Circles

Basically there are rectangles (buildings) and circles (people).

The task I need to do is basically, when a function "fg" is called, every circle that is inside a given radius needs to run to the closest rectangle, and after all the circles inside the radius finds a rectangle, I need to report on a .txt file the names of the circles that run to each rectangle sorted alphabetically.

Such as:

Rectangle A: c1 c2 c3

Rectangle B: c7 c11 c20

...

And so on...

I need to store the addresses of the circles that run, on a vector of each rectangle. I tried to use qsort from stdlib.h, but maybe the function that i use to compare is wrong

(EDIT - full code to better understand):

The design is for a website built on Angular . Have been using canvas along with html . canvas is used for building the dotted and solid arrows around circle . html is used for designing circles.

I'm trying to achieve exactly the same animation shown below

.

and my output using UIBezierPath and CABasicAnimation is this below.

Here is my LoaderView code

I'm trying to create a map with a very large amount of Circle objects. these Circles' colors will change based on a user input. A lot of colors can change at once, and I want to present the changes as fast as possible.

To save up on the time of creating the Circles each time the user changes something and the map re-renders, I thought about storing the Circle objects in an array in the state. Then when the user changes something, I would want to update the Circles' properties, but without using copy methods and the like (as it contradicts the idea of creating the Circle objects only once).

I thought about making a parallel array that stores the colors, which will be updated by the user, and to store in each Circle object's pathOptions a reference to the parallel location in this array, but am not sure how to do this.

Alternatively I would be glad to hear any other directions on how to optimize the speed.

basic version, app loads Circles from array correctly, colors are static:

With the below code, I want to plot two filled circles over the two dashed lines. What I want is that the dashed lines should not be visible in the filled circular region (shown by red) in both the circles. How can I do this in Python ?

I'm drawing circle diagram using my own inbuilt libraries. I'm able to draw circles using table data (x1,y1 & r) ,sharing code
I'm using datachange signal with table, whenever enter any table item data then its creating no. of graph with circles. Is there other signal I can use or what change can make in code ? I want single graph with no. of circles(based on no. of entries in table).
Also when circles are drawn lines coming like we draw without removing our pen to draw another circle how to overcome this ?

• CHPlotGraph2D - this class to create graph

• CHPlotCurveData- this Class hold the data points for the curves

• CHPlotCurve-Class to draw the data as a line curve

  CHPlotCurveData* curvedata1 = new CHPlotCurveData();
  QAbstractItemModel* table1 = ui.tableView->model();
  for (int irows = 0, maxI = table1->rowCount(); irows < maxI; ++irows)
  {
  double x1 = table1->data(table1->index(irows, 1)).toDouble();
  double y1 = table1->data(table1->index(irows, 2)).toDouble();
  double r = table1->data(table1->index(irows, 6)).toDouble();
  for (double angle = 0; angle <= 360; angle++)
  {
  double theta = (angle * 180) / 3.14;
  double zx = x1 + r * cos(theta);
  double zy = y1 + r * sin(theta);
  QPointF pt(zx, zy);
  curvedata1->append((pt));
  }
  }
  CHPlotCurve* curve1 = (CHPlotCurve*)pGr->insertCurve("circle",
  CHPlotGraph2D::Line, false );
  curve1->setSamples(curvedata1);
  connect(ui.tableView->model(), &QAbstractItemModel::dataChanged,
  this, &tablemodel::drawCircle);

I used the following code to draw a circle in my world. Now I want to replace it with an single image, but I have no idea how to do that.

I'm using the "Progress circle" widget (version 2.0.0) in Mendix Studio Pro 9.2.0, and I would like to individually change the color(s) of each one of my progress circles, primarily the part that is shown in blue by default. By looking into Chrome DevTools, I found that the attribute stroke might be storing the color, but I'm not sure. Adding stroke: red in the Appearance > Common > Style form didn't work. On the other hand, adding background: red did have the intended effect of changing the background of the progress circle.

Can anyone help? I'm quite new to Mendix, so any help from you would be greatly appreciated.

I have to create a simple Text Editor which has menu bar with specific options.

One of them is to change font colors by selecting it on JRadioButtonMenuItem which has to look exactly as professor described in the picture.

My problem is that I don't know how to create and add those little circles between text and radio button.
