Graphics / GUI with resolution changes

« on: September 24, 2011, 07:30:56 pm »

Hi,

I'm really struggling to understand how to draw a gui to the screen then have it persist in the same relative positions even when the resolution has changed.

For example; an action bar that sticks to the bottom of the screen as well as a button that floats directly in the middle of the screen.

I understand that to change the resolution of a window you recall .Create with the new resolution. This causes everything drawn to the screen to remain in the same place without scaling. However, GUI elements will remain in the same position when they need to sort of expand to there original position (for example, something more to the left would be further to the left if the resolution increased, or something to the right would be further from the right if the resolution decreased).

I figured each element could just have it's own code to reposition it using the original arithmetic to set its position. However, is there no way of making all elements complete this task in the same way?

As well as this when the window is manually resized, via dragging the corners or maximising the screen, how does one stop the gui elements from resizing but keep them in the same relative position (as described above)?

Thanks for any help, I really can't wrap my head around this.

General / Linker Errors

« on: April 03, 2011, 05:03:26 pm »

Hi,

So after searching every thread on google and coming to no solution I decided to question here. Recently I downloaded SFML via git and compiled it,  this seemed to work flawlessly with no errors (I compiled in Release and Debug, VS2010).

I then proceeded to make a new project and copy in the .dll files from the debug library to my project folder (sfml-audio-d-2.dll, sfml-graphics-d-2.dll, sfml-network-d-2.dll, sfml-system-d-2.dll, sfml-window-d-2.dll).

After doing this I went into the property pages window and, under VC++ Directories, set my include directory to the SFML-2.0\include folder and the library directories to the SFML-2.0\build\lib folder. I then set SFML_DYNAMIC as the preprocessor definition, and changed my additional dependencies to:
sfml-system-d.lib
sfml-window-d.lib
sfml-graphics-d.lib
sfml-main-d.lib

After doing this I used code similar to that of the clock tutorial and created a clock that ran for 5 seconds. It worked perfectly with no errors. I then proceeded to use the following code:

Code: [Select]

#include <SFML/Window.hpp>

int main()
{
sf::Window App(sf::VideoMode(800,600,32), "Window");
while ( true )
{
App.Display();
}
return EXIT_SUCCESS;
}

Which returned the following:

1>------ Build started: Project: DENG, Configuration: Debug Win32 ------
1>Build started 03/04/2011 16:02:08.
1>InitializeBuildStatus:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Does anyone have any suggestions as to what I've done/am doing wrong? It's probably something really obvious that I missed. Thanks.

For some reason VC2010 outputs all of these errors when trying to build:

And I'm using the SFML 2.0 libraries someone posted on the forum here for VC2010. Any ideas as to why it wont build?
