Bug ID: 402309
Summary: Code Browser fails to display documentation for Qt
functions
Product: kdevelop
Version: 5.3.0
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Documentation viewer
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
The Code Browser in Qt fails to display inline documentation for many Qt
functions. By the same token, when the Code Browser is not displayed, the pop
up box that appears when hovering the cursor over a function call in the text
editor also fails to display inline documentation for the same Qt functions. I
did not encounter these issues in KDevelop 4.x.
STEPS TO REPRODUCE
1. Place the following code into a document and open with KDevelop:
#include <QString>
void foo()
{
QString str;
str.append( "more " );
str.replace( "mo", "ca" );
str.trimmed();
}
2. Open the Code Browser (or observe the pop up box).
3. Hover the cursor over append. Documentation displays as expected.
4. Hover the cursor over replace. Documentation does not display as expected.
5. Hover the cursor over trimmed. Documentation does not display as expected.
OBSERVED RESULT
For (5), the Code Browser (or pop up box) displays:
QString trimmed()
Container: QString Access: public Kind: Function constant
Decl.: qstring.h :405 Show uses
Show documentation for QString::trimmed
EXPECTED RESULT
For (5), the code browser in KDevelop 4 displays full inline documentation:
QString trimmed()
Container: QString Access: public Kind: Function constant
Decl.: qstring.h :420 Show uses
Returns a string that has whitespace removed from the start and the end.
Whitespace means any character for which QChar::isSpace() returns true. This
includes the ASCII characters '\t', '\n', '\v', '\f', '\r', and ' '.
Example:
QString str = " lots\t of\nwhitespace\r\n ";
str = str.trimmed();
// str == "lots\t of\nwhitespace"
Unlike simplified(), trimmed() leaves internal whitespace alone.
See also simplified().
Show documentation for QString::trimmed
ADDITIONAL INFORMATION
Though clicking the "Show documentation for QString::trimmed" link allows the
documentation to be displayed in the Documentation viewer, this is much less
convenient than immediately seeing the inline documentation when hovering the
cursor over a function. It worked consistently in KDevelop 4.x, but frequently
fails to work in KDevelop 5.x. Perhaps a parsing issue?
