There currently seems to be no way in Krita to disable the Popup Palette without loosing the popup dialog functionality on the canvas for other tools, for example the transform or the selection tools.
This is especially annoying since the selection tool popup contains menu actions that are usually only accessible inside nested submenus in the window menu bar.
With some further investigation I found out that the “Show Popup Palette” setting got merged into a global “Show Popup Widget” setting starting with Krita 5.0.
I found a lot of people asking “how to disable the Popup Palette” in various forums and the answer is always that all popup widgets on the canvas can only disabled completely. This is obviously not what most users actually want.
It’s probably not necessary to elaborate all the reasons to disable the “Popup Palette”. For example, for me there are technical reasons. I’m using a pen with a right click button on the side that can be easily activated by accident in drawing mode when creating long strokes.
Yeah…I don’t use it and it’s always popping up when I inadvertently hit the button on my wacom pen…I suppose I could change what that button does but that would change it for other applications as well.
As @cedarfeather states, deactivating the popup palette also deactivates other context menus more useful to them, meaning it’s not a solution for what they’re requesting.
EDIT: I suppose you were intending to reply to @kacart.
The Wacom setup utility has the ability to assign software profiles (like most tablet-setup utilities). Each profile can have different configurations of pen and tablet-buttons, also different pressure-profiles should be possible, or gestures if available.
This might work for a number of users that use a combination of Windows & Wacom tablets, but it’s just a workaround that would require the user to use a non-pen-button for right click in Krita.
Software profiles are often not even available for some tablets and non-Windows-platforms.
For example, for my XP-Pen-Artist there is a sophisticated Linux driver including GUI but it does not have software profiles.
@cedarfeather no, my response was for you, it only desactivate the popup palette, not the other right clic menus …
edit : sorry you’re right, it seems to desactivate all “on canvas” popup, i thought it was just the popup palette.
