Preventing Grid from resizing when the item height is increased

Question

I created a grid of size 200,200 and placed a button in it of size 200×200.

Grid[{{Button["Button", Null, ImageSize -> {200, 200}]}}, 
       Background -> Red, ItemSize -> {15, 15}, 
       Alignment -> {Center, Center}, Frame -> True]

When I tried increasing the width of the button, the edges on the 2 sides didn't appear as expected, but when I increased the height of the button, the grid itself gets enlarged to the button's height. I don't want this enlargement to happen. How can I avoid it?

Answer 1

As the comments suggest, one could use Pane surrounding the Button, but then the alignment doesn't work correctly if the button is too large. So instead I'd use Framed because you don't seem to want the ability to resize the content, just crop it when it's too large:

Grid[{{Framed[Button["Button", Null, ImageSize -> {200, 300}], 
    ImageSize -> {210, 210}, Alignment -> {Center, Center}, 
    FrameMargins -> 0, FrameStyle -> None]}}, Background -> Red, 
 Alignment -> {Center, Center}, Frame -> True]

To make this work, I had to specify the size of the item with an explicit ImageSize in Framed, instead of the ItemSize option in Grid. Here the button has been resized to be too large in the vertical direction, and you see that it's still centered but cropped at the top and bottom without changing the cell size.

The alternative of using Pane is especially useful if your plan is to have the content automatically resize to fit the fixed box, because Pane has the option ImageSizeAction -> "ResizeToFit", while Framed doesn't allow that.
