For window type, size, and position you can do the following:
Specify pop-up window size but not position
Specify secondary window size and position
Override secondary window type
Specify pop-up window size but not position
Only one type of pop-up window can be defined, so in the absence of overrides, all pop-up window-access properties apply to all pop-up links and windows. The only way to specify different sizes for different pop-up windows is by inserting special markers before individual pop-up hotspots; see §20.8.1.5 Overriding window-access properties with markers.
Pop-up window position is not configurable; a pop-up window always pops up immediately under the link.
Specify secondary window size and position
The secondary-window size and position settings listed in Table 20-1 override the default size and position parameters in the helpset file for all secondary windows, making the default values moot. See §20.8.1.1 Assigning default window parameters for JavaHelp 2. The only way to configure different sizes and positions for different secondary window types is by inserting special markers before each jump; see §20.8.1.5 Overriding window-access properties with markers.
Override secondary window type
The default value for [JavaHelpOptions]SecName is empty (see Table 20-1). If you do not include a setting for SecName, for each secondary-window jump the properties specified for that jump in [SecWindows] apply. If you specify a value for SecName, then for all secondary-window jumps, any properties (except size and position) you assign to the SecName window type in its own configuration section override the corresponding properties of whatever window type is specified for the jump in [SecWindows].
