Ucgui display text

The text display is simpler. It is described in several parts:

(1) text display function

Gui_dispchar () // used to display a character

Gui_dispchars (); // used to repeatedly display the same character

Gui_dispcharat () // used to display a character at a specified position

Gui_dispstringat () // used to display a string of characters at a specified position

Gui_dispstringhcenterat () // use the X coordinate set in the function as the display

// Horizontal center of the text

These functions are commonly used, and I have never used other functions. This is the last function. The displayed function uses the X value set by itself as the center position of the entire string. A simple example is attached below.

Gui_setbkcolor (gui_blue); // you can specify the font color.

Gui_setcolor (gui_lightred); // you can specify the font color.

Gui_clear (); // clear the screen

Gui_setfont (& gui_font13b_ascii); // set the font size.

Gui_gotoxy (); // set the location

Gui_dispchar ('A'); // display one character

gui_dispcharat ('B', 8, 0); // a specified location displays a gui_gotox (16); // sets the location of X, Y unchanged

Gui_dispchars ('C', 4); // repeat one character for four times

(2) text writing style

Gui_settextstyle ();

There are four parameter settings

Gui_ts_normal is the default mode. This mode is generally used if it is not set.

Gui_ts_underline adds a line below the displayed string

Gui_ts_strikethru underline from the middle of the displayed string

Gui_ts_overline adds a line to the displayed string

An example is provided to illustrate

Gui_settextstyle (gui_ts_strikethru );

Gui_dispstringat ("hello", 0, y = 20 );

Gui_settextstyle (gui_ts_underline );

Gui_dispstringat ("hello", 100, y = 20 );

Gui_settextstyle (gui_ts_overline );

Gui_dispstringat ("hello", 200, y = 20 );

(3) text alignment

There are a lot of problems in writing, which need to be explained.

Gui_settextalign ()

In the horizontal direction

Gui_ta_left is the default value. For example, if X = 0 is set, it is displayed on the Right of x = 0.

For example, if you set gui_ta_hcenter to X = 100, the displayed text is centered on X = 100.

Gui_ta_right sets X = 100, and the displayed text is on the left of X = 100,

In the vertical direction

Gui_ta_top is the default case. For example, if y = 0, the displayed text is less than Y = 0.

For example, if you set Y = 100 for gui_ta_vcenter, the displayed text is centered on 100 in the vertical direction.

For example, if you set Y = 100, the displayed text is above y = 100.

You only need to pay attention to the mode of text display. This example shows the problem.

Gui_settextalign (gui_ta_right );

Gui_dispstringat ("Hello World", 200,0 );

Gui_settextalign (gui_ta_left );

Gui_dispstringat ("Hello World", 200,0 );

Gui_settextalign (gui_ta_left | gui_ta_bottom );

Gui_dispstringat ("Hello World", 0, 35 );

Gui_settextalign (gui_ta_hcenter | gui_ta_vcenter );

Gui_dispstringat ("Hello World", 400,5 );

(4) text mode

There is a detailed instruction routine in the instruction manual for the text mode ucgui, which is directly attached here.

Gui_setfont (& gui_font8x16 );

Gui_setfont (& gui_font8x16 );

Gui_setbkcolor (gui_blue );

Gui_clear ();

Gui_setpensize (10 );

Gui_setcolor (gui_red );

Gui_drawline (80, 10,240, 90 );// Come From : ST_M_8. c_N

Gui_drawline (80, 90,240, 10 );

Gui_setbkcolor (gui_black );

Gui_setcolor (gui_white );

Gui_settextmode (gui_tm_normal );

Gui_dispstringhcenterat ("gui_tm_normal", 160, 10 );

Gui_settextmode (gui_tm_rev );

Gui_dispstringhcenterat ("gui_tm_rev", 160, 26 );

Gui_settextmode (gui_tm_trans );

Gui_dispstringhcenterat ("gui_tm_trans", 160, 42 );

Gui_settextmode (gui_tm_xor );

Gui_dispstringhcenterat ("gui_tm_xor", 160, 58 );

Gui_settextmode (gui_tm_trans | gui_tm_rev );

Gui_dispstringhcenterat ("gui_tm_trans | gui_tm_rev", 160, 74 );
