I've created a class that extends the Window SmartGWT class, and it is set to be modal. I am trying to make the Window close when a user clicks off the window. I have tried to link it up to a FocusChangedHandler with no luck. Has anyone done something like this before?

I guess according to your requirement, you need to implement this property of Window:
this.setDismissOnOutsideClick(true);

When a function is inherited by a subclass, I want the return type to be as if the function were defined directly on the subclass.
To be clear, the code works fine at run-time. But I want to take advantage of static type-checking. I'm getting red squiggly lines in VScode and warnings from Google-Closure-Compiler. I'm not sure if this is an issue with my ES6 code or with my type annotations.
My trivial example ES6 classes:
// #ts-check
"use strict";
export class db_row {
/**
* #param {number} id
*/
constructor(id) {
/** #type {number} */
this.id = id;
}
clone() {
return new db_row(this.id);
}
}
export class Channel_row extends db_row {
/**
* Constructor
* #param {*=} init
* #param {string=} name
* #param {string=} value
*/
constructor(init, name, value = '') {
let id = -1;
if (typeof init == 'object') {
id = init.id;
name = init.name;
value = init.value;
} else if (typeof init == 'number') {
id = init;
}
super(id);
this.name = name;
this.value = value;
}
clone() {
return new Channel_row(this.id, this.name, this.value);
}
}
export class db_table {
/**
* Constructor
* #param {Array<db_row>} table
*/
constructor(table) {
/**#type {Array<db_row>} */
this.table = table;
}
/**
*/
get_table_copy() { return this.table.map(item => item.clone()) }
/**
* #param {?number=} id
*/
get_row_by_id(id) {
const row = this.table.filter(item => item.id === id)[0];
if (row) return row.clone();
return null;
}
}
export class Channel_table extends db_table {
constructor() {
/**#type {Array<Channel_row>} */
let table = [];
super(table);
}
}
// Test code below:
/**
*
* #param {Channel_row} chan_row
*/
function print_chan_row(chan_row) {
console.log(chan_row.name);
}
let channel_table = new Channel_table();
let channel_row = channel_table.get_row_by_id(0); // hover reports that the type of channel_row is db_row, when it should be type Channel_row
print_chan_row(channel_row); // Red squiggly line error: Argument of type 'db_row' is not assignable to parameter of type 'Channel_row'. Type 'db_row' is missing the following properties from type 'Channel_row': name, valuets(2345)
console.log(channel_row.name); // Red squiggly line error: Property 'name' does not exist on type 'db_row'.ts(2339)
let channel_table_2 = channel_table.get_table_copy(); // hover reports that the type of channel_row is db_row[], when it should be type Channel_row[]
print_chan_row(channel_table_2[0]); // Red squiggly line error: Argument of type 'db_row' is not assignable to parameter of type 'Channel_row'.ts(2345)
Now, if I move or copy the get_row_by_id() and get_table_copy() functions into the subclass, the type errors go away. But I don't want to duplicate code unnecessarily.
How can I declare the functions in the parent class so it can be reused in child classes, but maintain the static type checking?
As a bonus, can I also generalize the clone() function so it doesn't need to be over-ridden in subclasses of db_row?
How to retrieve a random word of a given length from a Trie
The answer above explains how to select the first character but I am confused how we will proceed after that. I want words of Length L but when I start traversing the tree, I wouldn't know if the branch that is being traversed has depth L.

