan((Y2 - Y1)/(X2 - X1))
To find X3:
X3 = X1 + Offset * Cos(Ang)
The same concept for Y3
The issue is that if the line is in a different quadrant the point info is not correct... Any help, please.
This question is a clear case for using 2d vector math. The idea is that we subtract p1 from p2 to give us a vector that describes the length and direction of the line. We then normalize this vector, such that it has a length of 1. If you then multiply this normalized vector with the number of units you'd like to move away from the end and add the result to the end-point, you'll have a new point.
Consider an example walking along the x axis:
p1 = 0,0
p2 = 10,0
dif = p2 - p1 = (10,0)
length is 10, so it's 10 times too long - we divide it by 10 to get a vector 1 unit long.
If we then move 5 times (1,0), we end up at 5,0 - 5 units away, bewdy!
Here's a function that achieves the same thing:
function calcOffsetPoint(x1,y1, x2,y2, distTowardsP2fromP1)
{
var p1 = new vec2d(x1,y1);
var p2 = new vec2d(x2,y2);
var delta = p2.sub(p1);
var dirVec = delta.clone();
dirVec.normalize();
dirVec.timesEquals(distTowardsP2fromP1);
var resultPoint = p1.add(dirVec);
return resultPoint;
}
As you can see, this makes use of something I've called vec2d. There's a copy of it in the following snippet:
"use strict";
function byId(id){return document.getElemetById(id)}
function newEl(tag){return document.createElement(tag)}

var end1 = new vec2d(0,0);
var end2 = new vec2d(10,0);
var midPoint = calcOffsetPoint(end1.x,end1.y, end2.x,end2.y, 5);
console.log( midPoint.toStringN(2) );
}

}
I had some spare time over the weekend, so put together a working demo of the image you posted. Have a play around. Make sure you run it in full-screen, so you can see the sliders that set the offsets for p3 and p4. Disregard the coordinate-system transformation stuff, that's just there to allow me to make an image the same dimensions as your image yet conveniently display it in a window with about 5% the area. The questions come from the exercise section of some old text-book I was reading over the weekend.

i'm looking for a way to select items in the render queue via script.
i'm creating a listBox that contains all the RQ items ( i need to list them in a simpler way then the RQ window, and i'm keeping the index number of each item), and i want to select from that list items and select them in the RQ.
ideas?
thanks

Below code is a copy with minor edits from https://github.com/GoogleChrome/chrome-app-samples/tree/master/serial/ledtoggle. I am able to send a byte and receive a reply. I am not able to get an TimeoutError event in case of reply is not sent by the client. I have set timeout to 50 ms.
this.receiveTimeout = 50;
Entire code follows.
const DEVICE_PATH = 'COM1';
const serial = chrome.serial;
var ab2str = function(buf) {
var bufView = new Uint8Array(buf);
var encodedString = String.fromCharCode.apply(null, bufView);
return decodeURIComponent(escape(encodedString));
};
var str2ab = function(str) {
var encodedString = unescape((str));
var bytes = new Uint8Array(1);
bytes[0] = parseInt(encodedString);
}
return bytes.buffer;
};
var SerialConnection = function() {
this.connectionId = -1;
this.lineBuffer = "";
this.receiveTimeout =50;
this.boundOnReceive = this.onReceive.bind(this);
this.boundOnReceiveError = this.onReceiveError.bind(this);
this.onConnect = new chrome.Event();
this.onReadLine = new chrome.Event();
this.onError = new chrome.Event();
};
SerialConnection.prototype.onConnectComplete = function(connectionInfo) {
if (!connectionInfo) {
log("Connection failed.");
return;
}
this.connectionId = connectionInfo.connectionId;
chrome.serial.onReceive.addListener(this.boundOnReceive);
chrome.serial.onReceiveError.addListener(this.boundOnReceiveError);
this.onConnect.dispatch();
};
SerialConnection.prototype.onReceive = function(receiveInfo) {
if (receiveInfo.connectionId !== this.connectionId) {
return;
}
this.lineBuffer += ab2str(receiveInfo.data);
var index;
while ((index = this.lineBuffer.indexOf('$')) >= 0) {
var line = this.lineBuffer.substr(0, index + 1);
this.onReadLine.dispatch(line);
this.lineBuffer = this.lineBuffer.substr(index + 1);
}
};
SerialConnection.prototype.onReceiveError = function(errorInfo) {
log('Error');
if (errorInfo.connectionId === this.connectionId) {
log('Error');
this.onError.dispatch(errorInfo.error);
log('Error');
}
log('Error');
};
SerialConnection.prototype.connect = function(path) {
serial.connect(path, this.onConnectComplete.bind(this))
};
SerialConnection.prototype.send = function(msg) {
if (this.connectionId < 0) {
throw 'Invalid connection';
}
serial.send(this.connectionId, str2ab(msg), function() {});
};
SerialConnection.prototype.disconnect = function() {
if (this.connectionId < 0) {
throw 'Invalid connection';
}
serial.disconnect(this.connectionId, function() {});
};
var connection = new SerialConnection();
connection.onConnect.addListener(function() {
log('connected to: ' + DEVICE_PATH);
);
connection.onReadLine.addListener(function(line) {
log('read line: ' + line);
});
connection.onError.addListener(function() {
log('Error: ');
});
connection.connect(DEVICE_PATH);
function log(msg) {
var buffer = document.querySelector('#buffer');
buffer.innerHTML += msg + '<br/>';
}
document.querySelector('button').addEventListener('click', function() {
connection.send(2);
});
Maybe I'm reading the code incorrectly, but at no point do you pass receiveTimeout into chrome.serial. The method signature is chrome.serial.connect(string path, ConnectionOptions options, function callback), where options is an optional parameter. You never pass anything into options. Fix that and let us know what happens.

The registIMEKey method is part of the Plugin API.
var pluginAPI = new Common.API.Plugin();
pluginAPI.registIMEKey();
See: http://www.samsungdforum.com/Guide/ref00006/common_module_plugin_object.html#ref00006-common-module-plugin-object-registimekey
Edit: Updated to add code solution.
widgetAPI no contains method registIMEKey();, it contains in IMEShell.
