Draw lines of code to stick to Chou Chou?
I first thought is finished first invalidaterect update to specify the content of the cell to clear across the line

Grid line drawing, and then draw the scarlet letter, only can

Attachment code, when performing to the current case, the corresponding grid connected on a line, so can't draw the line, even frame again

CodePudding user response:

Can be finished, then simply draw a grid

CodePudding user response:

It will take a lot of judgment?

CodePudding user response:

reference 5 floor zmingits reply:

it will take a lot of judgment?

The same since the draw function drawall (NoLine: Boolean), by a Boolean variable to determine whether line painting
The original function is changed to:
Drawall (true);
Drawall (false);

CodePudding user response:

Thank you, still don't understand.

CodePudding user response:

refer to 7th floor zmingits response:

thank you, still don't understand.

Put your original XXX since the draw function transformation, increase a parameter NoLine: Boolean
Inside painting lines of code, instead of all to decide whether to execute by NoLine

The original painting is XXX (false);

The requirements of the new painting is
XXX (false);
XXX (true);
