QUESTION
Testing a "DaysContainer". When a days is clicked on, it becomes selected. Works fine when I click test it, but having trouble writing a test for it. Here's my test:
...ANSWER
Answered 2021-Jun-01 at 20:01From the docs: "The framework may combine semantics labels in certain scenarios, such as when multiple Text widgets are in a MaterialButton widget. In such a case, it may be preferable to match by regular expression."
In this case, the selected circle has a superscript.
Replace the string in the finder with a regular expression and the test passes.
QUESTION
I'm trying to write some text onto an image in Pillow, but for some reason it seems to constantly error out about a KeyError. I've tested this with multiple pre-written examples, so I'm fairly sure it's not my code. Here's a copy of the script and the error I'm getting:
...ANSWER
Answered 2021-May-29 at 12:48Probably your problem is that the image you are trying to edit is indexed, that means that it doesn't have RGB colors available, but only a limited palette of colors. So (237,230,211)
is not a RGB tuple, but indexes into the palette of the image.
By converting the image to RGB before trying to draw on it, you should be able to make it work:

I was following a tutorial on how to create a snake game in Java, I followed it and started to add some features in it like a menu system, Game Over screen. Now on this Game Over screen, I wanted to add a restart button, I used "MouseListener" for this. I also added different states for the menu, game, GameOver.
this is my code for MouseListener:
...ANSWER
Answered 2021-May-11 at 21:19You must reset all the variables to the initial values for a new game, simplest way is to define a new method newGame()
, the call this method in the MouseListener (I'm assuming that your MouseInput class is an inner class of GamePanel).
QUESTION
I need to pass an array of integers to a shader as a uniform. As uniform arrays are not yet supported, I'm using a FORMAT_R8
texture/isampler2D to achieve this.
If I'm correctly reading the bytes from the texture, they should be in the range [0..7] and then by normalizing that value, I should get different shades of red, but that's not happening.
In the screenshot you can see that when the value is read as 0, it's correctly displaying it black, but when it's other than 0, it's full red, no shades. I tried comparing the value read and it's always greater than any value I can try, up to the maximum value of a 32 bit signed integer, so no idea what value I'm reading back from the texture.
Any ideas?

Answered 2021-May-11 at 05:39This is what worked for me:
- Use
sampler2D
instead ofisampler2D
(this seems to be the culprit). - Normalize by multiplying by
32.0
(that is256.0 / 8.0
).
That is:
QUESTION
My problem is that i can't get my textfields with document.getContent()
and document.getContents()
.
So I tried to use XPath for selecting the objects, it works but i can't copy the object and add it again.
For example:
XPath Exception Comment //wps:txbx/w:txbxContent javax.xml.bind.MarshalException SAXException2, Missing @XmlRootElement-Annotation //wps:txbx/w:txbxContent/w:p/w:r javax.xml.transform.TransformerException unexpected Element, because it is on the wrong placeI also tried to make a own object but this also don't worked for me, because it wasn't accepted as an JAXB Object.
This is my code:
...ANSWER
Answered 2021-May-03 at 07:12Probably a namespace issue... The txbx element is in xmlns:v="urn:schemas-microsoft-com:vml" So maybe just change it to: (I don't know how you declare namespaces in docx4j)
QUESTION
I want to create a circle simultaneously by drawing the radius.
The following code draws the radius.
What do I need to add to the code, so that it creates the circle (with no fill etc. just the circumference with a black stroke) simultaneously as the radius is being defined ?
...ANSWER
Answered 2021-May-08 at 09:15I made a few updates to your code for the circle with radius of the current length of the line.
- add a new variable for the circle e.g.
foo
- draw the circle on
mousedown
with radius of 1 (so it is not visible) - you can style with nofill
and blackstroke
etc - in the
mousemove
handler, compute the distance between the origin and the current mouse point (less 1) and make that the radius of the circle.
