'clim:layout-frame called as each letter typed into interactor?
by John Morrison 18 Nov '17

18 Nov '17

Hi; The McCLIM app I am writing has both a pan/zoom application pane and an interactor pane. I am trying to track down why the top-level frame gets resized (radically - too big to fit the X11 screen) when things get drawn onto the canvas. Immediately upon tracing clim:layout-frame, I was surprised to see it (unexpectedly, to me) getting called as each letter it typed into the interactor pane - before I actually start drawing anything (much) onto the canvas/application pane. I am guessing that my output-record-producing drawing similarly triggers the layout protocol again... Is this expected behavior? I was hoping/expecting that the frame layout was computed a "final" time, and then I could draw onto one of its panes with impunity, counting on visible region clipping. If it is not expected behavior, I would be happy to try and track it down. If it is expected behavior, is there some way to prevent it? It is indeed strange for the application to "spontaneously" and dramatically change its size/realization on the screen. Thanks! -jm

dumb question about gadgets
by John Morrison 12 Nov '17

12 Nov '17

Hi; In another app I am writing, I BELIEVE gadgets used to come out stacked vertically. After an upgrade (to current git), I think they come out "diagonally," in that the x & y of successive gadgets increase (presumbly by the dimensions of its preceding gadget). Please find attached the simplest test program I could cons up that displays the behavior, along with a screenshot that shows the behavior. What is the idiomatic/best way to get them to stack vertically? I messed about (again, mostly unsuccessfully, or I wouldn't be pestering you all) with various approaches, but every time I find myself with a complex solution, it turns out there is indeed a Better, Simpler Way. Thanks, -jm

Whoops, didn't reply all. On Nov 11, 2017 13:18, "Lucien P" <drurowin(a)gmail.com> wrote: Have you tried the VERTICALLY macro? To use it as a function call, I believe you make a VBOX pane and set the :CHILDREN to the gadgets, but I'm away from my REPL to get the exact names.

mcclim-based gui prototype for quicklisp
by John Morrison 08 Nov '17

Hi All; https://bitbucket.org/symbolicsimulation/com.symsim.oss.ql-gui Interested in (roughly decreasing order of importance to me): - usability/usefulness - aesthetics (I am not a front end guy in any language) - compatibility with CLIM best practices and idioms (as this is my first CLIM program in decades, or should I say Dynamic Windows?) - compatibility with CL best practices and idioms (as this is my first real Common Lisp program after decades of C/C++, or should I say Zetalisp?) Please be kind, and thanks for all your contributions to McCLIM! -jm
