CodeSnip Old Code (SVN)

Help index and various topics updated re changes in Preference dialogue box in splitting out display options onto own tab and renaming of "General" tab to "Misc."

Split dlg_prefs_general help topic into two, one each for new tabs derived from old "General" tab of Preferences dialogue box.
dlg_prefs_general topic retains info about measurement units and is retitled "Misc."
New dlg_prefs_display receives info about "Display" tab.
Project file updated with reference to new topic.

Split General Preferences frame into two: Miscellaneous (containing measurement units) and Display, containing all display related options.
Note: FrGeneralPrefs unit now contains only measurement units and displays on "Misc." tab. Options that display on "Display" tab in new FrDisplayPrefs unit.

Changed TPrintInfo to descend from TSingleton.

Changed TQuery to descend from TSingleton.

Modified TSingleton to implement IInterface methods without reference counting.

Changed make file to use INNOSETUP_U environment variable for Inno Setup path in preference to INNOSETUP.
Updated Build.html re this change.

Noted that Inno Setup 5.5.1 (Unicode) is now required for setup. Changed wording now that ISPP is included by default.

Added USingleton unit (r2018) to project. This unit was copied from new-backend branch at r2012.

Changed TNoConstructObject, TNoPublicConstructObject and TNoPublicConstructIntfObject constructors to raise ENoConstructException exceptions instead of assertion failures.
This was done because it is standard practice (and used by VCL) and it also enables unit tests that expect these exceptions to be passed.
