QUESTION
I'm trying to build a panel with components laid out horizontally, with auto-wrap if not enough place and a vertical scrollbar.
Something like this:
...ANSWER
Answered 2019-Sep-27 at 09:10The code below works for me.
I have split the code into a component that does all the layout and the test code to verify that it works (in the static main
) method.
Instead of hooking to resize events on the JScrollPane, I do that on the whole TestFlow (TF) component - I believe this is equivalent, but it seems safer. Whenever the TF is resized, I update the preferred size of the panel, just as you did - but there are two steps that you were not taking:
- the width of the inner panel will be whatever width the outer panel has been asigned, but should also leave enough space for the vertical scrollbar, if it is needed.
- the height of the inner panel should be that of the lowest component that it is displaying. In my case, I am taking the shortcut of assuming that all components in the lowest row are of equal height, but this need not be always true.
Diving into how Swing handles layout and painting, and which of the several similar-looking methods get called when by whom always makes me think of dark magic.
QUESTION
ANSWER
Answered 2018-Nov-17 at 07:59You should do a water pane, flat and rectangular. The world pane should have a depth, where the water can clip through it. So the terrain (the bank of the river) has to be irregular.
(Sorry for my poor drawing skills)
You can create a terrain any depth and shape you want with heightmapping.
Here is a good example how to create a terrain from heightmap.
QUESTION
I have data like the sample below. It's very large and I would like to sample first 10 items from it. It looks like a list of dicts, but if I try user_train[:5] I get an error. I can sample one item at a time like user_train[4] works. Any tips are greatly appreciated.
code:
...ANSWER
Answered 2018-Jun-27 at 03:49If you wanted to find a way around it. You could go:
sample = [user_train[x] for x in range(10)]
This is called a list comprehension, unhashable type error is usually due to trying to convert a dict to a list.
QUESTION
I am having problem accessing the variable int i inside the inner class Code:
...ANSWER
Answered 2018-Jun-22 at 10:46Only effectively final variables can be accessed from anonymous classes.
i
is modified by the loop, so it is not effectively final.
A workaround would look like this:
