hi andrew

In Sciter2 you can create a snapshot image of a given DOM element with this: var snapshot = new Image(w, h, my_element);

#1 - as I noted, it will make a copy of the DOM element and resize it to the given width and height parameters right?

#2 - if you run the following test, you will note that the created Image is cutting some pixels, from the right and bottom, of the expected snapshot (there shouldn't be a white line between the clones):

<html>
<head>
  <style>
	#source
	{
		size: 150px;
		background-color: blue;
		border-radius: 10px;
	}

	#clone1
	{
		size: 150px;
		background: url(dyn:source-img);
	}

	#clone2
	{
		size: 150px;
		background: url(dyn:source-img);
	}
  </style>

  <script type="text/tiscript">
	self.post( function() {
		var (w,h) = self#source.box(#dimension);
		var img = new Image(w, h, self#source);

		self.bindImage("dyn:source-img", img);
	});
  </script>
</head>

<body>
	<div #source />
	<div #clone1 />
	<div #clone2 />
</body>
</html>

andrew on "Sciter applicable as a modal dialog?"

andrew — Sat, 12 May 2012 20:22:40 +0000

Sciter creates engine instance when SciterProcND receives *either* WM_INITDIALOG or WM_CREATE.

BTW: why not to use view.msgbox() from script for that?

midiway on "Sciter applicable as a modal dialog?"

midiway — Sat, 12 May 2012 16:26:28 +0000

My application will have a modal dialog box as the about/credits area, that is, a HWND created with DialogBox() win32 function.

I want it to be entirely Sciter2 based, but now I am stuck because I had always create Sciter windows with CreateWindowEx passing the Sciter class string.

My workaround will be creating the modal dialog and passing every message from my DlgProc to SciterProcND() function.

Sicter2 is supposed to receive a WM_CREATE message to start the engine right? can it be replaced by a WM_INITDIALOG message?

When I typing in double-byte characters instead of Standard ASCII word

Text output will just fine in win32.exe

Thank you!

andrew — Mon, 07 May 2012 23:19:52 +0000

It is not clear what do you mean here "correct word with 2 extra random byte after it"

AxHTMLayout uses BSTRs that are just sequences of 16 bit code units (unsigned short) - UTF-16 encoded unicode text. So term "byte" is not clear in your message.

Redserpent7 on "Windows 8 and href"

Redserpent7 — Mon, 07 May 2012 00:32:25 +0000

Thanks Andrew, there was an obsolete piese of code that was still being called and it does use ShellExecute to run the href URL. I completely forgot about that since it has been written years ago.

Thanks for the reply..

andrew on "Windows 8 and href"

andrew — Sun, 06 May 2012 17:37:25 +0000

Internally the engine is not passing hyperlink event to the system.

I am pretty sure that this is made inside code of your application while handling either HYPERLINK_CLICK DOM event or in WM_BEHAVIOR_NOTIFY/HLN_HYPERLINK notification.

Check your code for calls of ShellExecute. Seems like you are passing URL to that function and it produces that warning.

Redserpent7 on "Windows 8 and href"

Redserpent7 — Sun, 06 May 2012 00:42:34 +0000

I am testing my software on windows 8 to see if there are any problems. I know the RC is yet to come out but on the Customer Preview version I am facing a problem with <a> tags and internal href.

for example I have this link in one of my pages:

<a id="DOSTART" href="MYCOMMAND:GOTOPAGE:START">START</a>

it seems that in windows 8 MS has done something that tries to control all links clicked in a any software, probably to handle METRO apps.

Every time I click on the link above windows prompt me with a message stating "No apps are installed to open this type of link (mycommand)"

I never had a problem in previous versions of windows as I've been using the same method for years.

Is this a known issue that will be fixed soon? or is there a way to get around it using current builds of htmlayout?

Regards

but it doesnt work =( in Sciter2

andrew — Thu, 03 May 2012 21:33:37 +0000

selectAll has additional boolean parameter:

ed.selectAll(true); // do select all.
var canSelectAll = ed.selectAll(false);

midiway on "how to make a element focusable?"

midiway — Thu, 03 May 2012 11:57:53 +0000

Ops, I posted in the wrong forum, it should be in the Sciter area

In Sciter, you dont use xcall() right?
I suppose ed.selectAll() is the alternative in Sciter, but I tested and it does nothing in Sciter2.

