Re: [Pharo-users] How can a Morph display a context menu on a mouse click?

Thanks to all answers! It finally works. :-) 
I am not sure where I did a mistake before.

And your original question

morph := 'Hello' asMorph.
colorBlock := [ :colorName |
  morph color: (Color perform: colorName)].
morph on: #mouseUp send: value to: [ |menu|
  menu := MenuMorph new.
  menu add: 'orange' target: colorBlock selector: #value: argument:
#orange.
  menu add: 'blue' target: colorBlock selector: #value: argument:
#blue.
  menu popUpInWorld].
morph openInWindow

Works fine for me in Pharo 7.

You do click, do you ?

Her is a variation:

morph := 'Click me' asMorph.
morph on: #mouseUp send: #value to: [ self inform: 'You clicked me!' ].
morph openInWindow.

Well, it works for me on 60528 on Windows. Did you open the transcript
window before running the example?

I am not sure if we understand each other. 
The example: 

morph := 'Hello' asMorph.
morph on: #mouseUp send: #traceCr: to: morph.
morph openInWindow

does not work for me. Actually I have not found a code that triggers #mouseUp 
event neither.

The example:

morph := 'Hello' asMorph.
morph eventHandler: MorphicEventHandler new.
morph eventHandler
on: #click send: #traceCr: to: morph.
morph openInWindow.

works well and this is what I use.

All tested on Pharo 6.1. 

Cheers,
Juraj

Not at all? Or do you just need to use the variant sending #value: to a
block with the morph as an argument?

This does not work for me either. 
I am fine with the MorphicEventHandler solution.

Thanks!

There is my exercise:

“when:send:to"
morph := 'Hello' asMorph.
morph when: #click send: #traceCr: to: morph.
morph openInWindow.


Sorry

morph := 'Hello' asMorph.
morph on: #mouseUp send: #traceCr: to: morph.
morph openInWindow.

Thank you Stephan!

There is my exercise: 

“when:send:to"
morph := 'Hello' asMorph.
morph when: #click send: #traceCr: to: morph.
morph openInWindow.

—> it does not work for me. I do not know what the announcement should be

"Handler"
morph := 'Hello' asMorph.
morph eventHandler: MorphicEventHandler new.
morph eventHandler
on: #click send: #traceCr: to: morph.
morph openInWindow.

Thanks!

[Pharo-users] How can a Morph display a context menu on a mouse click?

[Juraj Kubelka]

Hi, 

Let’s say that we have a StringMorph: ‘Hello' asMorph.
Can I attach a MenuMorph (or a menu building logic) and display the context 
menu on a mouse click in the StringMorph? 

Or the only way to do it is to subclass the StringMorph and write the logic in 
the #mouseDown: method? 

Thanks!
Juraj
