Convenience helpers function Tools::toStdString and Tools::fromStdString
were implemented for Qt4 or older to perform utf8 aware conversion as
QString::toStdString/QString::fromStdString were using toAscii/fromAscii
internally (see https://dreamswork.github.io/qt4/classQString.html).
Since Qt5 QString uses toUtf8/fromUTf8, which makes the helper functions
obsolete (see https://doc.qt.io/qt-5/qstring.html#fromStdString).
* In UIntSpinBox rename the signal to not overwrite the signal of the base class
* In UIntSpinBox use the (ambiguous) signal 'valueChanged' of the base class QSpinBox
* To avoid that connect() fails use the function pointer of the Qt class where the signal is defined
* On lines where the variable type is obvious from inspection, avoid repeating the type using auto.
* When possible use a ranged for loop instead of begin() and end() iterators
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.
- basic infrastructure for handling of expressions
- port the unit properties editor to support expressions
- port placement editor to support expressions
- expressions for double spinbox
- expressions in sketch constraints
