QUESTION
I used monaco editor's OverlayWidget and Viewzone api to insert a inline text in monaco editor like the monaco editor example https://microsoft.github.io/monaco-editor/playground.html#interacting-with-the-editor-listening-to-mouse-events.
but when I changed the OverlayWidget's height, the Viewzone's height was not changed.
I tried use layoutZone api to reset viewzone's height, but It seemed not work.
...ANSWER
Answered 2021-Mar-26 at 01:55I solved this problem。
yes, accessor.layoutZone(viewZoneId); will reRender the viewzone.
the key is use a getter method of viewzone's heightInPx property like below;
QUESTION
I want to move the mouse in a certain position (0,0). After a previous click action I need in fact to move away the mouse from that position, as it's interfering with the next action I need to do.
I've found following Java code which is a perfect starting point but I'm not able to translate it into VBA and to adapt to my need.

QUESTION
I'm editing this question because I think I may have oversimplified the way in which my status item's menu opens. It's ridiculously complicated for such a simple function!
My status item supports both left and right click actions. The user can change what happens which each click type. Also, due to a macOS bug, I have to do some extra-special work when there are 2 or more screens/displays connected and they are arranged vertically.
I’m using MASShortcut to open an NSStatusItem's menu via a system-wide hot key ("⌘ ⌥ M", let's say), and I'm finding that once the menu has been opened, it's not possible to close it with a hot key. I'm trying to toggle the menu from closed to open and vice versa. When the menu is open, code execution is blocked, however. Are there any ways around this? I found this question which seems like a similar issue, but sadly no answer was ever found.
Thanks in advance for any assistance!
UPDATE: Sample Project Demonstrating Issue
When the user executes the designated hot key to show the status item menu, the following runs:
...ANSWER
Answered 2021-Feb-26 at 19:27I can confirm your observation
I'm trying to toggle the menu from closed to open and vice versa. When the menu is open, code execution is blocked
The reason is NSMenu
when opened takes over the app's NSEvent
s handling (it's internal __NSHLTBMenuEventProc
handles that) over the standard [NSApplication run]
queue.
The events that will actually trigger the shortcut handling eventually are NSEventTypeSystemDefined
with subtype 6 (9 being the following keyUp which aren't really relevant here).
Those NSEventTypeSystemDefined
aren't fired at all when the menu is opened. Some mechanism is postponing their firing until the menu is dismissed and the app gets back to [NSApplication run]
queue. A tried a lot of tricks and hacks to circumvent that, but to no avail.
MASShortcut uses legacy Carbon API to install this custom event handler. I was able to plug it in instead to the NSMenu internal Event Dispatcher (it works when the menu is not opened) but it doesn't solve the problem because the aforementioned NSEvent
s weren't fired in the first place (until the menu dismisses).
My educated guess is it's the MacOS WindowServer that's governing this (since it's aware of things like control keys pressed among others).
Anyway I'm glad you've found your workaround.
If anyone would like debug those events (I guess this is the best starting point I can offer) here's the code I used:

QUESTION
I want to position a pop-up element directly below the text caret/blinking text cursor in a textarea or content editable element.
I've found answers that give me the text index within an element where the caret exists, but as far as I can tell this is useless to me. (like this)
I need something similar to the event.pageX and pageY properties available with mouse-events, but I want that same thing for the position of my text editor caret. Anyone know how to do this?
...ANSWER
Answered 2020-Sep-06 at 23:02You can't get the exact coordinates of the text caret effortlessly, but this snippet will give you a rect
object with the approximate coordinates of the window's current selection. You may have to also add/subtract use additional offsets of containing elements depending on your styling.
QUESTION
I'm trying to change page in a PageView when the mouse scrolls,
I'm using a Listener following this article,
in my implementation (https://dartpad.dartlang.org/c2b24881927981575ff81367121f4e5f)
using the fabs it behave as expected:
- move to the new page
- print the new page number
then
prints eithernext
orprevious
page
but the callback in the Listener
behave weirdly :
- print the message from the callback
- does NOT move to a new page
- but
then
prints eithernext
orprevious
page
I'm not sure what is the cause of this behavior, any idea? Thank you

QUESTION
Note: The question here is specifically for the case of Matlab!
The context of this question is a Matlab handle class, which receives some data over a websocket, does some processing to that data and then forwards the data to some other classes, which registered themselves with callbacks.
A simplified version of this class is given below:
...ANSWER
Answered 2020-Jul-10 at 11:38As always, it depends on your use case.
Personally, I think the main advantage of using events is that you could have multiple listeners triggered by the single event (with no additional coding for you, see here for an example: https://mathworks.com/matlabcentral/answers/13305-can-timers-trigger-a-single-event-that-many-objects-listen-to).
It also allows you to have callbacks with potentially different argument lists, whereas in your example the callback function must take only one argument, the data.
With regards to execution order (https://de.mathworks.com/help/matlab/matlab_oop/callback-execution.html#bu0b2f4):
The order in which listeners callback functions execute after the firing of an event is undefined. However, all listener callbacks execute synchronously with the event firing.
QUESTION
So I have been looking for multiple ways to perform a "click" without actually moving the mouse. After hours of searching, I came upon these two pages: ctypes mouse_events and https://schurpf.com/python-mouse-control/ where there's some code that can apparently perform a click without moving the mouse. The code seems to come from the same person, but https://schurpf.com/python-mouse-control/ seems more up to date with the "Added functions". I tried fixing it for a while but didn't get anywhere and am stuck with the following script
