Vote count: 0 I am trying to draw a custom popup menu on MFC single-document interface (SDI) project.From here, I found The framework calls this member function for the owner of an owner-draw button control, combo-box control, list-box control, or menu when a visual aspect of the control or menu has changed.So I added the handle OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct) and added some code inside this function, but I found that this callback didn't be called by the framework when I right click on the view, like this:How to make a popup menu dynamically? asked 1 min agosflee Let's block ads!...

Vote count: 0 So I want to draw a 2D image using OpenGL ES of some shape by drawing one big triangle and then draw additional triangles that go over this triangle such that they cutout the big triangle and result in the desired shape. I'm not sure where to define these additional objects: Do I define them within the class of the original object or do I create new classes for each object?

Vote count: 0 I have an n*2 matrix (n is even), and regard each row as a point in the R^2 Euclidean Space. I can use the plot command in R to plot each row vector. Then I generate another n/2*2 matrix, in which each row contains two integers between 1 and n, which index the rows for the two points in the matrix I just plotted. However, if I want to draw a line between row vector in the n*2 matrix according to the rows in the newly established n/2*2 matrix, what command in R should I use? (For example, if the 1st row for the n/2*2 matrix is (1,3), I should draw a line coecting the 1st and 3rd row(point) in the n*2 matrix.)
