[Dev-C++] Error on gdk_gc_predraw with devc++

[www.hiebun.com <bk...@be...>]

Hi all,
my application with Gtk+ on linux runs without any bugs.
I ported it on MS WinXP by DevC++.
Everything works well except mouse related ones.
Usually, I have the same error message,
"Gdk-ERROR **: file gdkgc-win32.c: line 1340 (gdk_gc_predraw): assertion failed: (data->xgc == NULL) aborting..."

Is that mean Gtk+ on windows not yet on this function?
If not, how can I solve it?

In my program, there are several video displaying windows and buttons.
I click mouse buttons to change the size of displaying widow size and the status of toggle buttons.

I am a newbie on MS Win32 environments.

Please help,
Regards,
bkna.

[Dev-C++] Class browser issue

I have created some C++ files in Dev-C++ and can compile them

But the class browser is empty - I don't see my classes in "Classes"

[Dev-C++] Overloading operator!=

[<twi...@ha...>]

Hello folks,

I'm having someproblems overloading the !+ operator, all I need it to do is to
check for NULL. I can't seem to get it to work. Will I have to overload the
operator for each data type that I want to check it for?
i.e If i want to check if it is not equal to another of the same class write one
function, not equal to an integer, write another function? Or is there
something else I'm missing?

If you need more info about what I'm trying to do I'll supply it to the best of
my ability.

Thank You

[Dev-C++] indentation, line width, etc

[Site R. <sit...@fl...>]

Ok this is a mostly miscellaneous post. I just have some questions.


Some of these things I know there will probably not be a satisfactory =
answer to, but I will try anyway.

First: it is quite annoying that when having auto-indent on, even when I =
have a blank line, the number of spaces are still put in. For instance, =
if I am within an if statement within a function, which would be an 8 =
space indentation, and I put a few blank lines between two lines of =
code, on each blank line there are 8 spaces. This is not too much to =
worry about, but is unneeded space taken up in the source when you have =
a large project. Is there a setting to stop this from happening? Or do =
you just have to hit that backspace key. I'd do that, of course, but =
then I have to reindent my next line!

Hmm, another annoyance. The first time I press the tab key, say I'm in a =
function, it goes over 4 spaces. Now, say I go down another level into =
code, and I hit the tab again, but twice, to get 8 spaces. Now next time =
I hit tab, I will get 8 spaces, and when I hit it twice, I will get 16 =
spaces, when really I'd really only want 12.  I think that the tab =
should only increase by 4 spaces, and not double?...


I wish there were a way to have it format the code with indentation and =
all with just one command! Kind of like what you can do in emacs, with =
selecting the text and pressing M-C-\.



Oh and my final question. I noticed that the characters which can fit =
onto one line is only 46? That is awfully...short... even though in =
editor options it has 80 for width. Not really a bother. I like wrapping =
my lines so it does not go off the screen so that code is more easily =
read, and I guess with such short lines I never have to worry that the =
line width is greater than that of someone else's editor! But still =
sometimes it is too short. :)

Ok that is about all. just comments and questions I had.

If there is a "Big Number,"  is it available in Bloodshed Dev-C++?  If not,

I would appreciate any information as to how to get "Big Number" to work on

It might be useful to specify your question.
Generally there is no difference, using strings with Dev C++ or with an
other IDE:

#include<iostream>    // for cout ( and others )
#include<cstring>    // for string

...
string xy;    // defined
xy = "something";    // assign a content (and allocate the necessay memory)
xy..append("\nsomething else in a new line");    // appending this to the
existing content (and expand the necessay memory)
cout<<"Content of xy: " << xy << endl;    // Showing the content
...

Have a look to C++ string-"management", eg. at

You might need to add a "pause" to allow you to view the application window.
When the application finishes it destroys the window.  I think the book

Re: [Dev-C++] Newbie Quesition

[<tr...@mx...>]

You will need MSYS to do this but I don't think it is absolutely necessary. Dev-C++ is better to let generate its own
makefile.
But I think it wouldn't be difficult to check out the script that comes with the package for per file linked libraries
and add then manualy.
You can also modify command line for every file in Project options.
Dev-C++ unfortunaltely does not support recursing through directories ...as I know.
