    Resize Listview

    Hi,

    I have a realizable window with a list view in it. When the window resizes, I'd like to resize it as well. Is there an automatic way to do this, or do I have to do it manually? Thanks.

    That depends on the programming language. In Delphi for example, you could set design-time Anchor attributes and it would happen automatically at runtime.

    I create the listview as a ratio of the window size (ie 90% height, 30% width)

    I process WM_SIZE (OnSize) msgs and call SetWindowPos() with the new ratio.

    Some owner draw can cause issues with this though, in which case I destroy the listview and create a new one.

    So how do you set up the window as a ratio? Or are you just saying you look at it and set it that way? Also, how do you know how much to change it? Does the WM_SIZE message contain the amount of change?

    I decide at design time how big the controls need to be to look good and fit the data. I adjust the controls ratio (percentage) accordingly and hard code it. I get the ratio by trial and error (looking at it).

    The WM_SIZE contains the new width and height of the window.

    I calc the controls new width and height using the ratio and the new size. Then use SetWindowPos() to change the size of the control.

    I do not need the 'amount' of change, just the new width and height.

    This also ensures that my app looks proportional at any resolution and window size.
