I have written an image viewer that uses FLTK-1.3 . On MS-WINDOWS (Win7) the origin of the image window is fixed at the current position and the image window height and/or width changes with the width and height of the image.
On LINUX I use fvwm 2.6.5 . With LINUX I have a severe problem: the image window hops around like a frog when the image window height and width changes with the width and height of the image. I have sent an EMAIL to the list https://groups.google.com/forum/#!forum/fltkgeneral and asked what I can do: >> This does not fix the window at the (x,y) position and the window >> hops around like a frog when the width/height of the still image >> changes. > >That's odd. >Seems to work OK for me (testing on F17 and ubuntu-13.10) - >what does the resize demo form the test folder do?

I have made a test. I have compiled and installed XFCE-4.10 and found, that the image viewer shows the same stable behaviour as with MS-WINDOWS: the window origin remains fixed while the width and/or height of the image viewer changes. Is it possible to configure FVWM such that the origin of the FLTK window does not change? winfried
