react hooks setState lagging one step behind

Asked 2020-Jul-20 at 12:26

I have this checkbox input, when i click on it, i take its value and add to state array called vendorFilters but seems like state is always 1 step behind, i was using class component i thought switching to hooks might solve the problem but it did not.

I have attached codesandbox link, kindly have a look.

setState is an asynchronous function and it needs some time to update the state. It is not instantaneous. This is because setState alters the state and causes rerendering. This can be an expensive operation and making it synchronous might leave the browser unresponsive. Thus the setState calls are asynchronous as well as batched for better UI experience and performance.

Fortunately, setState takes a callback:

Create widget with transparent hole inside

Asked 2020-Feb-23 at 00:25

The "easiest" way I've found to do it is using a ColorFiltered Widget with a Stack.

When altering the number of checkboxes being provided, the ModelState maintained a list of previous checkboxes. Clearing the ModelState has resolved the immediate issue. I'll look into manipulation of the ModelState if necessary but clearing seems to be the way to go. I just have to reapply checks that were used previously to build out the new checkbox lists.

Emit signal from QAction passing custom widget value

Asked 2018-Jun-04 at 21:12

I have created a simple menu using a custom widget. How can i make the menu QAction emit the color value of the swatch clicked? Each color swatch contains a property called 'color'. If the user clicks 'Reset' i would like the value emitted to be 'None'

I tried to overload the triggered signal to pass the color of the swatch clicked but it didn't work either.

Answered 2018-Jun-04 at 21:12

Instead of trying to use the triggered signal it creates a new signal that sends that information. Also you should know that a signal can also connect to another signal as I show below.

Problem is solved by changing parmission of wireshark files located at /usr/local/share/wireshark.

Now from non-root user I'm able to run wireshark without any error popup. :)

How to change imageview content between color and image programmatically?

Asked 2017-Mar-24 at 19:19

I'm trying to create a program where when i click on an image view i switch the content of it between a color and an image. I tried this 2 controls: setBackgroundCOlor and setColorFilter but if the imageview is already showing an image the first one will set the color of a layer behind the image, and the second one will color all the image with that color, so the next times i will not see the image anymore.

I used this code lines:
