Struct native_windows_gui::GridLayout

pub struct GridLayout { /* fields omitted */ }

A layout that lays out widgets in a grid NWG layouts use interior mutability to manage their controls.

A GridLayouts has the following properties:

• margin - The top, right, bottom, left margins of the layout - (default: [5, 5, 5, 5])
• spacing - The spacing between children controls - (default: 5)
• min_size - The minimum size of the layout - (default: [0, 0])
• max_size - The maximum size of the layout - (default: [u32::max_value(), u32::max_value()])
• max_column - Number of columns - (default: None),
• max_row - Number of rows - (default: None),

    use native_windows_gui as nwg;
    fn layout(layout: &nwg::GridLayout, window: &nwg::Window, item1: &nwg::Button, item2: &nwg::Button) {
        nwg::GridLayout::builder()
            .parent(window)
            .max_row(Some(6))
            .spacing(5)
            .margin([0,0,0,0])
            .child(0, 0, item1)
            .child_item(nwg::GridLayoutItem::new(item2, 1, 0, 2, 1))
            .build(&layout);
    }

Implementations

impl GridLayout

pub fn builder() -> GridLayoutBuilder

pub fn add_child<W: Into<ControlHandle>>(&self, col: u32, row: u32, c: W)

Add a children control to the grid layout. This is a simplified interface over add_child_item

Panic:

• If the layout was not yet initialized
• If the control is not window-like (HWND handle)

pub fn add_child_item(&self, i: GridLayoutItem)

Add a children control to the grid layout.

Panic: - If the layout was not yet initialized - If the control is not window-like (HWND handle)

pub fn remove_child<W: Into<ControlHandle>>(&self, c: W)

Remove the children control in the layout. See also remove_child_by_pos. Note that the child control won't be hidden after being removed from the control.

Panic:

• If the layout was not yet initialized
• If the control is not in the layout (see has_child)

pub fn remove_child_by_pos<W: Into<ControlHandle>>(&self, col: u32, row: u32)

Remove the children control in the layout. See also remove_child_by_pos. Note that the child control won't be hidden after being removed from the control.

This method won't do anything if there is no control at the specified position.

Panic:

• If the layout was not yet initialized

pub fn has_child<W: Into<ControlHandle>>(&self, c: W) -> bool

Check if a window control is a children of the layout

Panic:

• If the layout was not yet initialized
• If the control is not in the layout (see has_child)

pub fn resize(&self, w: u32, h: u32)

Resize the layout as if the parent window had the specified size.

Arguments: w: New width of the layout h: New height of the layout

Panic:

• The layout must have been successfully built otherwise this function will panic.

pub fn fit(&self)

Resize the layout to fit the parent window size

Panic:

• The layout must have been successfully built otherwise this function will panic.

pub fn margin(&self, m: [u32; 4])

Set the margins of the layout. The four values are in this order: top, right, bottom, left.

pub fn spacing(&self, sp: u32)

Set the size of the space between the children in the layout. Default value is 5.

pub fn min_size(&self, sz: [u32; 2])

Sets the minimum size of the layout

pub fn max_size(&self, sz: [u32; 2])

Sets the maximum size of the layout

pub fn max_column(&self, count: Option<u32>)

Set the number of column in the layout

pub fn max_row(&self, count: Option<u32>)

Set the number of row in the layout

Trait Implementations

impl Clone for GridLayout

fn clone(&self) -> GridLayout

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for GridLayout

fn default() -> GridLayout

Returns the "default value" for a type.
