问题
I'm trying to improve a plotting library that I wrote with GtkD (the D bindings for Gtk). Scatter plots with a lot of points take a long time to resize. I want to rescale the image, allowing pixelation, while the user is dragging the window edge to resize, and only re-render it when the mouse button is released.
Is there an API to detect whether the user is still holding down the mouse button to drag the window edge when a window is being resized? If you are not familiar with GtkD, a response in terms of the C Gtk API would still be appreciated.
回答1:
you can add a 500 millisecond timeout to the redraw (resetting the timer on each resize event) this allows a user to see a preview while dragging