Yes, he only shows how to choose first character from root node. However, after you update your currentNode following that character, you can apply exact same principal to find next character from the new node. Another way of viewing what his algorithm did is, given a node, an integer L(5 in his example), finds i'th (1234 in his example) word which is in the subtree of that node and is exactly L depth away from it.
So after you have made your first move, you can recursively call that algorithm from new node, with L-1 as depth. This is basic idea. Of course,some details need to be filled.
Firstly, updating i before next recursive call. Say algorithm chose first character to be d. And first 3 letters i.e a b c combinedly had 1000 5-letter words. So now, you need to find (1234-1000)=234th word from this new node.
Secondly, instead of having lengthFrequencyByLetter and totalLengthFrequency for entire tree,now you need to have them for every single node, which will require lots of ram. (you can optimize that by using HashMap though.)
A very high level implementation could be:
String randomWord(Node currentNode,int L,int index){
if(L==0) return node.wordContainedWithin();
char ch = find_next_character(node,L,index); //'d' in our example
newNode = currentNode.getChild(ch); //node following d
//following example, words_before = 1000
int words_before = sum(lengthFrequencyByLetter[x][L] of all x before ch)
int new_index = index - words_before;
return randomWord(newNode,L-1,new_index);
}
Now to get a random L-letter word, look up root's totalLengthFrequency[L], generate a number i (1234 here) between 0 to that value, and call randomWord as:
randomWord(tree.root,L,i)
I had installed an custom extension. Its running successfully and had all files at its place. But I am getting this error on my listing page
Fatal error: Call to a member function setFinalPrice() on a non-object in /var/zpanel/hostdata/zadmin/public_html/unisport_com/app/code/core/Mage/Sales/Model/Quote/Item/Abstract.php on line 89.
I google this error but did'nt found any proper solution. One solution is to copy the original Abstract.php file may be because extension had overwrite this file. But I checked the code from the backup its the same and also copied original file but nothing worked for me.
What is wrong with this file? Can anybody help?
below is the code of Abstract.php file:

What I need to do is extract a 2D DataMatrix (bitmap) bar code and read it. I can make this work however, I have to loop through all the images on every page. This is taking a long time when I have 1000’s of pages, so I was wondering if it was possible to define a location(rectangle)of where the image(barcode) was and just extract that image?
The bar code is always i the same location.
note: I'm using Spire.Barcode from e-IceBlue
Thank you for any help.
CODE RenderFilter snippet:
public class MyRegionTextRenderFilter : RenderFilter {
/** the region to allow text from */
private RectangleJ filterRect;
public PdfImageObject image;
/**
* Constructs a filter
* #param filterRect the rectangle to filter text against. Note that this is a java.awt.Rectangle !
*/
public MyRegionTextRenderFilter(RectangleJ filterRect) {
this.filterRect = filterRect;
}
/**
* Constructs a filter
* #param filterRect the rectangle to filter text against.
*/
public MyRegionTextRenderFilter(iTextSharp.text.Rectangle filterRect)
{
this.filterRect = new RectangleJ(filterRect);
}
/**
* #see com.itextpdf.text.pdf.parser.RenderFilter#allowText(com.itextpdf.text.pdf.parser.TextRenderInfo)
*/
public override bool AllowImage(ImageRenderInfo renderInfo)
{
var matrix = renderInfo.GetImageCTM();
float left = matrix[6];
float top = matrix[7];
float width = matrix[0];
float height = matrix[4];
return filterRect.IntersectsLine(left, top, width, height);
}
}
Code calling :
RectangleJ rect = new RectangleJ(518.0f, 18.0f, 23.0f, 23.0f);
PdfReaderContentParser parser2 = new PdfReaderContentParser(pdfReader);
RenderFilter[] renderFilter = new RenderFilter[1];
renderFilter[0] = new MyRegionTextRenderFilter(rect);
FilteredTextRenderListener listener2 = new FilteredTextRenderListener(new LocationTextExtractionStrategy(), renderFilter);
parser2.ProcessContent(3, listener2);
The parser namespace of iText(Sharp) allows filtering of information digested by an IRenderListener implementation by using a RenderFilter:
public abstract class RenderFilter {
/**
* #param renderInfo
* #return true if the text render operation should be performed
*/
public virtual bool AllowText(TextRenderInfo renderInfo){
return true;
}
/**
*
* #param renderInfo
* #return true is the image render operation should be performed
*/
public virtual bool AllowImage(ImageRenderInfo renderInfo){
return true;
}
}
For filtering by area there already is a textual render filter, the RegionTextRenderFilter.
For your task simply copy it and add an AllowImage(ImageRenderInfo renderInfo) implementation similar to the existing AllowText(TextRenderInfo renderInfo) method.
I've created an RCP application with an interactive splash for logging onto my system. I built it on a Mac, and the application works perfectly, but when I created a new product configuration for Windows and run the application, it launches without the splash and there are no errors appearing in the console.
The splash handler code is as follows

Oddly enough, the bitmap (created in Photoshop/Mac) image was seen as corrupt in Eclipse, but opened fine in all graphics applications (including Photoshop/Win). I opened the file in MS Paint and saved without changes. The splash started working fine.
Check your bitmap if you get this error!
