Assistant won't display short htmls. Why? Is that a bug?

**Raadush** · 23rd October 2012, 13:23

Hi. Came across strange issue. I have html page, created .qhp, .qch, .qhcp and .qhc files as usuall, but Assistant haven't displayed that page when I cliced on corresponding leaf in tree structure of assistant. After further testing where the problem could be, I figured out, that the problem is in length of html page. This test page:

Qt Code:

Switch view

<html>
<h1>Test</h1>
Test
</html>

<html>
<h1>Test</h1>
Test
</html>

To copy to clipboard, switch view to plain text mode

will not get displayed. Neither this one:

Qt Code:

Switch view

<html>
<h1>Test</h1>
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTest
</html>

<html>
<h1>Test</h1>
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTest
</html>

To copy to clipboard, switch view to plain text mode

But after adding another character behind last "Test" the page is suddently displayed correctly. Anybody have some idea why is that? Is that a bug? I want to create really short help page telling what happens when user click Exit in my app.

What happens if you wrap the content in <body> tags?

**Raadush** · 24th October 2012, 07:00

The same thing. Only shortens page content which causes the error a bit

Qt Code:

Switch view

<html>
<body>
<h1>Test</h1>
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestT
</body>
</html>

<html>
<body>
<h1>Test</h1>
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest
TestTestTestTestTestT
</body>
</html>

To copy to clipboard, switch view to plain text mode

not being displayed, +1 character displayed correctly

**Raadush** · 26th October 2012, 07:20

So? Anyone some advice? Or there's nothing to be done?

**Raadush** · 30th October 2012, 07:17

Still anyone?

Besides of this strange behavior, I found very hard to make assistant do what I want to do.

**wysota** · 30th October 2012, 09:01

Are you using the webkit backend for assistant or the text browser backend?

**Raadush** · 31st October 2012, 08:36

Neither one? Im using set of html pages on hard-drive loaded via <files></files> element in help.qhp file. Doing nothing programatically with anything so far, just calling assistant from terminal

You have to be using one of the two

My question is about how your assistantclient library was compiled. See if it depends on webkit or not.

**Raadush** · 31st October 2012, 14:10

Yes, depends on libQtWebKit

**wysota** · 31st October 2012, 14:53

Does it work if you display the same content on QWebView?

**Raadush** · 1st November 2012, 08:30

Created:

Qt Code:

Switch view

QWebView view;
QFile file("test.htm");
file.open(QIODevice::ReadOnly | QIODevice::Text);
QString string = file.readAll();
file.close();
view.setHtml(string);
view.show();

QWebView view;
QFile file("test.htm");
file.open(QIODevice::ReadOnly | QIODevice::Text);
QString string = file.readAll();
file.close();
view.setHtml(string);
view.show();

To copy to clipboard, switch view to plain text mode

with test.htm looking:

Qt Code:

Switch view

<html>
<body>
<h1>Test</h1>
T
</body>
</html>

<html>
<body>
<h1>Test</h1>
T
</body>
</html>

To copy to clipboard, switch view to plain text mode

Everything looks fine, QWebView displayed page correctly