I am calling it, the engine recognizes the method since it does not throws an exception, but it is not selecting the input text-content

kagachiu on "AxHTMLayout double-byte input problem"

kagachiu — Tue, 01 May 2012 16:11:53 +0000

Hi!

In using AxHTMLayout VB example
I found that All text field with double-byte characters input method (for example: Chinese characters) will output a correct word with 2 extra random byte after it.
But everything will just fine if using Copy'n Paste method only.
Also this will not happen in SDK include example mfc_browse.exe, win32.exe or browse.exe.
So, I believed that there is something wrong in AxHTMLayout.dll with double-byte IME
Unfortunately, I am not familiar with C++! So, can you give me a hint how to fix this?
I already using the newest AxHTMLayout.dll and htmlayout.dll

Please excuse my poor english and thank you in advance!

midiway on "Sciter2 Graphics.Path"

midiway — Mon, 30 Apr 2012 10:42:49 +0000

well, it is just one of those situation where it is more logical to clone the path than to draw it again (which is much more performance extensive than cloning)

var lPathHat = function(path) {
	path.moveTo(0, ns_fx.ARC_RADIUS, true);
	path.arcTo(ns_fx.ARC_RADIUS, 0, 0, ns_fx.ARC_RADIUS, ns_fx.ARC_RADIUS, false, true);
	path.lineTo(rcSubTab.w-ns_fx.ARC_RADIUS, 0);
	path.arcTo(rcSubTab.w, ns_fx.ARC_RADIUS, 0, ns_fx.ARC_RADIUS, ns_fx.ARC_RADIUS, false, true);
};

var path_top = new Graphics.Path();
lPathHat(path_top);
path_top.lineTo(rcSubTab.w, rcSubTab.h/2+0.5);
path_top.lineTo(-rcSubTab.w, 0, true);
path_top.close();

var path_full = new Graphics.Path();
lPathHat(path_full);
path_full.lineTo(rcSubTab.w, rcSubTab.h-ns_fx.ARC_RADIUS);
path_full.arcTo(rcSubTab.w-ns_fx.ARC_RADIUS, rcSubTab.h, 0, ns_fx.ARC_RADIUS, ns_fx.ARC_RADIUS, false, true);
path_full.lineTo(ns_fx.ARC_RADIUS, rcSubTab.h);
path_full.arcTo(0, rcSubTab.h-ns_fx.ARC_RADIUS, 0, ns_fx.ARC_RADIUS, ns_fx.ARC_RADIUS, false, true);
path_full.close();

see, I am calling the lPathHat lambda 2x times when I could just clone the path

andrew on "Sciter2 Graphics.Path"

andrew — Mon, 30 Apr 2012 09:07:15 +0000

As of cloning Graphics.Path ...

There is no such method at the moment.

Could you explain why do you need to clone the path?

andrew on "Sciter2 Graphics.Path"

andrew — Mon, 30 Apr 2012 08:49:16 +0000

These are remnants from S1.

drawPath() uses lineColor/line***Gradients to draw the outline and fillColor/fill***Gradient to fill the path.

If you don't need one of those use Graphics.noLine() or Graphics.noFill()

andrew on "Sciter2 DLL does not exports TIScriptAPI()"

andrew — Mon, 30 Apr 2012 08:45:08 +0000

Next build will have this function exported.

midiway on "Sciter2 DLL does not exports TIScriptAPI()"

midiway — Sat, 28 Apr 2012 21:37:21 +0000

TIScript has the TIScriptAPI() exported function which exposes its entire native functionality

I am using some of the TIScriptAPI functions, but my linker says:
error LNK2019: unresolved external symbol __imp__TIScriptAPI@0

Well, my applicatio is using Sciter2, and Sciter2 is linked against TIScript source code right? so it should be exporting it..

I checked with Dependency Walker, and Sciter2 DLL really is not exporting it. However, Sciter1 DLL has this export.

midiway on "Sciter2 Graphics.Path"

midiway — Sat, 28 Apr 2012 12:55:18 +0000

How to clone a given Graphics.Path instance?

