After MXE is installed `make qtbase` should build and install the required dependencies to build QTeletextMaker.

 ## Building
 ### Linux
-Install the QtCore, QtGui and QtWidgets libraries and build headers, along with the qmake tool. Depending on how qmake is installed, type `qmake && make -j3` or `qmake5 && make -j3` in a terminal to build, you can replace -j3 with the number of processor cores used for the compile process.
+Install version 5 or 6 of the QtCore, QtGui and QtWidgets libraries and build headers, along with the qmake tool. Depending on how qmake is installed, type `qmake && make -j3` or `qmake5 && make -j3` or `qmake6 && make -j3` in a terminal to build, you can replace -j3 with the number of processor cores used for the compile process.

 The above should place the qteletextmaker executable in the same directory as the source, type `./qteletextmaker` in the terminal to launch. Some Qt installs may place the executable into a "release" directory.

 The following X/26 enhancement triplets are not rendered by the editor, although the list is fully aware of them.
 - Invocation of Objects from POP and GPOP pages.
 - DRCS characters.
- Modified G0 and G2 character set designation using X/26 triplets with mode 01000.
 - Proportional font spacing on Level 3.5

 ## Using the X/26 triplet editor
@@ -46,7 +47,7 @@ Most triplet modes will present varying widgets below which can be used to alter

 By checking "raw values" it is also possible to view and edit the raw Address, Mode and Data numbers of the triplets. When editing triplets this way, remember that address values 0-39 select a column triplet which has one set of modes and address values 40-63 select a row triplet which has a different set of modes.

-The full behaviour of X/26 enhancement triplets can be found in section 12.3 of the [Enhanced Teletext specification ETS 300 706](https://web.archive.org/web/20160326062859/https://www.phecap.nl/download/enhenced-teletext-specs.pdf).

 ### Setting the Active Position
 The Active Position, whether set explicitly by a "Set Active Position" triplet or by a row or column triplet, can only be moved in screen address order i.e. from left to right within a row and then from top to bottom across rows. In other words:

G.K.MacGregor	f36143e10f	Really show correct G0 and G2 character set in widgets Amendment to `7b59c78`. This should prevent spurious NOS character sets from appearing in the widgets, and should also prevent the G0 and G2 character sets from getting mixed up in the widgets when those triplets are within object definitions. The G0 and G2 character set in the widgets may still be incorrect in corner cases of objects invoked within areas of the page where the character set has been changed either with the ESC/Switch spacing attribute or with the "modified G0/G2 character set designation" triplet.	2023-08-15 18:11:40 +01:00
