QUESTION
Here's a codepen demonstrating a treetable with groups:
https://codepen.io/dharmatech/full/mdWGbox
ScreenshotScreenshot of the above treetable:
The IssueOnly some of the columns are shown; there are many more available. However, note that there is no horizontal scrollbar shown at the bottom to bring the other columns into view.
Is there a way to turn on a horizontal scrollbar?
Approaches I've exploredI've tried each of these:
...ANSWER
Answered 2021-Jun-11 at 09:04Your code is correct. And TreeTable does show all columns, you just miss the horizontal scroll at bottom of the grid.
To fix the situation, you need to
- init UI in container ( currently it is atached to the body ). To do so you need to add
containerproperty to the UI configuration
QUESTION
Currently trying to create attraction effect on 3D cubes using createVector function. The attraction designed to trigger when mouse pressed but currently it's stating the error:
...ANSWER
Answered 2021-Jun-08 at 11:29- You're using index
afor argument ofCubes.attractionwhich is expecting an object with aposvector field (a Cubes ?) - You're trying to position your cubes using
this.x/this.y, which aren't changed byupdate. Use thethis.posvector instead - You can optimize by checking for mouse pressed only once, and only then calling
attractionon every cube with mouse coordinates as vector argument - In physics, force drives acceleration, not velocity. I changed that but maybe it was deliberate of you.
- You should change your class name to
Cuberather thanCubes
QUESTION
I have been trying to figure out how to add certain words when objects hit each other on my processing code. Would anyone know how I would get my screen to say 'You Have Won' when the red ball that is getting launched touches the black circle on the top half of the screen? I was wondering what needs to be done in order to achieve this.
This is my code:

QUESTION
Below I have two dataframes, the first being dataframe det and the second being orig. I need to compare det['Detection'] with orig['Date/Time']. Once the values are found during the comparion, I need to copy values from orig and det to some final dataframe (final). The format that I need the final dataframe in is det['Date/Time'] orig['Lat'] orig['Lon'] orig['Dep'] det['Mag'] I hope that my formatting is adequate for folks. I was not sure how to handle the dataframes so I just placed them in tables. Some additional information that probably won't matter is that det is 3385 rows by 3 columns and orig is 818 rows by 9 columns.
det:
orig:
final:
ANSWER
Answered 2021-Jun-01 at 20:17You can merge the two dataframes, since you want to use Detection column from the first data frame and Date/Time column from the second dataframe, you can just rename the column of second dataframe while merging since the column name already exits in the first dataframe:
QUESTION
I have a 498-frames-long image sequence for which I calculated optical flow using cv2.calcOpticalFlowFarneback. Therefore now I have 497 vector maps representing my motion vectors, and these vector are described by magnitude and direction.
What I need to do is to generate a histogram where on the x-axis I have angle ranges in degrees. More specifically, I have 12 bins where the first bin contains all the vectors with direction 0 < angle < 30, the second one 30 < angle < 60 and so on. On the y-axis, instead, I need to have the sum of the modulus of those vectors contained in each bin.
The problem here is that doing all of this using simple for loops and if statements takes ages:
ANSWER
Answered 2021-Jun-01 at 01:10Conditionals are slow. You should avoid them as much as possible. Also Numpy vectorization and Numba JIT help to speed up such a code by a large margin. Here is an untested example:

QUESTION
I am reading an image, getting objects that have a certain brightness value, and then plotting the X and Y coords to the image.
But, there is a huge group of outliers, which are all located in a rectangular part of the image, Its X and Y coords are 1110-1977 (width) and 1069-1905 (height). From here, I'm looping through this little square portion of the image, and from my pre-created x and y arrays any values that have the same coords as shown there are removed.
However, this removes a lot more coords, which, for example, have X in the range 1110-1977. So the end result is a cross pattern filtering when I only want the square in the center to be filtered. How would I do this?
Code
...ANSWER
Answered 2021-May-25 at 02:35Your post-processing logic is flawed. You remove a bunch of X values in the range 1110-1977, without checking whether its corresponding Y value is also in the range of the box. Remove this code section instead and add that logic the first time you loop to gather your x and y coords.

This is my code:
...ANSWER
Answered 2021-May-21 at 11:06To solve the isseu, you need to know the bound of your curve. You have to change the the orthographic projection:
glOrtho(-6, 6, -6, 6, -1, 1);
In Orthographic Projection, the view space coordinates are linearly mapped to the clip space coordinates. The viewing volume is defined by 6 distances (left, right, bottom, top, near, far). The values for left, right, bottom, top, near and far define a cuboid (box).
If you want to center the view on the curve, the center of the projection must be the center of the curve. e.g.:

i ran into following error an cannot find an solution.
...ANSWER
Answered 2021-May-20 at 16:49and user with same problem,
the gotten error is because updated the libraries and is causing by an annotation inside the viewholder.
@ViewModelInject is depricated and needs do replaced by @Inject and the class needs to be annotated with @HiltViewModel.
