BreakpointCondition.parse

Parses a condition from a string.

Length conditions are specified as <type>: <value>[<unit>], where:

  • <type> can be min-width, max-width, min-height or max-height
  • <value> is a fractional number
  • <unit> can be px, pt or sp

If the unit is omitted, px is assumed.

See adw.breakpoint_condition.BreakpointCondition.newLength.

class BreakpointCondition
static
parse
(
string str
)

Parameters

str string

the string specifying the condition

Return Value

Type: adw.breakpoint_condition.BreakpointCondition

the parsed condition

Examples

  • min-width: 500px
  • min-height: 400pt
  • max-width: 100sp
  • max-height: 500

Ratio conditions are specified as <type>: <width>[/<height>], where:

  • <type> can be min-aspect-ratio or max-aspect-ratio
  • <width> and <height> are integer numbers

See adw.breakpoint_condition.BreakpointCondition.newRatio.

The ratio is represented as <width> divided by <height>.

If <height> is omitted, it's assumed to be 1.

  • min-aspect-ratio: 4/3
  • max-aspect-ratio: 1

The logical operators and, or can be used to compose a complex condition as follows:

  • min-width: 400px and max-aspect-ratio: 4/3
  • max-width: 360sp or max-width: 360px

Conditions can be further nested using parentheses, for example:

  • min-width: 400px and (max-aspect-ratio: 4/3 or max-height: 400px)

If parentheses are omitted, the first operator takes priority.
