This sounds like mixing the features from: - http://docs.factorcode.org/content/article-embedding.html which initializes everything, but then requires the compiler to use a string - factor eval - string call. - http://docs.factorcode.org/content/article-alien-callback.html which allows to directly

Re: [Factor-talk] Model activation sequence

Hi Mark, I'm basing my remarks on https://github.com/hyphz/fr8x-editor/tree/257e244c3a20175a5c88d8c2f776999897025776 Like you said, for the arrow to work, it needs to be activated. In your program the activation of the arrow is done by the open-window which calls the graft method of the checkbox

Actually, the call to activate-model is just before the call to the gadget's graft* method, but the point remains the same Jon On Sat, Jan 3, 2015 at 8:02 PM, Jon Harper jon.harpe...@gmail.com wrote: Hi Mark, I'm basing my remarks on https://github.com/hyphz/fr8x-editor/tree

Re: [Factor-talk] Dealing with parts of a model

Hi Mark, model-field can't work with arrows. Among other reasons, in your case the arrow is not activated when it's data is used to intialize the editor string (that's why you see them empty). The model given to model-field isn't meant to be updated by the caller anyway: it's value is used as an

Re: [Factor-talk] how to calculate count of days

Georg's problem comes from the fact that ymdtimestamp represents a date by midnight gmt, whereas today represents it by midnight in the local timezone. The API should make it clear how we represent dates (ie whole days, which are not even the same 24 hours in different time zones) with timestamp
