* Add support for better translations (using pluralizations)
* Add support for inserting rows/columns after the selection
* Informs the user that it will insert rows/cols above/under/left/right of the selection
* Informs the user how many rows/cols that will be inserted
As suggested by @luzpaz, this adds a tooltip to the f(x) icon of all
of the widgets that use it: QuantitySpinBox, UIntSpinBox, IntSpinBox,
DoubleSpinBox, and ExpLineEdit. These five classes are divided across
three files, and all five classes duplicate the same basic code. In the
existing code, no tooltip is shown if there is no expression. If there
is an expression, it (alone) is used as the tooltip.
This commit modifies that behavior to have explanatory text as the
tooltip when there is no expression, and when there is, to prepend a
short string to the beginning.
To reduce further code duplication, this is implemented by adding a new
function to ExpressionLabel allowing the text of the expression to be set.
It checks that text and if it's empty, uses a preset default string as the
tooltip. If there is expression text, it instead prepends another
bit of text to the front and sets the entire expression+prefix as the
tooltip.
TODO: In the future a lot of the preexisting code duplication could be
removed by making the ExpressionLabel class do more internal management
of the expression.
Thanks to @kisolre for the assistance tracking these down, and
suggesting the default text used.
OCCT 7.3 did not work well when using a very large projection plane, so
this commit reduces the plane size to the minimum required for the cut
operation. It also performs some minor refactoring in anticipation of
the implementation of the true projection feature, and it removes the
last attempted fix, which proved unnecessary.
This ensures the rotation edge and mode GUI elements are cleared when starting
to add or edit a component. Previously, when adding a new component or
editing one without rotation, the GUI elements would retain the value
from the previously edited component, which made it hard to check that
components did not have any rotation, and would make it easy to
accidentally add rotation to components that did not need it (just by
clicking edit and confirming).
Address a hang when using older versions of OCC to create a rotated
extrusion. This approximates the auxilliary spine as set of line
segments formed from the helix, rather than using the helix directly.
