Method Details

columnContainsComponent
Checks and answers whether the given FormLayout container contains a component in the specified column.For every container child component, we look up the associated
CellConstraints
object from the layout and compare its horizontal grid origin with the specified column index.- Parameters:
container
- the layout containercolumnIndex
- the index of the column to test- Returns:
- true if the column contains a component, false otherwise
- Throws:
IllegalArgumentException
- if the container's layout is not aFormLayout
-
rowContainsComponent
Checks and answers whether the given FormLayout container contains a component in the specified row.For every container child component, we look up the associated
CellConstraints
object from the layout and compare its vertical grid origin with the specified row index.- Parameters:
container
- the layout containerrowIndex
- the index of the row to test- Returns:
- true if the row contains a component, false otherwise
- Throws:
IllegalArgumentException
- if the container's layout is not aFormLayout
-
isGroupedColumn
Checks and answers whether the specified column is grouped in the given FormLayout. A columncol
is grouped, if and only if there's a column group group that includescol
's index.- Parameters:
layout
- the layout to be inspectedcolumnIndex
- the index of the column to be checked- Returns:
- true if the column is grouped, false if not
-
isGroupedRow
Checks and answers whether the specified row is grouped in the given FormLayout. A rowrow
is grouped, if and only if there's a row group group that includesrow
's index.- Parameters:
