kandi X-RAY | CrossLine Summary
CrossLine is an outliner with sophisticated cross-link capabilities in the tradition of the well-respected Ecco Pro. It implements the concept of "Transclusion" proposed by Ted Nelson and - among others - implemented in the legendary Objectory SE tool by Ivar Jacobson. It is also a full text database with built-in search engine. An outliner (or outline processor) is a specialized type of text editor (word processor) used to create and edit outlines, which are text files which have a tree structure, for organization. Textual information is contained in discrete sections called "nodes", which are arranged according to their topic–subtopic (parent–child) relationships, sort of like the members of a family tree. When loaded into an outliner, an outline may be collapsed or expanded to display as few or as many levels as desired (see

QUESTION
I found on github these lines of code and spend more than hour trying to understand.
...ANSWER
Answered 2021-Aug-17 at 06:53I am learning Kotlin myself and thought I can help with the code snippet above.
SearchView.OnQueryTextListener is an interface with onQueryTextChange and onQueryTextSubmit methods - reference - https://developer.android.com/reference/kotlin/android/widget/SearchView.OnQueryTextListener
SearchView.onQueryTextChanged function looks like an extension function on SearchView, which accepts a lambda named listener.
The listener lambda itself is a function which takes a string as param and returns Unit ie returns nothing. That means the function will do some side-effect eg IO, update some state etc.
Since onQueryTextChanged is an extension function, you get the reference to the object on which this function will be called as this in the function body
object : SearchView.OnQueryTextListener part is basically an object implementing the SearchView.OnQueryTextListener interface with both the methods from the interface overridden.
The object in above step is passed as param to setOnQueryTextListener method.
At the caller site, i.e.
QUESTION
I am trying to implement the same functionality in my widget as it is in cv:: namedWindow.
The goal is to enable zooming and to make the overlay with the grid and the values of pixel's colors directly over the original pixmap. Here is the example: сv picture zoomed:
I inherited the QGraphicsView widget, added to QGraphicsScene the QGraphicsPixmapItem and reimplemented the QWheelEvent so that zooming in and out works correctly now. The problem starts with creating an overlay.
Instead of creating a pack of QGraphicsLineItems and adding them to the scene in order to make the grid, I inherit the QGraphicsRectItem and draw the whole grid on it.
...ANSWER
Answered 2021-Feb-16 at 10:31I finally watched through the openCV source code and found what I looked for.
The answer for me was the QTransform matrix. OpenCV developers show the image not by using the scene in the QGraphicsView, but actually painting the image directly on the viewport in the paintEvent. The QTransform matrix is stored in the class and is passed to QPainter in the beginning of the paintEvent.
QUESTION
I am having a hard time with a React.js project. I have a TODO list and there is a function to mark a task as done. I have a button next to each and every task and if I click on it the following function will be called.
...ANSWER
Answered 2020-Mar-29 at 05:10.filter() returns an array of the remaining elements. Therefore, taskAfterDeleted and deletedItems are both arrays. You'll need to spread them in your new state:
[...taskAfterDeleted, ...deletedItems]
QUESTION
I'm creating a bunch of plus and minus buttons for a data collection app. I'm using a state machine.
When I press the buttons in my app the TextView that diplays the number is supposed to change, but it doesn't. What did I do wrong?
This is the relevant code:
...ANSWER
Answered 2020-Jan-21 at 23:28As I understand from your response and comments, you did it a little wrong.
onClick() method is not called for every Widget in your layout tree automatically.
What you did is implementing View.OnClickListener to your activity.
So basically your should tell all buttons/views you click to use implemented onClick() method. In your case you need something like this in onCreate() method:
QUESTION
I'm creating an app right now and I'm a little confused. I have 2 files, MainActivity and QrCodeGernerator. Im am doing this for a data collection app. The user inputs data into the MainActivity and the shares it with the QrCodeGenerator which then creates a qr code. The issue is the qr code keeps being null. Any help would be appreciated. MainACtivity is first(I've included snipets related to the question not my whole code)
...ANSWER
Answered 2020-Jan-17 at 23:30I think you want to send Data from one Screen to the other?
https://developer.android.com/training/basics/firstapp/starting-activity
Take a look at Intents, you can use them to start other Activities (go to other screens) and also pass data between screens as shown in the link
In your case you just add String extras or a collection of Strings as one extra to the Intent

Install CrossLine
Follow these steps if you inted to build CrossLine yourself (don't forget to meet the preconditions before you start):.
Create a directory; let's call it BUILD_DIR
Download the CrossLine source code from https://github.com/rochus-keller/CrossLine/archive/master.zip and unpack it to the BUILD_DIR; rename the subdirectory to "CrossLine".
Download the Stream source code from https://github.com/rochus-keller/Stream/archive/github.zip and unpack it to the BUILD_DIR; rename "Stream-github" to "Stream".
Download the Udb source code from https://github.com/rochus-keller/Udb and unpack it to the BUILD_DIR; rename "Udb-github" to "Udb".
Create the subdirectory "Sqlite3" in BUILD_DIR; download the Sqlite source from http://software.rochus-keller.info/Sqlite3.tar.gz and unpack it to the subdirectory.
Download the Txt source code from https://github.com/rochus-keller/Txt and unpack it to the BUILD_DIR; rename "Txt-github" to "Txt".
Download the Oln2 source code from https://github.com/rochus-keller/Oln2 and unpack it to the BUILD_DIR; rename "Oln2-github" to "Oln2".
Download the NAF source code from https://github.com/rochus-keller/NAF/archive/master.zip and unpack it to the BUILD_DIR; rename "NAF-Master" to "NAF". We only need the Gui2 subdirectory so you can delete all other stuff in the NAF directory.
Download the Fts source code from https://github.com/rochus-keller/Fts and unpack it to the BUILD_DIR; rename "Fts-github" to "Fts".
Download the QtSingleApplication source files from https://github.com/qtproject/qt-solutions/tree/master/qtsingleapplication/src and copy them to BUILD_DIR/QtApp directory together with this file: http://software.rochus-keller.info/QtApp.pri
Goto the BUILD_DIR/CrossLine subdirectory and execute QTDIR/bin/qmake CrossLine.pro (see the Qt documentation concerning QTDIR).
Run make; after a couple of minutes you will find the executable in the tmp subdirectory.
