You don't need to "change the y coordinate", you just need to use the correct arguments to create the rectangle. There are various ways to initialize a QRect, you are using the two points, another one (and more common) is to use the coordinates of the origin and the size of the rectangle.

Once you know the width, you can compute the height, and make it negative if the y of the end point is above the begin.

Note that in this way you could get a "negative" rectangle (negative width, with the "right" edge actually at the left, the same for the height/bottom), so it's usually better to use normalized, which also allows you to get the correct coordinates of the rectangle for screen grabbing.

You need to validate your data, first when the app runs lists is undefined and throws an error. change your render method to the following.

you can create a TextShape deriving from Shape, having Text, Font, Location and Color properties and treat it like other shapes, so redo and undo will not be a problem.

Here are some tips which will help you to solve the problem:

• Create a base Shape class or interface containing basic methods like Draw, Clone, HitTest, etc.
• All shapes, including TextShape should derive from Shape. TextShape is also a shape, having Text, Font, Location and Color properties.
• Each implementation of Shape has its implementation of base methods.
• Implement INotifyPropertyChanged in all your shapes, then you can listen to changes of properties and for example, add something to undo buffer after change of color, border width, etc.
• Implement IClonable or base class Clone method. All shapes should be clonable when adding to undo buffer.
• Do dispose GDI objects like Pen and Brush. It's not optional.
• Instead of adding a single shape to undo buffer, create a class like drawing context containing List of shapes, Background color of drawing surface and so on. Also in this class implement INotifyPropertyChanged, then by each change in the shapes or this class properties, you can add a clone of this class to undo buffer.

Here is an example of Shapeclass:

You are not supposed to edit these files using vi, just write values using echo. Vim will try to create a file in the same directory and rename it over the latency_timer file which does not work in /sys

Instead, use something like:

Justify-content doesn't work as intended because every article you have is using position: absolute. When you use position: absolute, the position of the element only cares about the top, left, right, bottom attributes.

Also, you don't need individual styling for each article, since each article looks the same.

Just have one class called .article and put all your styling there. Remove the positioning and let flexbox take care of it for you.

EDIT:

The OP's solution is also part of the overall answer.

OP's answer:

I found the solution, one of the parent (grand-grand parent) containers was not at 100 % height. And since Stackoverflow only allows 30000 characters in the code field, I could not post the whole code with the many parent containers.

It took me a moment to understand what you're looking to do. It seems you plan to import a CSV file and read the Header line. You then want to be able to Map the Column Headers in your App.

Consider the following code. I populated variables, assuming all the data has been imported from the CSV and JSON already/

you can use ExecuteGroovyScript processor with following code:

I will cite the official Windows documentation. Although the doc is about Native API, Winforms uses the same underlying technology:

An application invalidates a portion of a window and sets the update region by using the InvalidateRect or InvalidateRgn function. These functions add the specified rectangle or region to the update region, combining the rectangle or region with anything the system or the application may have previously added to the update region.

The InvalidateRect and InvalidateRgn functions do not generate WM_PAINT messages. Instead, the system accumulates the changes made by these functions and its own changes. By accumulating changes, a window processes all changes at once instead of updating bits and pieces one step at a time.

Calling .NET Refresh() is equivalent of calling InvalidateAll() + Update(). InvalidateAll marks the whole screen as invalid, and Update() forces the process of redrawing what's invalid, so the whole screen. You can optimize your program if you just invalidate "manually" what you know has changed.

That's what I did in my modified sample. Instead of calling Refresh(), I added a new oldRcRect variable to be able to invalidate old state and new state, and a RefreshOnMove() method like this (and I replaced most Refresh calls by a RefreshOnMove call) :

You need to store points in a list and then to have a smooth drawing, draw a curve based on those points using DrawCurve. Also you need to setup a wide pen with suitable settings (For example Round) for LineJoin, StartCap and EndCap, then you can have a highlight drawing like following:
