NAME

Win32::GUI::GridLayout - Grid layout support for Win32::GUI

SYNOPSIS

    use Win32::GUI::
    use Win32::GUI::GridLayout;

    # 1. make a "static" grid
    $grid = new Win32::GUI::GridLayout(400, 300, 3, 3, 0, 0);
    
    $win = new Win32::GUI::Window(
    
    $win->AddLabel(
        -name => "label1",
        -text => "Label 1",
        -width  => $grid->width(35),
        -height => $grid->height(11),
        -left   => $grid->col(1, "left"),
        -top    => $grid->row(1, "top"),
    );
    
    # 2. make a "dynamic" grid
    $grid = apply Win32::GUI::GridLayout($win, 3, 3, 0, 0);
    
    $win->AddLabel(
        -name => "label1",
        -text => "Label 1",
    );
    $grid->add($win->label1, 1, 1, "left top");

    $grid->recalc();

DESCRIPTION

Constructors

new Win32::GUI::GridLayout(WIDTH, HEIGHT, COLS, ROWS, XPAD, YPAD)

apply Win32::GUI::GridLayout(WINDOW, COLS, ROWS, XPAD, YPAD)

Methods

add(CONTROL, COL, ROW, ALIGN)

Adds CONTROL to the grid at (COL, ROW). ALIGN can specify both horizontal and vertical alignment (see the col() and row() methods), separated by at least one blank and/or a comma.

Example:

    $grid->add($win->label1, 1, 1, "left top");

col(N, ALIGN)

Positions the control at the Nth column in the grid, optionally with an ALIGN; this can be feed to a -left option when creating a control.

ALIGN can be left, center or right (can be shortened to l, c, r); default is left.

Note that for alignment to work properly, the width() and height() methods must have been previously called.

Example:

    $win->AddLabel(
        -name => "label1",
        -text => "Label 1",
        -width  => $grid->width(35),
        -height => $grid->height(11),
        -left   => $grid->col(1, "left"),
        -top    => $grid->row(1, "top"),
    );      

draw()

Draws the GridLayout in the associated window (may be useful for debugging); is only meaningful if the GridLayout was created with the apply() constructor.

height(N)

Sets the height of the control for subsequent alignment; this can be feed to a -height option when creating a control.

Example: see col().

recalc()

Recalculates the grid and repositions all the add()ed controls, taking into account the actual window and controls sizes; is only meaningful if the GridLayout was created with the apply() constructor.

Example:

    sub Window_Resize {
        $grid->recalc();
    }

row(N, ALIGN)

Positions the control at the Nth row in the grid, optionally with an ALIGN; this can be feed to a -top option when creating a control.

ALIGN can be top, center or bottom (can be shortened to t, c, b); default is top.

Note that for alignment to work properly, the width() and height() methods must have been previously called.

Example: see col().

width(N)

Sets the width of the control for subsequent alignment; this can be feed to a -width option when creating a control.

Example: see col().
