trees in Glamour
Locked
 
|
Hello,
I am constructing a tree presentation with Glamour. Parents are modules in my tree and children are a module's functions. Here is the code: modulesIn: composite
^ composite tree title: 'All Modules'; showOnly: 50;
display: [ :each | each allModules]; tags: [ :each | {each numberOfFunctions asString} ];
format: [ :each | each mooseName]; selectionAct: [:each | each selection inspect ] on: $i entitled: 'Inspect';
icon: #mooseIcon; children: [:each | each functions ]. Now, when I click on a child, glamour wants to executes the children and tags block on a function in the above code. Now since my functions do not understand the messages functions/numberOfFunctions, there is an error.
My question: for constructing a glamour tree, should parents and children both understand the same API or am I missing something here? thanx Usman

Hi,
The children block is applied to every child. So, naturally, it has to work on every child :). So, one possibility to describe your situation would be like: children: [:each | each isModule ifTrue: [each functions] ifFalse: [#()]] Another possibility would be to define the elements by level. There is a default variable on the last position in the block that holds the level of the current child. Please take a look at GLMBasicExamples>>treeWithChildrenByLevel.
