multiple "setvisible = false" how do I ....

[teedee]

Hi,

Is it possible to easily (and quickly ) set multiple "setvisible = false" actions to a button.

I require that each of 10 buttons sets "setvisable = false" to 8 - 10 buttons on a page whilst similtainiously (sp) setting "setvisable = true" to another range of 8 - 10 buttons

Looking for a way to do this without adding each action individually and cutting down on the actual code required to perform these action.

Thanks again

What I've done in the past is have each button end with a Numeric Value, like Button1 , Button2

then use a for loop, concatate the loop variable to your button name.

Add 10 buttons to a page leaving the buttons named Button1 through Button10. Set the visible property on some of them to false.

Then use this code to swap the hidden buttons with the visible ones:

for n=1, 10 do
--hide all visible buttons and show all hidden
Button.SetVisible("Button"..n,not Button.IsVisible("Button"..n))
end

If you don't want to name your objects that way, there are two other methods you can use.

1. Create a table containing the names of the objects you want to modify, and then use a for loop to walk through the table, showing or hiding all the objects in the list.

2. Use Page.EnumerateObjects and Page.GetObjectType to operate on all the objects of a given type (e.g. all the buttons) on the page.

Use method 1 if you don't want to modify all of the objects of that type on the page (e.g. you want to modify 8 out of 12 button objects). Use method 2 if you don't want to have to update the table whenever you add objects to the page or rename them.

That sounds more like I need, can you elaborate a little bit more how to do this, 1st time for me and I am reying to learn all this

Thanks

Here's a function that uses method 2 to do a set visible on all the buttons on the current page.

AllButtons = {};
function AllButtons.SetVisible(bVisible)
	local tbObjects = Page.EnumerateObjects();
	for index, name in tbObjects do
		if Page.GetObjectType(name) == OBJECT_BUTTON then
			Button.SetVisible(name,bVisible);
		end
	end	
end

Here's an example of calling that function:

-- show all buttons
AllButtons.SetVisible(true);

-- hide all buttons
AllButtons.SetVisible(false);

Here's an example of method 1:

MyButtons = {"Button1","Button2","Button3"};
function HideMyButtons()
	for index, name in MyButtons do
		Button.SetVisible(name,false);
	end
end

function ShowMyButtons()
	for index, name in MyButtons do
		Button.SetVisible(name,true);
	end
end

-- hide the buttons listed in the 'MyButtons' table
HideMyButtons();

Here's a more advanced example that can handle different object types:

Objects = {};
function Objects.SetVisible(tbObjectNames, bVisible)
	for index, name in tbObjectNames do
		local obtype = Page.GetObjectType(name);
		if obtype == OBJECT_BUTTON then
			Button.SetVisible(name, bVisible);
		elseif obtype == OBJECT_FLASH then
			Flash.SetVisible(name, bVisible);
		elseif obtype == OBJECT_IMAGE then
			Image.SetVisible(name, bVisible);
		elseif obtype == OBJECT_INPUT then
			Input.SetVisible(name, bVisible);
		elseif obtype == OBJECT_LABEL then
			Label.SetVisible(name, bVisible);
		elseif obtype == OBJECT_LISTBOX then
			ListBox.SetVisible(name, bVisible);
		elseif obtype == OBJECT_PARAGRAPH then
			Paragraph.SetVisible(name, bVisible);
		elseif obtype == OBJECT_PLUGIN then
			Plugin.SetVisible(name, bVisible);
		elseif obtype == OBJECT_VIDEO then
			Video.SetVisible(name, bVisible);
		elseif obtype == OBJECT_WEB then
			Web.SetVisible(name, bVisible);
		else
			Debug.Print("Error: "..name.." - Invalid object type.");
		end
	end
end

-- hide Button1, Button2 and Label5
MyObjects = {"Button1","Button2","Label5"};
Objects.SetVisible(MyObjects, false);

thanks, still trying to get my head around this so I can understand it.........

any chance you could throw together a couple of working examples so I can see where the code goes (can't even seem to get that right :( )and what happems when I modify it ?

Thanks again, I appreciiate the help.

Here you go. Be sure to look in the following places:

Project > Global Functions
Page - On Preload
Button4 - On Click
Button5 - On Click

Thank you so much

I find it so much easier to learn playing with a working version and then brealing it to suit my needs

Thanks again
