![]() ![]() If you don't specify a dash type you will get a solid Style is a bitmask which is a bitwise-OR of the following The line style you will lose the line style settings! Systems, you must set the line style after Responsibility to set it back to the default withīecause of how line styles are implemented on WIN32 Void fl_line_style(int style, int width=0, char* dashes=0) Full functionality is not available under Windows 95, 98,Īnd Me due to the reduced drawing functionality these operating Nearest index in the gray ramp or color cube is used.įLTK supports drawing of lines with different styles and TheĬlosest possible match to the RGB color is used. Set the color for all subsequent drawing operations. Returns the last fl_color() that was set. If theĬolormap fills up then a least-squares algorithm is used to find Of fl_colormap the first time you use a color. Sets the color for all subsequent drawing operations.įor colormapped displays, a color cell will be allocated out Generate 24-bit RGB color values using the fl_rgb_color() Screen, either from one of the 256 colors in the FLTK 1.0.xĬolormap or a direct RGB value on TrueColor screens. These are mapped to the closest color supported by the All ofĬolor values greater than 255 are treated as 24-bit RGB Standard colors and color cube for the first 256 colors. The Fl_Color enumeration type defines the Values fromĠ to 255 represent colors from the FLTK 1.0.x standard colormapĪnd are allocated as needed on screens without TrueColor The second form returnsįLTK manages colors as 32-bit unsigned integers. Replace the top of the clip stack with a clipping region of any shape.įl_Region is an operating system specific type. Set to zero if the rectangle is completely outside the region. Returns non-zero if the resulting rectangle isĭifferent than the original. Intersect the rectangle x,y,w,h with the currentĬlip region and returns the bounding box of the result in Int fl_clip_box(int x, int y, int w, int h, int &X, int &Y, int &W, Under X this returns 2 if the rectangle is partiallyĬlipped, and 1 if it is entirely inside the clip region. If this returns 0 you don't have to draw the object. Returns non-zero if any of the rectangle intersects the current clip Int fl_not_clipped(int x, int y, int w, int h) With the clip stack not empty unpredictable results You must call fl_pop_clip() once for every Pushes an empty clip region on the stack so nothing will be clipped. Intersect the current clip region with a rectangle and push this new Void fl_push_clip(int x, int y, int w, int h) Which may be more complex than a simple rectangle. In addition, the system may provide clipping when updating windows This rectangle is measured in pixels and is unaffected by the current You can limit all your drawing to a rectangular region by callingįl_push_clip, and put the drawings back by using fl_pop_clip. Results of calling fl_frame2() with a string that isįl_frame() is the order of the line segments. Of each set of 4 characters is: bottom, right, top, left. The fl_frame2() function draws a series of line ![]() Void fl_frame2(const char *s, int x, int y, int w, int h) The only difference between this function andįl_frame2() is the order of the line segments. Not a multiple of 4 characters in length are undefined. Results of calling fl_frame() with a string that is Of each set of 4 characters is: top, left, bottom, right. Grayscale values, where 'A' is black and 'X' is white. The string s mustĬontain groups of 4 letters which specify one of 24 standard The fl_frame() function draws a series of line Void fl_frame(const char *s, int x, int y, int w, int h) Which draws a standard boxtype c in the specified The first box drawing function is fl_draw_box() Void fl_draw_box(Fl_Boxtype b, int x, int y, int w, int h, Fl_Color c) Supplied upper-lefthand corner and width and height to determine To use the drawing functions you must first include theįLTK provides three functions that can be used to draw boxesįor buttons and other UI controls. These "types" are identified by anĨ-bit index that is stored in the widget's Small procedures that can be called by existing Fl_Widget::draw()
