Re: [Pharo-users] [ Spec ]How can I get input and field with a fixed height?

by Peter UhnÃ¡k

You can say `add:height:` in the layout. You also have to add an empty row at the end that will take the remaining of the space, because otherwise the input fields will fill the window. ``` ui := DynamicComposableModel new. ui instantiateModels: #( gameName TextInputFieldModel platform DropListModel finished CheckBoxModel description TextModel ). layout := SpecColumnLayout composed add: #gameName height: ComposableModel inputTextHeight; add: #platform height: ComposableModel inputTextHeight; add: #finished height: ComposableModel inputTextHeight; add: #description height: ComposableModel inputTextHeight * 4; newRow: [ :r | ]; yourself. ui openWithSpecLayout: layout. ``` Peter On Fri, Sep 29, 2017 at 9:23 PM, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > Hi > > I would like to be able to get combo box, input field with a fixed height. > Any ideas? > > Stef >

Re: [Pharo-users] [Demo] Creating Bloc Widgets with Pharo

by Stephane Ducasse

My suggestion is write tests and after try to build a Spec adapter. The spec adpater will be a really good client. Because with Boc the adapter should not exist at runtime. It should just be there for the registration but not a middle man like now.

But exposing internals of the encoding is not really good either. Graphical objects are complex still forcing all the logic to be set by client is a way to make that we will also get some spaghetti. Look In Morphic at the icon in the menu, we ended up have wrong reference all over the places. Just because the API was not good and did not encapsulate enough behavior.
