Overview

This OXP is a utility designed to help OXP authors make use of the upper part of the F7 screen, where the statistics about the currently selected system are displayed.

A new feature added in Oolite v1.85/6 allows the layout of the F7 screen to be completely customised. However, given the number of OXP's that will want to make use of this extra space, there was a need to make the process of adding information to the screen a little more democratic. This OXP aims to provide an centralised interface OXP's can use to make the most of this new feature.

Note: This OXP will only work with Oolite v1.85ff.

Methodology

This OXP offers the following interfaces to OXP's:

systemDataLineOwner

worldScripts.SystemDataConfig.systemDataLineOwner(linenumber : int);

Returns the current owner of a particular data line.

systemDataLineText

worldScripts.SystemDataConfig.systemDataLineText(linenumber : int);

Returns the current text of a particular data line.

setSystemDataLine

worldScripts.SystemDataControl.setSystemDataLine(linenumber : int, text : string [, owner : string]);

Sets the text, and optionally the owner, of a particular data line

resetSystemDataLine

worldScripts.SystemDataControl.resetSystemDataLine(linenumber : int);

Resets the text and owner of a particular data line to be blank.

addChangeCallback

worldScripts.SystemDataControl.addChangeCallback(worldScriptName : string, callbackFunctionName : string);

In order for an OXP to make changes to the F7 screen before it's displayed, two events must be used: guiScreenWillChange (monitoring for when the guiScreen is about to be GUI_SCREEN_SYSTEM_DATA), and infoSystemWillChange. However, because the order in which these events are fired for each OXP is hard to determine, it's quite possible for an OXP's events to be fired after the events within this OXP, which means that updated data might not be displayed.

To work around this issue, OXP's can register a callback function using this call. Then, when those events are triggered for this OXP's, all the callbacks will be executed before the data is displayed, ensuring that the correct data is shown on the screen.

removeChangeCallback

worldScripts.SystemDataControl.removeChangeCallback(worldScriptName : string, callbackFunctionName : string);

This function removes a worldscript/callback function name from the list of callbacks.

Compressed F7 Layout

As an example of what can be achieved with this OXP, the Compressed F7 Layout OXP removes all the blank lines between entries on the F7 screen, compressing the data. It also moves information from Distant Suns and Explorers Club into this section.
