Hi! Why do you need to profile fast code? You can always put your code in a loop.

To profile the creation and drawing, create a canvas and do a #fullDrawOn: onto it. Example: [ | morph canvas | morph := FTTableMorph new extent: 300@300; dataSource: (FTExampleDataSource elements: (Smalltalk allClassesAndTraits sorted: [ :a :b | a name < b name])); yourself. canvas := FormCanvas extent: morph fullBounds extent depth: Display depth. morph fullDrawOn: canvas ] timeProfile.

Inspect the morph and do: [ self fullDrawOn: Display getCanvas ] timeProfile If it is a FT-based morph, you may have to do a self refresh or self changed, so that you can measure the recreation of the submorphs. Normal GUI code has very short rendering time (a few tens of milliseconds), except when you use large fonts and sub-pixel rendering (LCD setting on FreeType rendering).

Re: [Pharo-users] About profiling code

by Guillermo Polito

Out of the top of my head, doing it like that only profiles widget creation/install if I'm not mistaken. But not render time. Because the doit is executed inside the event processing of the morphic render loop. But a cool ui profiling should also measure the drawOn: methods. I don't know if there is a tool to do that right know but it would be possible...

yeah probably , your code returns nothing too. So what we suppose to use to profile fast code ?

About profiling code

by Dimitris Chloupis

Why [CheckboxMorph new] timeProfile returns nothing ? I also tried it in the profile tool without the block and still displays nothing . Is there any special requirement for profiling code ?
