This is a simple example to display read-only data that is tabular in nature using Qt's Model/View Framework. Specifically, the Qt Objects QAbstractTableModel (sub-classed in this example) and QTableView are used.
Implementations of the methods rowCount(), columnCount(), data() and headerData() are...
Use case scenario:
A table view consists of different columns with different data format that needs to be transformed with different pipes.

Method references make excellent self-documenting code, and using method references with Streams makes complicated processes simple to read and understand. Consider the following code:
public interface Ordered {
default int getOrder(){
return 0;
}
}
public interface Valued<...

If we want to get the x-cordinate of origin of the view, then we need to write like:
view.frame.origin.x
For width, we need to write:
view.frame.size.width
But if we add a simple extension to an UIView, we can get all the attributes very simply, like:
view.x
view.y
view.width
view.height...
Magento custom module development is a core part of any Magento development or Magento project, because at any stage you may want to integrate your own functionality/module in your existing Magento project.
The first thing developers should disable is the system cache. Otherwise developing will bec...
When working with existing model that is quite big and is being regenerated quite often in cases where abstraction needed it might be costly to manually go around redecorating model with interfaces. In such cases one might want to add some dynamic behavior to model generation.
Following example wil...
Some ADO.NET providers (most notably: OleDB) do not support named parameters; parameters are instead specified only by position, with the ? place-holder. Dapper would not know what member to use for these, so dapper allows an alternative syntax, ?foo?; this would be the same as @foo or :foo in other...
For efficiency, data.table offers a way of altering a data.frame or list to make a data.table in-place:
# example data.frame
DF = data.frame(x = letters[1:5], y = 1:5, z = (1:5) > 3)
# modification
setDT(DF)
Note that we do not <- assign the result, since the object DF has been modifi...
Examples of monotonic predicates are:
unification with (=)/2 or unify_with_occurs_check/2
dif/2, expressing disequality of terms
CLP(FD) constraints like (#=)/2 and (#>)/2, using a monotonic execution mode.
Prolog predicates that only use monotonic goals are themselves monotonic.
Monoton...
In general, UWP is used for making a single application that runs on Windows 10 across many different devices. However, it is also possible to make code tailored to specific devices. You can achieve this in several different ways.

The thing is; you can't connect Ionic to any database (MySQL, Postgres, MSSQL, ...) directly. The keyword here is directly.
No, there's no workaround, no magic involved, it's just not the way this is supposed to work. Ionic works on top of Angular and Angular is a frontend framework.
However, the ...
If your team is following a rebase-based workflow, it may be a advantageous to setup git so that each newly created branch will perform a rebase operation, instead of a merge operation, during a git pull.
To setup every new branch to automatically rebase, add the following to your .gitconfig or .gi...
