Description:
The QLedMatrix widget simulates a LED matrix (dot matrix) display.
A LED matrix display is a 2-dimensional array of dots used to generate characters, symbols and images. It is often seen on machines, clocks and display boards.
This generic implementation can configured for any size of rows (greater than 0) and columns. The number of colors is not limited, therefore it can be used to make a monochrome, bi-color or even a full RGB display.
Individual LEDs can be addressed in the matrix by their row and column position. The index (0,0) is located in the upper left corner. Columns grow from left to right, and rows grow from top to bottom. Last changelog:
