FlexItem¶

A flowable providing a automatic wrapping function and basic css-style styling intended to be used as base-class for better flowables.

Sizing your FlexItem¶

Sizing flowables in ReportLab is build around the wrap(availWidth, availHeight) which allows each flowable to determine how much space they need given the avaliable width and height.

The size of a FlexItem is determined by two things

The min_width, width, max_width, min_height, height and max_height arguments

The size of its content (if it has any), determined by the wrap_content(content_width, content_height) method used to determine the size of the content in the FlexItem. By default wrap_content returns 0, 0

The final size of the FlexItem is the largest of the two. That is if the content of a FlexItem is larger then the FlexItem’s arguments stipulates the content size will take precedence.

Styling¶

Padding¶

Margins¶

Borders¶

Background¶

Adding content¶

Two methods ´´wrap_content´´ and ´´draw_content´´

FlexFlowable¶

A simple utility class which empowers a existing Flowable by wrapping it in a FlexItem.

For example a FlexParagraph which automatically uses half of the avaliable width can be implemented like so:

class FlexParagraph(FlexFlowable):
    def __init__(self, text, style):
        super().__init__(
            flowable=Paragraph(text, style),
            width="50%"
        )
