Re: [Pharo-dev] Glamour Fast List selection bug or incorrect usage?

by Andrei Chis

Hi, That's actually the default behavior, but I see there is also a bug. Normally if you want to allow deselection in a presentation you should use allowDeselection. Just I see there is a bug in the fast table renderer because if I add #allowDeselection to the first presentation when clicking again on the selected element the selection port is not cleared. If you use #list instead of #fastList it works. I think you can get the desired behaviur using this code: ----------------------------------------------------------------- tabulator := GLMTabulator new. tabulator column: #one; column: #two; column: #three. tabulator transmit to: #one; andShow: [ :composite | composite list allowDeselection; display: [ :x | Array with: x ] ]. tabulator transmit to: #two; andShow: [ :composite | composite list allowDeselection; display: [ :x | Array with: 2 * x ] ]. tabulator transmit from: #one; to: #three; from: #two; to: #three; transformed: [ :x :y | y ifNil: [ x ] ifNotNil: [ y ] ]; andShow: [ :a | a fastList display: [ :x | Array with: x ] ]. tabulator openOn: 4. ----------------------------------------------------------------- Cheers, Andrei On Mon, Apr 3, 2017 at 9:35 PM, Juraj Kubelka <juraj.kubelka(a)icloud.com> wrote: > Hi! > > If you create the following Glamour browser: > > ``` > tabulator := GLMTabulator new. > > tabulator column: #one; column: #two; column: #three. > > tabulator transmit to: #one; andShow: [ :composite | > composite fastList display: [ :x | Array with: x ] ]. > tabulator transmit to: #two; andShow: [ :composite | > composite fastList display: [ :x | Array with: 2 * x ] ]. > > tabulator transmit from: #one; to: #three; andShow: [ :a | > a fastList display: [ :x | Array with: x ] ]. > tabulator transmit from: #two; to: #three; andShow: [ :a | > a fastList display: [ :x | Array with: x ] ]. > > tabulator openOn: 4. > ``` > > You will get the following browser: > > > if you then select 4, the third list appears.

Glamour Fast List selection bug or incorrect usage?

by Juraj Kubelka

Hi! If you create the following Glamour browser: ``` tabulator := GLMTabulator new. tabulator column: #one; column: #two; column: #three. tabulator transmit to: #one; andShow: [ :composite | composite fastList display: [ :x | Array with: x ] ]. tabulator transmit to: #two; andShow: [ :composite | composite fastList display: [ :x | Array with: 2 * x ] ]. tabulator transmit from: #one; to: #three; andShow: [ :a | a fastList display: [ :x | Array with: x ] ]. tabulator transmit from: #two; to: #three; andShow: [ :a | a fastList display: [ :x | Array with: x ] ]. tabulator openOn: 4. ``` You will get the following browser: if you then select 4, the third list appears. If you then select 8, the value is changed: But since then, the third list does not change. It stays with 8 value forever. Do I miss something? Should I define it differently? Or if it is a bug: Can you give me insights how to fix it? Tested in the latest Pharo 6. Thanks! Juraj

ListModel Menu

by Jonathan Khalil

Hello, I am testing the MenuModel and ListModel widgets. I wanted to create a popup menu and then set it with the ListModel >> menu: method. It runs right but once the listmodel open, when i right click on one item to see the pop-up menu it gives me the error as in the "#error.png" picture. Here is my example test (based on not significant data): [ menu := MenuModel new. menu addGroup: [ :group | group addItem: [ :item | item name: 'item1'; icon: (self iconNamed: #nautilus); action: [ anyAction1 ]]]; addGroup: [ :group | group addItem: [ :item | item name: 'item2'; icon: (self iconNamed: #smallSaveAs); action: [ anyAction2 ]]]; addGroup: [ :group | group addItem: [ :item | item name: 'item3'; icon: (self iconNamed: #smallAuthoringTools); action: [ anyAction4 ]]]. ll := LinkedList new. ll add: 'value1'; add: 'value2'; add: 'value3'; add: 'value4'; add: 'value5'; yourself. lm := ListModel new. lm items: ll; title: 'ListModel Menu Test'. *lm menu:menu.* lm openWithSpec. ] I get that the #cull:cull: message is not understood by my instance of MenuModel but i simply call the #menu: method defined in ListModel. Any ideas on the problem ?

Re: [Pharo-dev] the new "fixed" compactor VM has FT broken...

by Peter Uhnak

Thank you Esteban! I've downloaded the latest VM and fonts on cairo now work. I believe this was the last VM crash I am aware of, so hopefully I will have a productive and stable year with Pharo 6. :) (I had some issues with dlls not loading on startup sometimes (mentioned in other thread SurfacePlugin.dll)... but this correlates with some other Windows issues...so I need more info myself).

Estebanâs list of blocking issues for release Pharo 6.0 (updated to April 03)

by Esteban Lorenzano

Hello, This are the things I believe still needs to be solved to be able to release Pharo 6.0: VM: === - win32, cairo fonts problem (I submitted a new VM to test, I think this is fixed :P) - make all tests pass (there are still some failing tests when compiling a new VM)/. - libgit2: Still not there, Jan and Ben were trying and sent some suggestions but I still didnât had the time to test it. Image: ===== - iceberg still needs to go inside the image, Iâm running to release version 0.4 (maybe this week?) and then we can integrate. - I'm still convinced there is a leak. I need to check this in detail. And of course some help on thisâ¦ Pavel?â¦ would be cool :) List is a lot smaller now :) If everything goes well, we can target to release next week. Next: - Test the new process and tape some videos explaining how we will contribute with a bootstrapped process using github :) cheers! Esteban
