Strictly speaking, can you say that nothing has happened, that no evaporation or condesation has taken place? Explain please

No, you can't say nothing has happened. Water evaporates until the system reaches equilibrium. As the temperature rises and falls, the air in the glass will contain a little more or less water, but there is no major change. If condensation occurs, the water falls back into the glass. It is a closed system in equilibrium.

Since there is a cover over the glass no air can get to the water to cause evaporation. And if the water is room temperature..there can be no condensation.

Well, it tries to evaporate, but being covered, there isn't anywhere for the water to go except back down into the glass.

Condensation may happen but it will return to the glass. It can't evaporate if there is a lid.

If the covered glass is maintained at STP, then Yes because there is no increase or decrease in pressure.
