Windows 10: GNVM window does not snap to sides of screen (and is not affected by PowerToys zones)

[rabirabirara]

I am on Windows 10.

There is a Windows feature called Snap where dragging a window to the side of the screen will resize and snap it to the right half of the screen. This doesn't work on the Goneovim window, nor does it work using the hotkeys "Win + Left/Right Arrow". (Win + Up/Down Arrow work presumably because those are maximize and minimize respectively, which are obvious functions.)

I also use PowerToys to do primitive tiling. On a typical config, clicking and dragging a window and then right-clicking while holding the click will allow you to snap the window to a certain zone; the Goneovim window is incapable of this too. Even when I use the SHIFT key to trigger the snapping instead of right-click, the snap zones do not show up.

Furthermore, in trying that, I discovered that the window's title bar cannot be right-clicked; any right click acts like a left click. Same for middle click. I wonder if this is intentional?

Expected behavior: I can snap the window like any other. Or, I can right-click the window's title bar.

@rabirabirara Hi, thanks for this issue.

Please let me know your goenovim version:GonvimVersion, the contents of your settings.toml, and the version of your Windows OS (the result of systeminfo command is best) so I can investigate.

On my PC goneovim v0.5.1-87-gaa788ad works on Windows10.

Goneovim version: 0.5.1

OS version, from systeminfo:

OS Name:                   Microsoft Windows 10 Home
OS Version:                10.0.19044 N/A Build 19044

My settings.toml file is literally just the default file with some things commented out.

## Goneovim settings.toml
## All of the following commented configuration items have default values.

[Editor]
## Makes the application window frameless.
# BorderlessWindow = false

## Editor minimum window width (>= 400)
# Width = 800
## Editor minimum window height (>= 300)
# Height = 600
## Create a small margin on the left and right sides of the application window.
# Gap = 2

## Specifies the command used to open the file in an external file explorer, etc. The default is ":e".
# FileOpenCmd = ":e"

## Reverses the direction of scrolling with the mouse wheel.
# ReversingScrollDirection = false

## Specifies the amount of scrolling by the mouse wheel. The default value is 1.
# LineToScroll = 1

## This option makes the whole GUI window in semi-transparent.
## This setting also implicitly enables the Drawborder setting
Transparent = 0.95

## Launch goneovim with full screen window size.
# StartFullscreen = false

## Editor external font-family, font-size, and linespace.
## This is the font and linespace settings of the graphical UI as an nvim front end.
## For example, linespace affects the margins of the external completion popup menu UI.
## Note that the linespace setting must be the same on the Neovim side. The reason for this
## is that the default value on the Neovim side is 0, which will be overwritten by the Neovim setting.
## Of course, these settings can also be changed by setting the guifont and linespace on the Neovim side.
## Fontfamily is
## In MacOS, 
# FontFamily = "Monaco"
## In Linux
# FontFamily = "Consolas"
## In Windows
FontFamily = "Hack Nerd Font Mono"
## Fontsize is
FontSize = 10
## linespace is
# Linespace = 6

## Neovim external UI features
## The following is the default value of goneovim.
## You can change the behavior of the GUI by changing the following boolean values.
## If you prefer the traditional Vim UI, set it to false for all.
## Also, `ExtMessages` is still experimental at this time and we don't recommend setting it to true if you want stability.
# ExtCmdline   = false
# ExtPopupmenu = false
# ExtTabline   = false
# ExtMessages  = false

## Goneovim has a cached rendering feature enabled to speed up the process.
## If you want to disable it, set it to false
# CachedDrawing = true
## You can specify the cache size to be used by the cache rendering feature of goneovim.
## The default is 400.
# CacheSize = 400

## Disables font ligatures.
# DisableLigatures = true

## Copy yanked text to clipboard
# Clipboard = true

## This setting is equivalent to Macmeta in MacVim.
# Macmeta = false

## The input method editor will be automatically disabled when the mode is changed to normal mode.
## It may be useful for users who use the input method editor (e.g. East Asian users).
## DisableImeInNormal = false

## Draw borders on the GUI side instead of the vertical border and status line that nvim draws.
# DrawWindowSeparator = false
# WindowSeparatorTheme = "dark"
# WindowSeparatorColor = "#2222ff"
# WindowSeparatorGradient = false

## Draw built-in indent guide
## Enabling this setting will have a slight impact on performance.
# IndentGuide = false
# IndentGuideIgnoreFtList = ["md"]
# OptionsToUseGuideWidth = "tabstop"

## Animates the scrolling behavior of Neovim when the scroll command is entered.
# SmoothScroll = false
## Disables horizontal scrolling for smooth scrolling with the touchpad.
# DisableHorizontalScroll = true

## Draw border on a float window
# DrawBorderForFloatWindow = false

## Draw shadow under a float window
# DrawShadowForFloatWindow = false

## Enable desktop notification settings for nvim messages.
## This option works only if `ExtMessages` is enabled.
# DesktopNotifications = false

# Display the effect when clicked
# ClickEffect = false

# Pattern that fills the diff background
# Change the background pattern used for diff display.
# This option allows you to use a visual effect pattern such as Dense, Diagonal Stripe instead of a regular solid pattern.
# The available patterns are all Qt brush styles. For more information, See: https://doc.qt.io/qt-5/qbrush.html#details
# // -- diffpattern enum --

## You can write a vimscript to be executed after goneovim starts,
## for example to disable the vimscript that Goneovim has embedded internally.
## GinitVim = '''
##  let g:hoge = 'fuga'
## '''
# Ginitvim = ""

[Cursor]
## Specifies whether the smooth cursor feature is enabled or disabled by a boolean value.

As a bonus reference, this is what the goneovim titlebar looks like for me; perhaps that can give a clue.

@rabirabirara That is weird. The screenshot you have posted is what it looks like when borderlesswindow are true. Indeed, goneovim has its own window control when borderless windows mode. The window snap should be controlled to be effective, but there may be an edge case that is not working properly somehow. But looking at your settings, borderlesswindow is not true, so goneovim should be of normal window appearance(it is exactly what @shiena posted)

[Glirastes]

@rabirabirara @akiyosi I am experiencing the same issue. I have found, that this gets triggered by the transparency setting: if it is set to 1.0, I get a normal window with border that is maximizable, minimizable etc. However if the value is lower than that, I always get a borderless window that exposes exactly the behaviour described in this issue. If additionally StartMaximizedWindow = true, then the borderless window is also missing the maximize button.

[akiyosi]

@Glirastes Currently on Windows, the behavior is as you described above. That is

• If boderlesswindow = true and transparency = 1.0, window snapping is enabled.
• If transparency < 1.0 (in which case boderlesswindow = true implicitly), window snapping is disabled.

I currently have no ideas on how to implement this in such a way that the window content remains opaque but the window is transparent and the window snapping feature is enabled.
