Lcui: Hello world! Program Implementation

In version 0.12.6, the C ++ class has changed. The following are the C and C ++ codes:

# Ifdef _ cplusplus // hello for C ++, world Program # include <lcui_build.h> # include partition # include lc_widget_h # include lc_graph_h # include lc_window_h # include lc_label_hint main (INT argc, char * argv []) {lcuiapp (argc, argv); lcuiwindow window; lcuilabel text; lcuigraph icon; load_graph_icon_lcui_18x18 (icon. getgraph (); window. settitletext ("test window"); window. resize (SIZE (320,240); window. settitleicon (icon); Window. addtoclientarea (Label); text. setalign (align_middle_center, pos (0, 0); text. settext ("<size = 24px> Hello, world! \ N "" <color = 100,155, 0> world </color> "" <color =, 0> world </color> "" <color =, 0>, </color> "" <color = 0,255, 0> You </color> "" <color = 0,100,155> good </color> "" <color = 255,>! </Color> \ n </size> ");/* display part */text. show (); window. show (); Return app. main () ;}# else // use lcui to implement hello, world Program # include <lcui_build.h> # include lc_lcui_h # include lc_widget_h # include lc_window_h # include lc_label_h # include lc_graph_h # include lc_res_h # include <unistd. h> int main (INT argc, char * argv []) {lcui_widget * window, * label; lcui_textstyle style; lcui_graph PIC; lcui_init (argc, argv ); /* initialize the struct */graph_in It (& pic); textstyle_init (& Style);/* displays the graph data in the warehouse.

In version 0.12.5, C ++ classes are added to some functional modules. You can use the C ++ code. The following is the source code of the C ++ I Hello, world sample program:

// C ++ version of Hello, World Program # include <lcui_build.h> # include lc_lcui_h/* contains the lcui header file */# include lc_widget_h # include <unistd. h> int main (INT argc, char * argv []) {lcuiapp (argc, argv); lcuiwidgetwindow ("window"), label ("label"); lcuigraphicon; /* load the 18x18 icon of lcui */icon. load. icon. lcui_18x18 ();/* set the icon for the window */window. window. seticon (icon);/* change the size of the window */window. resize (SIZE (320,240);/* set the title text of the window */window. wi Ndow. settitle ("test window");/* Add the label part to the window customer area */window. window. addtoclientarea (Label);/* set the alignment of the label part */label. setalign (align_middle_center, pos ();/* set the text displayed for the label part */label. label. settext ("Hello, world! \ N "" <color = 100,155, 0> world </color> <color =, 0> world </color> "" <color =, 0>, </color> <color = 0,255, 0> You </color> "" <color = 0,100,155> good </color> <color = 255,>! </Color> \ n ");/* set the font size */label. label. setfont (24, null);/* display the two parts */label. show (); window. show ();/* enter the main loop */return app. main ();}

Source code of the hello World sample program for lcui of version 0.12.3:

# Include <lcui_build.h>/* header file containing lcui */# include <unistd. h> int main (INT argc, char * argv []) {lcui_init (argc, argv); lcui_widget * window, * label; lcui_graph PIC; /* initialize the struct */graph_init (& pic);/* upload the graph data in the warehouse.

It supports the control operator **/set_label_text (label, "Hello world! \ N "" <color = 100,155, 0> world </color> "" <color = 0,255, 0> world </color> "" <color =, 0> You </color> "" <color = 0,100,155> good </color> "" <color = 255,>! </Color> \ n ");/** changes the font size of the label part, in pixel (pixels), not Pt (points) * The third parameter is the Custom font file. I set it to null, indicating that it is not used. **/Set_label_font (Label, 24, null);/* display part */show_widget (Label); show_widget (window); lcui_main (); /* enter the main loop */return 0 ;}
