如何有效地隐藏\取消隐藏 GUI 元素？

我有一个 GUI，它可以根据选择器隐藏或取消隐藏某些元素。

现在，我已经封装了在相应的 If Box() 中发生变化的所有元素，并且当 ComboBox 选择器发生变化时，每个元素都会发生变化，如下所示：

Names Default To Here( 1 );

modeSelectorOptions = {"Mode1", "Mode2"};
gui = V List Box(
	modeSelector = ComboBox(modeSelectorOptions, 
		<< Set Function(
			Function(
				{this}, 
				Match(this << Get Selected(),
				modeSelectorOptions[1], Write("\!nMode1");IB1<< Set (1); IB2 << Set(0)/*many more when script expanded*/,
				modeSelectorOptions[2],	Write("\!nMode2");IB1<< Set (0); IB2 << Set(1)/*many more when script expanded*/,
				)
			)
		);
	),
	Button Box("All Modes", Write("Always active")),
	IB1 = If Box(1, Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))), 
	IB2 = If Box(0, Button Box("GUI ELEMENT for Mode2", Write("Button pressed")))
	
);

NW = New Window("Test",<< Show Toolbars(0),<<SHOWMENU></SHOWMENU>

This works, but it is not very scalable.

I need to hide or unhide certain elements depending on the mode throughout the whole window with many elements. I have to encapsulate each of those changing elements in an If Box(), name it and don't forget to include it in the Match statement of the <EM>模式选择器</EM>.

It is not very scalable, especially when I move into 10-20 different elements.

Is there any way to, let's say, just raise a corresponding flag in Match statement, define all the IF boxes with those flags and then just give command to redraw them?

Something like this, where redrawIfBoxes is an expression that redraws all the IF boxes so that changed flag takes effect:

<CODE class=" language-jsl">Names Default To Here( 1 );

modeSelectorOptions = {"Mode1", "Mode2"};
mode1Flag = 1;
mode2Flag = 0;
gui = V List Box(
	modeSelector = ComboBox(modeSelectorOptions, 
		<< Set Function(
			Function(
				{this}, 
				Match(this << Get Selected(),
				modeSelectorOptions[1], Write("\!nMode1");mode1Flag = 1;mode2Flag = 0;redrawIfBoxes,
				modeSelectorOptions[2],	Write("\!nMode2");mode1Flag = 0;mode2Flag = 1;redrawIfBoxes,
				)
			)
		);
	),
	Button Box("All Modes", Write("Always active")),
	IB1 = If Box(mode1Flag, Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))), 
	IB2 = If Box(mode2Flag, Button Box("GUI ELEMENT for Mode2", Write("Button pressed")))
	
);

NW = New Window("Test",<< Show Toolbars(0),<<SHOWMENU></SHOWMENU>

目前我已经这样做了：

Names Default To Here( 1 );

modeSelectorOptions = {"Mode1", "Mode2"};
mode1Flag = 1;
mode2Flag = 0;
mode1IfBoxes = {IB1, IB3, IB5};
mode2IfBoxes = {IB2, IB4, IB6};
gui = V List Box(
	modeSelector = ComboBox(modeSelectorOptions, 
		<< Set Function(
			Function(
				{this}, 
				Match(this << Get Selected(),
				modeSelectorOptions[1], Write("\!nMode1");mode1Flag = 1;mode2Flag = 0;redrawIfBoxes,
				modeSelectorOptions[2],	Write("\!nMode2");mode1Flag = 0;mode2Flag = 1;redrawIfBoxes,
				)
			)
		);
	),
	Button Box("All Modes", Write("Always active")),
	IB1 = If Box(mode1Flag, Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))), 
	IB2 = If Box(mode2Flag, Button Box("GUI ELEMENT for Mode2", Write("Button pressed"))),
	IB3 = If Box(mode1Flag, Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))), 
	IB4 = If Box(mode2Flag, Button Box("GUI ELEMENT for Mode2", Write("Button pressed"))),
	IB5 = If Box(mode1Flag, Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))), 
	IB6 = If Box(mode2Flag, Button Box("GUI ELEMENT for Mode2", Write("Button pressed")))
	
);
redrawIfBoxes = Expr(
	mode1IfBoxes << Set (mode1Flag);
	mode2IfBoxes << Set (mode2Flag);
);

NW = New Window("Test",<< Show Toolbars(0),<<SHOWMENU></SHOWMENU>

Let me know if there is a more robust way.<BR />With more modes redrawIfBoxes can be changed from Expression to Function to match list of IfBoxes to a specific flag without ever needing to update the function.

The only two places to update - lists of If Boxes and Match statement in selector combobox.

取决于您的最终应用程序以及您认为什么“强大”且易于管理，但有不同的选择：

• 你可以使用 if 框
  • XPath 可能会有帮助
  • 你也可以将按钮包裹在某个容器内，这样每个模式只需要一个 if 框
• 您可以使用 << Visibility("Collapse")
• 当发生变化时，你可以动态更新按钮文本/操作

不一定是我所采用的方式，但这只是提供一些潜在的想法

Names Default To Here( 1 );

mode_options = {"Mode1", "Mode2"};

gui = V List Box(
	modeSelector = ComboBox(modeSelectorOptions, 
		<< Set Function(Function({this},
			this << Inval;
			selection = Contains(mode_options, this << Get Selected);
			ibs << Set(0);
			ibs[selection] << Set(1);
			this << Update Window;
		));
	),
	Button Box("All Modes", Write("Always active")),
	If Box(0, 
		V List Box(
			Button Box("GUI ELEMENT for Mode1", Write("Button pressed")),
			Button Box("GUI ELEMENT for Mode1", Write("Button pressed")),
			Button Box("GUI ELEMENT for Mode1", Write("Button pressed"))
		)
	),
	If Box(0, 
		V List Box(
			Button Box("GUI ELEMENT for Mode2", Write("Button pressed")),
			Button Box("GUI ELEMENT for Mode2", Write("Button pressed")),
			Button Box("GUI ELEMENT for Mode2", Write("Button pressed"))
		)
	)
);

ibs = gui << Xpath("//IfBox");

// JMP things
modeSelector << Set(2, Run Script(0));
modeSelector << Set(1, Run Script(1));

nw = New Window("Test",<< Show Toolbars(0),<<SHOWMENU></SHOWMENU>
