The recommended method to draw a box with an image in FLTK is to use an Fl_Box widget and assign an image to it which will be used as its label, like:

How to use fltk graphic library with visual studio (community) 2022 for C++ project on Windows 11 PC

Asked 2021-Dec-19 at 00:13

I have tried downloading the files from the website and try using it directing it but it needs to be compile or generated i guess. I am new to learning C++ and fltk graphic library. Thanks in advance

Answered 2021-Dec-19 at 00:13

Yes!!! I finally got it.

Step 1

I install vcpkg, follow the instructions and integrate with visual studio.
Then I download fltk using vcpkg: vcpkg install fltk.

Step 2

Finally in Visual Studio, Linker>>General>>Additional Library Directories : refer to the lib folder which vcpkg produced during installation.
And C/C++>>General>>Additional Include Directories: refer to the include folder from vcpkg.

That's it. I hope other newbies like me could save many hours. Thanks!

FLTK: Clearing a graph when drawing another

Asked 2021-Dec-16 at 22:41

I wrote a simple FLTK program to draw a circle when clicking on the "Draw Circle" button and to draw a line when clicking on the "Draw Line" button. I supposed to have only one graph. But I got two graphs in the panel. I want only one showing and the other disappearing. The following is the code:

ANSWER

Answered 2021-Dec-16 at 05:30

In your handle() methods line_cb() , circle_cb() should call window()->make_current() and then fl_overlay_rect() after FL_DRAG events, and should call fl_overlay_clear() after a FL_RELEASE event. Refer for more details

C++ multiple inheritance problem using FLTK

Asked 2021-Dec-07 at 15:06

i've a problem drawing basic shape with fltk.

I've made 2 classes'Rectangle' and 'Circle' that show normally. Then i've created a third class that inherit from 'Rectangle' and 'Circle' called 'RectangleAndCircle' :

...

ANSWER

Answered 2021-Dec-07 at 15:06

You're using virtual inheritance. This means there will be only one instance of BasicShape in RectangleAndCircle. This BasicShape will have its fillColor set by both the Rectangle and Circle constructors, whichever being called last overwriting the value.

My advice would be to not inherit here, and instead have two fields of type Circle and Rectangle in RectangleAndCricle and then call draw on those separately in draw. Inherit to be reused, not reuse (you presumably wouldn't want to pass a RectangleAndCricle as a Circle or Rectangle)

QUESTION

testing for a package version set using custom cmake version variable

Asked 2021-Sep-25 at 09:08

I'm linking to FLTK in my project using CMake and want to make sure that if anyone else tries to do so on their machine that they have the latest version (1.3.7).

The normal way in CMake to do this is

find_package(FLTK 1.3.7 REQUIRED)

However this requires variables like PACKAGE_FIND_VERSION_MAJOR etc. to be set in the relevant FLTKConfig.cmake file. Unfortunately, these are not set in this package, but what has been set is set (FLTK_VERSION 1.3.7)

How can I test that this variable (it might be set to 1.3.6 or 1.4.0 or whatever) is greater or equal to 1.3.7 in my CMakeLists.txt file?

QUESTION

Why a Widget class uses pointers as data members?

Asked 2021-Sep-09 at 18:25

I'm working through "Programming Principles and Practice", and I don't understand why this Widget class uses pointers as data members.

The book's explanations is this:

Note that our Widget keeps track of its FLTK widget and the Window with which it is associated. Note that we need pointers for that because a Widget can be associated with different Windows during its life. A reference or a named object wouldn’t suffice. (Why not?)

So, I still don't understand why the Widget can't have a named object Window win as a data member, which can take a different value when it's associated with a different Window. Could someone explain this a bit?

How to get image with transparent background from FLTK Fl__Image__Surface?

Asked 2021-Aug-03 at 01:25

I want to draw string or char (offscreen) and use it as Fl_Image or Fl_RGB_Image. Based on this link I can do that easily with Fl__Image__Surface. The problem with Fl__Image__Surface is that it does not support transparency when I convert its output to image (Fl_RGB_Image) using image() method. So is there any way I can achieve this? I can do that on Java Swing with BufferedImage, also in Android with Canvas by creating Bitmap with Bitmap.Config.ARGB_8888.
