Pharo IDE - change mouse cursor color/size

Hi there,

I'm not able to find any setting in the Pharo IDE related to changing the
mouse cursor color or size?
Can this be done at all? Thanks in advance.

Re: Pharo IDE - change mouse cursor color/size

If you are on Windows you can load Vista cursors from the catalog. Then you will have settings for the size.

Not all cursors are implemented but it is easy to do.

On Linux I had VM crashes when doing #beCursor. Maybe is it fixed these days.

Hi phil

Yes we want to kill all the VM logic related to events because IT GETS
ON OUR NERVES.
Kill them all. Esteban told me that he is super upset by all the event
/ screen logic and that he is looking at ronie' changes.

VistaCursors worked great on windows. It also led me to the discovery of the
Cursor class, the different cursor types (normal, resizing, etc.) and masks.
Thank you for your help.

PS: I also found out how to register custom settings to be added to the
Settings dialog. That will come in handy at some point I'm sure.

Re: Pharo IDE - change mouse cursor color/size

@Phil: Maybe because I wrote the package back when I was on "Vista" and you should not
use on Linux ;)

To be serious: Yes - changing the cursor in Linux never worked (for me). And the windows
VM had large cursor introduced as "experimental" in 2009:

http://forum.world.st/squeak-dev-New-Window-VM-Closures-FT2Plugin-Large-Cursors-td81092.html

Agree that more parts should be moved to image, especially window and key event related things. But this
is on the list since years - so the basic question is more if Estebans has the time to work on it.

Cursor>>beCursor with Cursor being a Form makes a lot of sense on any platform.

On this age of Hi DPI I can't live with a tiny cursor that I cannot spot.

And we should basically be able to have massive cursors with animations etc.

Event logic should be in the image indeed. The current system is a tad convoluted and one needs a couple of mental hops for understanding what comes from where.

Also, this will maybe allow for cleaner stopping of runaway loops.

There is a chapter in Deep into Pharo on Settings.

He is working on it.

He is just losing time on trying to recompile plugins on windows and
other time consuming and ugly tasks.
We should move as much as we can to FFI because some plugins are hell
to maintain.

Could you be more explicit?

If beDisplay makes sense for DisplayScreen why not beCursor for Cursor?
While a Cursor can be emulated in an image, it would be more efficient
to use the cursor support present in practically all graphics
controllers these days.

I guess because a cursor and a display are already cursors and displays (hence the “be” does not has sense), when what you are trying to do is actually to “install” them or “use” them, or “activating” them :)

There is no such thing at the moment in Pharo (maybe OSWindow is different).

* Windows cursor is not reflected in the system, it is a black little arrow by default.

* macOS cursor is not reflected either. I can set it as large as I want it doesn't agrees to.

* Linux. Black thing and changing to a larger form makes Pharo crash.

beCursor makes sense when used like this:

setMoveCursor

|form cursor|

form := (Form

extent: 23@23

depth: 32

offset: 0@0).

form := form magnifyBy: VistaCursorSettings cursorScaleFactor.

cursor := Cursor extent: form extent depth: 32.

cursor offset: (form width // 2) negated @ (form height // 2) negated.

cursor bits: form bits.

Cursor classPool at: #MoveCursor put: cursor.

cursor beCursor

And we could load that thing from a PNG or a web resource etc.

Until beCursor is not sent, the Cursor is not really *the* hand cursor.

I actually like the beXXX way. It makes a lot of code clearer, especially when cascading options for a given object.

We used to have the ability to have several "hands" active at once in an image (actually I miss that).

I guess that for such scenarios, a system cursor is not going to be of much use.

But I want to have the ability to reflect the system cursor in Pharo so that it doesn't look too alien or "ugly" when it comes to cursors.

I guess because a cursor and a display are already cursors and displays (hence the “be” does not has sense), when what you are trying to do is actually to “install” them or “use” them, or “activating” them :)

Nah they are not. Installing would be a shortcut for e.g. Cursor classPool at: #MoveCursor put: cursor.

activate? Well, there is already

showWaitCursorWhile: aBlock

Cursor wait showWhile: aBlock

So that we can do UIManager default showWaitCursorWhile: [ 10 seconds wait ]

doing

Cursor wait showWhile: aBlock

Then we get

Cursor wait showWhile: aBlock

So that is not activate nor anything.

And we can also need to use something from the hand.

ActiveHand showTemporaryCursor: Cursor resizeBottom.

There are quite several use cases beyond "activating" a cursor.

If I added -lXrender to LIBS and -DHAVE_LIBXRENDER=1 to CFLAGS into
mvm, so for exammple in
opensmalltalk-vm/build.linux32x86/pharo.cog.spur/build.debug

CFLAGS="$OPT -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DCOGMTVM=0
-DHAVE_LIBXRENDER=1" \

then I was able to make beCursor primitive work on Ubuntu, see the screenshot

Sorry but Cursor>>beCursor does not make any sense on any platform :P
Could you be more explicit?

If beDisplay makes sense for DisplayScreen why not beCursor for Cursor? While a Cursor can be emulated in an image, it would be more efficient to use the cursor support present in practically all graphics controllers these days.

I guess because a cursor and a display are already cursors and displays (hence the “be” does not has sense), when what you are trying to do is actually to “install” them or “use” them, or “activating” them :)

Exactly. beXXX is used to make something adjust. A cursor is a cursor. So it needs to be called at least beXXXCursor where XXX gives the context what actually do, be it installation somewhere or… as Esteban said make that useXXX
