Re: [Pharo-users] Spec - Grid/Table Layout

In the example I gave with TreeColumn/MorphTreeColumn the block used to render the item can return anything understanding #asMorph. So you can easily return any Morph you like there :) Ben On 08 Nov 2013, at 12:18, prova email <prova213(a)hotmail.it> wrote: > Hi Clement; > > I did the Spec tuto made by Bahman (great tuto).

Hi Clement; I did the Spec tuto made by Bahman (great tuto). As him, i'd like to put some widgets into it. Is it possible? Maybe with the method "items:"? I don't know if the solution that Ben give to us (use Morphic instead of Spec) is suitable, that's because his UI looks like a list that accept only string.

Re: [Pharo-users] Spec - Nested Layouts

by Benjamin

I have two arguments: - there are multiple arguments for TreeColumn and writing down all the combination will result in a lot of method, uselessly polluting the API - you lose the ability to modify the column on the fly since you do not have a pointer to it. But anyway, I think I will introduce a TableModel, because even if you can tweak a TreeModel to act as a Table it is not obvious, and not really expected from a Tree :) Ben On 08 Nov 2013, at 00:06, btc(a)openinworld.com wrote: > Don;t have time to try it till later today, but first thoughts... > > What do you think about usage something like... > > tree header: > {'Name' .

Re: [Pharo-users] Why won't my Pharo download run?

Well, it does run on my second (and even older) machine with an Intel Celeron processor. I have in store a very old download of Pharo (version 1.1, dated July 2010), which I have loaded and run successfully on the troublesome machine. I shall probably have to give up on this machine and switch to my reserve, unless anyone has a brilliant idea to fix it.

I presume all versions now use the Cog VM, and it looks as though this machine just won't run it. Is there still a 'traditional' VM I can use instead of Cog?

This loads successfully when I double click on pharo.exe. On the other machine, the same action produces an immediate message: 'Pharo.exe has encountered a problem and needs to close'. Just in case this was some problem with Moose, I have just downloaded the latest one-click installation of Pharo 2.0 for Windows. This displays exactly the same behaviour - an immediate fail when I try to start it. I have tried to work out what may be different between the two machines. The one which will run Pharo has an Intel Celeron processor, the other an AMD Athlon XP (yes, they are both pretty ancient!), but I can't see why that should make any difference. The one curious thing is that Windows Explorer displays the type of the Pharo2.0.image file as 'Squeak image file'. There is an old version of Squeak installed on that machine; could that have any effect? I am a bit flummoxed by all this. Does anyone have any suggestions about how to diagnose the problem? If you using too old VM , it simply does not supports an image format, which pharo 2.0 uses. But there could be different reasons.. a first step towards to solution is to use VM for pharo, which we maintain and use..

Re: [Pharo-users] Spec - Nested Layouts

Don;t have time to try it till later today, but first thoughts... What do you think about usage something like... tree header: {'Name' . 'Last Name' . 'Age' . 'Gender' }; roots: { {'Benjamin'.'Van Ryseghem'.'26'.'M'}. {'Pamela'.'Anderson'.'Far too much'.'F'} }; displaySymbolOrBlocks: { #asString . #asString . [:node|node asString] . [:node|node asString asUpperCase ] }. Or... tree columns: { 'Name' -> #asString. 'Last Name' -> #asString. 'Age' -> [:node|node asString]. 'Gender' -> [:node|ndoe asString asUpperCase ] }; roots: { {'Benjamin'.'Van Ryseghem'.'26'.'M'}. {'Pamela'.'Anderson'.'Far too much'.'F'} }. Ah, the danger of contrived example. So actually now I think on it, that is not so flexible as your example. Maybe then just hiding TreeColumnModel using... tree withColumn: 'Name' display: [:node | node content first asString ]; withColumn: 'LastName' display: [:node | node content second asString ]; withColumn: 'Age' display: #third; "is there a use case that would not always use 'node content' ?
