Visual Script property selector

[Gallilus]

3.3.rc8
WIN 10
GLES3

The visual script editor provides a limited amount of property's to select from.
That the VSeditor gives the same options as GDscript

I will give a example using the Timer Node timer.time_left

I assume this is due to this code difference in propery_selector.cpp vs visual_script_property_selector.cpp
(my understanding of c++ and the Godot project is minimal)

Control drag property
Add visual script try to get any autocomplete hints in the editor

Projects debug.zip

Being able to edit the inspector-property in line edit would be a awesome work around

Similar to #28136

This is because the time_left property is a read-only property. We should probably remove this property for 4.0 in favor of the get_time_left() method, but doing so will break backwards compatibility.

In GDScript, we haven't settled on whether we should expose read-only properties or not. In the meantime, we should only expose getter methods for read-only information.

get_time_left() is also not exposed to VisualScript So I think it is filtered on Property hints.

This issue exists because of this check:

godot/editor/property_selector.cpp

Lines 170 to 172 in 8f7f584

	if (!(E->get().usage & PROPERTY_USAGE_EDITOR) && !(E->get().usage & PROPERTY_USAGE_SCRIPT_VARIABLE)) {
	continue;
	}

Many properties such as Node2D.global_transform have their usage flag set to 0, so they get excluded from the property selector.

I think the property selector should have a "Show all/hidden properties" checkbox to replace the usage flag filter to exclude any PROPERTY_USAGE_GROUP, PROPERTY_USAGE_CATEGORY, or PROPERTY_USAGE_INTERNAL.

This filter could be enabled by default (removing the need for a checkbox) but this risks a regression if any previously-viewable properties accidentally get filtered out.

Just tested after merging of #56252.
Using select from visual script works.
Using select property is still as described above.
