evas_textblock: content fit featureHEADmaster
Summary: **Content Fit Feature for Evas_Object_Textblock** This Feature is available at **Evas **object level. And **Edje **level (where it is internally use evas functionality) This feature will allow text block to fit its content font size to proper size to fit its area. **Main Properties:** Fit Modes : None=Default, Width, Height, All [Width+Height] Fit Size Range : Contains maximum and minimum font size to be used (and in between). Fit Step Size : Step(Jump) value when trying fonts sizes between Size_Range max and min. Fit Size Array : Other way to resize font, where you explicitly select font sizes to be uses (for example [20, 50, 100] it will try 3 sizes only) Text Fit feature was available in Edje but: 1- It doesn't effected by ellipsis or warping in font style (or do not handle the in right way) 2- Accuracy is not good (specially if you have fix pixel size elements (spaces,tabs,items)) 3- No (Step size, Size Array) available. Test Plan: To check the Feature > elementary_test > fit > textbock fit You can modify all the modes and properties These are two examples, One using Evas other uses Edje **Evas** ``` #include <Elementary.h> enum BUTTON{ BUTTON_MODE = 0, BUTTON_MAX = 1, BUTTON_MIN = 2, BUTTON_STEP = 3, BUTTON_ARRAY = 4, BUTTON_CONTENT = 5, BUTTON_STYLE = 6, BUTTON_ALL = BUTTON_STYLE+1, }; char* BUTTON_STR[BUTTON_ALL] ={ "MODE", "MAX", "MIN", "STEP", "ARRAY", "CONTENT", "STYLE", }; char *contents[] = { "Hello World", "This is Line<br>THis is other Line", "This text contains <font_size=20 color=#F00>SPECIFIC SIZE</font_size> that does not effected by fit mode" }; char *styles[] = { "DEFAULT='font=sans font_size=30 color=#000 wrap=mixed ellipsis=1.0'", "DEFAULT='font=sans font_size=30 color=#000 wrap=mixed'", "DEFAULT='font=sans font_size=30 color=#000 ellipsis=1.0'", "DEFAULT='font=sans font_size=30 color=#000'", }; char *styles_names[] = { "wrap=<color=#F00>mixed</color> ellipsis=<color=#F00>1.0</color>", "wrap=<color=#F00>mixed</color> ellipsis=<color=#F00>NONE</color>", "wrap=<color=#F00>NONE</color> ellipsis=<color=#F00>1.0</color>", "wrap=<color=#F00>NONE</color> ellipsis=<color=#F00>NONE</color>", }; typedef struct _APP { Evas_Object *win, *box, *txtblock,*bg, *boxHor, *boxHor2; Eo *btn[BUTTON_ALL]; Eo *lbl_status; char * str; unsigned int i_contnet, i_style; } APP; APP *app; char * get_fit_status(Eo * textblock); static void _btn_clicked(void *data EINA_UNUSED, Eo *obj, void *eventInfo EINA_UNUSED){ if (obj == app->btn[BUTTON_MODE]) { unsigned int options; evas_textblock_fit_options_get(app->txtblock, &options); if (options == TEXTBLOCK_FIT_MODE_NONE) evas_textblock_fit_options_set(app->txtblock, TEXTBLOCK_FIT_MODE_HEIGHT); else if (options == TEXTBLOCK_FIT_MODE_HEIGHT) evas_textblock_fit_options_set(app->txtblock, TEXTBLOCK_FIT_MODE_WIDTH); else if (options == TEXTBLOCK_FIT_MODE_WIDTH) evas_textblock_fit_options_set(app->txtblock, TEXTBLOCK_FIT_MODE_ALL); else if (options == TEXTBLOCK_FIT_MODE_ALL) evas_textblock_fit_options_set(app->txtblock, TEXTBLOCK_FIT_MODE_NONE); } else if (obj == app->btn[BUTTON_MAX]) { unsigned int min, max; evas_textblock_fit_size_range_get(app->txtblock, &min, &max); max -= 5; evas_textblock_fit_size_range_set(app->txtblock, min, max); } else if (obj == app->btn[BUTTON_MIN]) { unsigned int min, max; evas_textblock_fit_size_range_get(app->txtblock, &min, &max); min += 5; evas_textblock_fit_size_range_set(app->txtblock, min, max); } else if (obj == app->btn[BUTTON_STEP]) { unsigned int step; evas_textblock_fit_step_size_get(app->txtblock, &step); step++; evas_textblock_fit_step_size_set(app->txtblock, step); } else if (obj == app->btn[BUTTON_ARRAY]) { unsigned int font_size[] = {10, 50, 100 ,150}; evas_textblock_fit_size_array_set(app->txtblock,font_size,4); } else if (obj == app->btn[BUTTON_CONTENT]) { app->i_contnet++; if(app->i_contnet>=sizeof(contents)/sizeof(char*)) app->i_contnet=0; evas_object_textblock_text_markup_set(app->txtblock,contents[app->i_contnet]); } else if (obj == app->btn[BUTTON_STYLE]) { app->i_style++; if(app->i_style>=sizeof(styles)/sizeof(char*)) app->i_style=0; Evas_Textblock_Style *style = evas_object_textblock_style_get(app->txtblock); evas_textblock_style_set(style,styles[app->i_style]); } elm_object_text_set(app->lbl_status, get_fit_status(app->txtblock)); } char * get_fit_status(Eo * textblock) { static char status[0xFFF]; unsigned int options,min,max,step,size_array[256]; size_t size_array_len; evas_textblock_fit_options_get(textblock,&options); evas_textblock_fit_size_range_get(textblock,&min,&max); evas_textblock_fit_step_size_get(textblock,&step); evas_textblock_fit_size_array_get(textblock,NULL,&size_array_len,0); if (size_array_len>255) size_array_len = 255; evas_textblock_fit_size_array_get(textblock,size_array,NULL,size_array_len); strcpy(status,"Mode : "); if (options == TEXTBLOCK_FIT_MODE_NONE) strcat(status,"MODE_NONE"); else if (options == TEXTBLOCK_FIT_MODE_HEIGHT) strcat(status,"MODE_HEIGHT"); else if (options == TEXTBLOCK_FIT_MODE_WIDTH) strcat(status,"MODE_WIDTH"); else if (options == TEXTBLOCK_FIT_MODE_ALL) strcat(status,"MODE_ALL"); strcat(status,"<br>"); sprintf(status + strlen(status),"Max : %d<br>",max); sprintf(status + strlen(status),"Min : %d<br>",min); sprintf(status + strlen(status),"Step : %d<br>",step); sprintf(status + strlen(status),"Array : [ "); for (size_t i = 0 ; i < 10 ; i++) { if(i<size_array_len) sprintf(status + strlen(status)," %d,",size_array[i]); } if(10<size_array_len) sprintf(status + strlen(status)," ...
