Let's say that we want odd grid lines to be a bit brighter
since they only show 30 min boundaries.
Grid lines are repetition specifications evaluated in the order
they exist in the property list stored under the key:
String primGLKey = CalendarTheme.KEY_GRID_GRIDLINES_ + “PrimaryDim#”;
Default there is a GridLineRepetition that says: 'start at
grid line 0 and accept every grid line, setting color to gray
and width to 1'.
We can leave that repetition be and insert a new repetition
that goes something like: 'start at index 1 and accept every
second grid line, setting color to light gray and width to 1'.
Since this repetition is before the default one it is evaluated
first. It will only specify a 'hit' on odd grid lines though,
making them light gray. All other grid lines will be caught by
the second, default, rule making all other grid lines darker
gray.
You can easily insert repetitions that just changes a single
grid line, for instance the first or last or around lunch or
whatever. You can even reference them from the last grid line
making them very flexible to work with even if you don't
know beforehand how many you have. You could even say
that the middle 15% of the grid lines should be five pixels
wide and painted yellow..
Here are some code that make odd grid lines lighter a lighter
gray:
String glKey = CalendarTheme.KEY_GRID_GRIDLINES_ + “PrimaryDim#”;
GridLineRepetition glRep = new GridLineRepetition(1, 2, 1, new Color(245, 245, 245));
theme.addToList(glKey, 0, glRep); // add at index 0 to make first key in the list
