Re: [Pharo-dev] evicted zombie process from run queue

by Esteban Lorenzano

you are basically creating 1000 * 100000 morphs (and complex ones). I would just do a matrix morph with just one morph and rendering the matrix in the canvas (overriding the #drawOn:) BTW, I do not think VW would work like that either: IMO, that design (pre-generating the cells) is bad and it never works. Other frameworks use a datasource design (like cocoa, swtâ¦ and basically all the serious frameworks I know about). and no, we do not have a default design for this kind of big components (a serious absence, IMO).

Why not? Do you know a better grid morph? I have tested several ones but there is no way to visualize big matrices in Pharo (I am avoiding to switch to VisualWorks for now).

he, you are trying to open a tree with 1000 columns and 10000 rows. that will never work, not like that.

Hi Christophe, Thanks for the answer. I managed to do that! Am I interpreting something wrong or the CoolBrowser-Platform itself is an empty package?