What is the purpose of Graphics.FILL_ONLY, Graphics.STROKE_ONLY, Graphics.STROKE_AND_FILL and Graphics.FILL_BY_LINE_COLOR constants? drawPath() has no parameters for those flags and Graphics class has no property for it.

heiko07 on "Reducing size of htmlayout dll"

heiko07 — Thu, 26 Apr 2012 06:24:17 +0000

Hi Andrew

Any tips/pointers on how to reduce size of htmlayout.dll ?

I switched off SVG_SUPPORT, JPG_SUPPORT, BMP_SUPPORT, ACCESSIBLE, RICHTEXT, PRINTEX_SUPPORT

Got final htmlayout.dll to 650kb (with UPX Ultra-Brute)

Are there any other features that I could possibly switch off, if not used.
Other defines, or functional/modular components that I might not need.

(Building with Visual Studio 2010, Htmlayout version 3.3.3.8)

tnx,
Heiko

andrew — Mon, 23 Apr 2012 18:55:33 +0000

#1 I've fixed WM_KILLFOCUS handling, will publish build soon.

var ed = ...
 ed.state.focus = true;
 ed.xcall(#selectAll,true);

Do it through xcall because selectAll is a method of Element class.

#3 single line editor does not handle VK_RETURN so KEY_DOWN|VK_RETURN is propagated
further not handled.

midiway on "how to make a element focusable?"

midiway — Mon, 23 Apr 2012 10:57:36 +0000

#3 - just for curiosity, does the 'edit' behavior (single line) generates any kind of synthetic event when the user presses ENTER key while it has focus?

midiway on "how to make a element focusable?"

midiway — Sun, 22 Apr 2012 20:23:21 +0000

OK, I made this question because I was working around this bug in Sciter2:

#1 - It is not handling WM_KILLFOCUS, so if the focus is in an <input type="text" />, and I move the focus to another HWND, the caret still blinks. So I had to manually kill the focus in Sciter by handling WM_KILLFOCUS and calling this TIScript function:

function Extern_KillFocus()
{
  view.focus = undefined;
}

#2 - another question, if I have this text element <input type="text" #myInput />, how to select all the text-value in the input? I tried doing the following, calling selectAll() from the 'edit' behavior, but it does nothing:

self#myInput.selectAll(true);

finally, will selectAll() steal the focus?

andrew on "how to make a element focusable?"

andrew — Sun, 22 Apr 2012 20:03:02 +0000

To make element focusable do either one of these:

1. Declare tabindex=0...N on it or,
2. in tiscript declare onFocus handler either on element itself or in behavior attached to it, or
3. in CSS declare focus-on!: ; on it.

midiway on "how to make a element focusable?"

midiway — Sun, 22 Apr 2012 17:08:06 +0000

as the title says, I want a given element to participate in the focus handling mechanism, so when I press TAB it get the focus

also, as I am working with a DIV element, it needs to know when it get the focus, so this CSS rule must be applied:

div#myFocusWidget:focus
{
}

and also its internal FOCUS state must be set:

assert(self#myFocusWidget.states.focus == true)

BTW, I can imagine how tricky is focus handling, you know, just see how Windows must cheat with IsDialogMessage()

andrew on "Sciter2 scripting - Graphics linear gradient with multiple colors stop"

andrew — Sun, 22 Apr 2012 10:00:27 +0000

I'll add support of multi-color gradients to Graphics.
sciter-x-graphin.h will also be supported and it will use Direct2D underneath.

midiway on "Sciter2 scripting - Graphics linear gradient with multiple colors stop"

midiway — Sat, 21 Apr 2012 17:36:50 +0000

andrew

As of the last preview version of Sciter2, in script, you can specify a linear gradients (for fill and line) with only 2 colors, that is, the starting and ending color

I think in Sciter1 you could make a gradient with multiple colors using the native 'sciter-x-graphin.h' API, but not through scripting.

I would be fine if I could also do it in Sciter2, with a native interface. Or better, make it possible through scripting by having overloaded forms for Graphics.fillLinearGradient() and Graphics.lineLinearGradient(), or with different names

I am not sure why you removed the 'sciter-x-graphin.h' API from Sciter2. I guess that Sciter2 is now entirely based on Direct2D, so you dropped the AntiGrain library cause it is not hardware accelerated.

There are sources of AxHTMLayout.dll in the SDK. You can compile them with debug info and it will give you location where it crashes.

Note that AxHTMLayout is just an example of how ActiveX wrapper can be made. Fill free to change/fix it in the way you want.
