UserInterfaceGrid Properties

Whether a click where the grid has no child control belongs to the grid or to whatever is behind it. The default is false, so clicks on the padding, on the gaps between cells and on empty cells go through to the viewport, which is what a heads up display over a model wants.

Color the control is filled with: the face of a button, the track of a slider, the box of a check box or radio button, the field of a text box, the whole rectangle of a label, icon or grid. Color.Empty, the default, means the control chooses the color for the theme that is in use and follows the theme when it changes. Labels and icons draw no background when this is Color.Empty. A grid fills with the theme's panel color when it is a top level control, and draws no background when it is inside another control. UserInterfaceGrid.BackgroundOpacity makes the theme color see through, or turns the background off at 0.

How opaque the background is, from 0 (not drawn at all) to 1 (solid, the default). Leave BackgroundColor as Color.Empty and the grid uses the theme's panel color at this opacity, which gives a see through panel over the model that still follows the theme. A BackgroundColor that was set is drawn at this opacity on top of its own alpha. The border is not affected.

Number of cells that have been filled, including the empty ones added with AddEmptyCell. This is not the same as ColumnCount * RowCount.

Number of columns in the grid. The default is 1. Changing the column count reflows the children that have already been added.

Space between columns in logical pixels. The default is 6.

Does this object have keyboard focus? An object with keyboard focus gets first refusal on what is typed in a viewport; what it does not use carries on to the command line as usual.

Number of rows the current children occupy, computed from the child count, the column count and any column spans.

Height of every row in logical pixels. The default is 0, which means each row is as tall as the tallest control in it.

Draw a horizontal line between every pair of rows. Off by default.

Space between rows in logical pixels. The default is 2.

Color used to draw the text. Color.Empty, the default, means use the standard text color for the theme that is in use.

Height of the text in logical pixels. A value of 0, the default, means use the standard control font height. Controls that draw no text ignore this setting.

Where the text sits inside the control's rectangle. This is not the same as HorizontalAlignment, which is where the control sits inside its parent.

Where the text sits inside the control's rectangle. This is not the same as VerticalAlignment, which is where the control sits inside its parent.

Text shown in a tooltip when the mouse rests over this object. Null or an empty string means no tooltip, which is what an object starts with. One tooltip is on screen at a time; whichever object the mouse is over owns it.

3d location that control "sticks" to if not null

Is the user interface object visible? Objects that are not visible will not be drawn and will not receive mouse events
