Window / Re: Is SFML Window Events Are Compatible WinForm Events

Thanks a lot, i replaced dll files again. Now mouse wheel press event matches There is one more mismatched event, and i know where to look

In addition: Your answer looks reasonable, i will check the libraries again now.

Thanks for the reply

Yes i updated the SFML libraries few days ago. But i didn't change the poll events calling functions.

Window / Is SFML Window Events Are Compatible WinForm Events

Hi,

I am using sfml nearly for 3 years, and i love it=) I am not an active form member since i can find nearly all answers about sfml. Now i am stuck in a situation.

I moved my sfml window into a winform control, following the way described here:
http://en.sfml-dev.org/forums/index.php?topic=9141.0

It works, i only had to cast hwnd like this (for those who might look for solution):

HWND hwnd = (HWND)(splitContainer1->Panel2->Handle.ToInt32());

After moving SFML RenderWindow into winControl, i didn't change the pollEvents function calls. I use them like this:

while (sfRenderWindow->pollEvent(event)){
  switch (event.type){
  case sf::Event::Closed:{
  sfRenderWindow->close();
  break;
  }
case sf::Event::KeyPressed:{
break;
}...

But it gets the events mismatched. When i move the mouse, renderWindow gets a leftMouse press event i guess.

How i can prevent this, or what i did wrong, thanks

General / How to get glyph coordinates from text

« on: December 20, 2014, 01:10:31 pm »

Hi ,

      I have a question=)

 First, i want to get text as polygons, then i am going to tessellate those polygons. I need this type of approach because i am working on a CAD editor as a hobby, which needs text objects as polygons.

 With below code, i can get the contours of letters. Then i use contour coordinates for creating tessellated polygons.

My question is, is there a SFML way to get these tessellated polygons, or just contours?

                       

std::string::iterator end_it = utf8::find_invalid(mytextobj->text.begin(), mytextobj->text.end());

if(end_it != mytextobj->text.end()){
     std::cout << mytextobj->text<< "not a utf8 text\n";
     mytextobj->text = "???";
}

std::vector<unsigned int> utf32line;

utf8::utf8to32(mytextobj->text.begin(), end_it, std::back_inserter(utf32line));

filename = "c:/fonts/verdana.ttf";
unsigned int h = 12;

FT_Library library;
if(FT_Init_FreeType(&library))
      throw std::runtime_error("Freetype font error.");
FT_Face face;
if(FT_New_Face(library, filename.c_str(), 0, &face))
      throw std::runtime_error("file load error.");

FT_Select_Charmap(face, ft_encoding_unicode);

FT_Set_Char_Size(face, h * 64, h * 64, 1920, 1080);

double x_counter = 0;

for(unsigned int i = 0; i < utf32line.size(); i++){

     if(FT_Load_Glyph(face, FT_Get_Char_Index(face, utf32line[i]), FT_LOAD_DEFAULT )){
          throw std::runtime_error("load glyph not working./n");}

     FT_Glyph glyph;
     
     if(FT_Get_Glyph(face->glyph, &glyph))
          throw std::runtime_error("Glyph error.");

     std::vector<Point> pv;

     FT_GlyphSlot g = face->glyph;

     unsigned int c1 = 0, c2 = 0;

      if (utf32line.at(i) != ' ' && utf32line.at(i) != '\t'){
           for(c1 = 0; c1 <= g->outline.contours[g->outline.n_contours - 1]; c1++){
               pv.push_back(Point(x_counter + ((double)(g->outline.points[c1].x)), mytextobj->koordinat.y + ((double)(g->outline.points[c1].y)), mytextobj->koordinat.z));
         
               if(c1 == g->outline.contours[c2]){
                    c2++;
                    mytextobj->pvs.push_back(pv);
                    pv.clear();
               }
          }
     }
     else{
          x_counter += g->advance.x;
     }
     FT_BBox abbox;
     FT_Glyph_Get_CBox(glyph, FT_GLYPH_BBOX_UNSCALED, &abbox);
     x_counter += abbox.xMax;

     FT_Done_Glyph(glyph);

}
FT_Done_Face(face);

FT_Done_FreeType(library);

Hi,

You're right I tried to reset view variables after resizing and it's ok now. Text is displayed perfect again.

Thank you

In order to make my code more clear i can give an example:

When the window size.x  = 500;

The position.x = 10 * (1000/500) = 20;

And when the window size.x = 1000;

x position gets the value "10".

So if "20" in 500.x size equals 20 pixels, "10" in 1000.x size equals 20 pixels too. The position is safe.

I couldn't use this approach for y coordinate. Also couldn't prevent the deformation in y scale.

Sorry for my bad English

Graphics / Text Scale After Resizing

« on: March 09, 2013, 04:05:04 pm »

Hi,

I am trying to display text using SFML 2.0.

Text is displayed very nice at first, but while resizing i recreate the text object and use this code for scaling:

sf::Text crd; // Create text object..
crd.setFont(My_Fonts::types[0]); // Select font..
crd.setString("Sample Text"); // Set string..
crd.setOrigin(0, 0);
crd.setPosition(10* 1000 / width, 400); // Set position using width variable so it remains at the same point after resizing.. I couldn't find a way to make y point remain unchanged, (400 * 1000/height) doesn't work..
// Variable 1000 is an experimental value i use to specify the gap between text and window border..

crd.setCharacterSize(12U);
crd.setColor(sf::Color(0,0,0));
crd.scale(height/width, 1.0f); // Set scale x according to y and leave y untouched..
texts.push_back(crd); // Put it into an array..

With this code i can save x scale but the y scale is deformed and after resizing the text is displayed stretched.

I hope i could explain my problem. Thanks in advance:)
