springgridlayout

Creator: SpringGridCreator

Helper: SpringGridHelper

This layout is inspired by The Java Tutorial. It is similar to gridlayout, but with some tweaks. Currently, I am strictly using the utility provided in The Java Tutorial, which has a problem in that components in the last row/column can be misaligned with the rest in certain cases. The algorithm used by the utility is not wrong, but it did not make the consideration on the number rounding problem. I will try to find a fix when I have a time. Despite that, the grid generated looks absolutely fantastic.

Example:

<panel>
	<springgridlayout rows="2" columns="2" hgap="5" vgap="5" initialx="5" initialy="5">
		<button text="1" />
		<button text="2" />
		<button text="3" />
		<button text="4" />
	</springgridlayout>
</panel>

springlayout

Class: SpringLayout

SpringLayout is a rather complicated and usually it is best left to a visual GUI generator to do the job.

Example:

<panel>
	<springlayout>
		<label id="box_1" text="this is" />
		<textfield id="box_2" text="for gui builders only" font="Serif,bold italic,20" />
		<textfield id="box_3" text="extra extra long long long .......... field" />

		<springconstraint xpad="5" ypad="5">
			<idref ctor="box_1" />
		</springconstraint>

		<springconstraint xpad="5" preferredheight="true">
			<idref ctor="box_2" />
			<idref ctor="box_1" />
		</springconstraint>
		<springconstraint ypad="5">
			<idref ctor="box_2" />
		</springconstraint>

		<springconstraint>
			<spring setas="height" get="height">
				<idref ctor="box_2" />
			</spring>
			<idref ctor="box_1" />
		</springconstraint>

		<springconstraint xpad="5">
			<idref ctor="box_3" />
		</springconstraint>
		<springconstraint ypad="5">
			<idref ctor="box_3" />
			<idref ctor="box_1" />
		</springconstraint>

		<springconstraint clearwidth="true">
			<idref ctor="box_2" />
		</springconstraint>
		<springconstraint clearwidth="true" clearheight="true">
			<idref ctor="box_3" />
		</springconstraint>

		<springconstraint edge1="East" edge2="East" pad="-5">
			<idref ctor="box_2" />
			<idref ctor="boxparent" />
		</springconstraint>
		<springconstraint edge1="East" edge2="East" pad="-5">
			<idref ctor="box_3" />
			<idref ctor="boxparent" />
		</springconstraint>
		<springconstraint edge1="South" edge2="South" pad="-5">
			<idref ctor="box_3" />
			<idref ctor="boxparent" />
		</springconstraint>
	</springlayout>
</panel>

overlaylayout

Class: OverlayLayout

Example:

<panel>
	<overlaylayout>
		<constraint name="button1">
			<button text="1">
		</constraint>
		<constraint name="button2">
			<button text="2">
		</constraint>
	</overlaylayout>
</panel>
