c++ - Textarea for Cario:OpenGL -


Is the Sher Textarea class closed which uses serio (targeting OpenGL) as a renderer?

By Textarea I mean a multilingual text field with word vap and width and height barriers. The code using this class is written in C ++.

A solution is to use the binding of Cairo. Using it can be really misleading, so here is an essential requirement. If you want you can create classes around it. 

  #include & lt; Pango / pangocairo.h & gt; // pango context PangoContext * pangoContext = pango_font_map_create_context (pango_cairo_font_map_get_default ()); // Layouts and attributes PangoLayout * pangoLayout = pango_layout_new (pangoContext); Pango_layout_set_wrap (pangoLayout, PANGO_WRAP_WORD_CHAR); Pango_layout_set_width (pangoLayout, maxWidth * PANGO_SCALE); Pango_layout_set_height (PageLout, MaxHit * PANGO_SCALE); // set the font PangoFontDescription * fontDesc = pango_font_description_from_string ("Verdana 10"); Pango_layout_set_font_description (pangoLayout, fontDesc); Pango_font_description_free (fontDesc); // set the text to render pango_layout_set_text (pangoLayout, text.data (), text.lamp ()); // Allocated Buffer Const. Cairo_format_t format = CAIRO_FORMAT_A8; Const int stride = cairo_format_stride_for_width (format, maxWidth); GLubyte * buffer = new glube [trad * maxhite]; Std :: Fill (buffer, buffer + startled * maxHeight, 0); // Create Caro Surface for Buffer CaroSurfS_T * crSurface = cairo_image_surface_create_for_data (Buffer, Format, MaxWide, MaxHight, Stride); If (cairo_surface_status (crSurface)! = CAIRO_STATUS_SUCCESS) {// error} // create Kerow reference cairo_t * crContext = cairo_create (crSurface); If (cairo_status (crContext)! = CAIRO_STATUS_SUCCESS) {// Error} // Draw cairo_set_source_rgb (crContext, 1.0, 1.0, 1.0); Pango_cairo_show_layout (crContext, pangoLayout); // cleanup caro_destoy (crackcontact); Cairo_surface_destroy (crSurface); G_object_unref (pangoLayout); G_object_unref (pangoContext); // TODO: Whatever you want with buffer, can you // maybe copy over the texture? Remove buffer;

In this case buffer will only contain 8 bit alpha channel values. If you want something else with random format variables ... pkg-config --cflags - -libs pangocairo It should be done on linix. I do not have any information about Windows

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
