Here's a buttons ui scheme and demo I've been fiddling with on and off the past few weeks. It's rude crude and a little ugly. I'm likely going to wrap this up into another UI scheme I'm working on but there's enough functionality here to share for someone else to get some use out of. The main gimmick is the use a color image buffer used to track button locations graphically. You can pretty much draw and forget their specific x and y coordinates elsewhere in a program with this setup.
Code: (Select All)
'G_Buttons_32
' a graphical UI demo by James D. Jarvis
' this program uses 2 calls to new image to create a pair of screens at the same size
' s1& is the display screen that the user will see
'bt& is the button tracking screen
'
'the button tracking screen duplicates the positions of each button on the display screen
'on the display screen buttons can be drawn in any manner the user wishes
'on the tracking screen each button is drawn as a solid shape in the same color reference as the button number
' there are currently 256 reference colors setup in the program and as such 255 buttons are allowed
'0 is ignored as it is used to cleanup inactive buttons on the button tracking screen
' more buttons can probably be created by altering the buttoncount variable and using additional reference colors
' when creating additional reference colors please keep in mind the colors values defined previously to avoid duplication
'
'the mouse positions on the display screen is identical to the position on the button tracking screen
'a call to pset(x,y) where x and y are the mouse position will return the coloron the button tracking screen
' buttons can be resized, moved, erased, as the programmer wishes. it is even possibl1 to pair a button with sprites
' or image click areas in a largere graphic should the technique be programmed to do so, Just use a 1 color version of the sprite or click area
' current commands are
' drawallbuttons which draws all buttons on the display scrren s1& and the button tracking screen bt%
' draw button(b) which draw a specific button at its previouslt defiend coordinates
' hidebutton(b) will chnage a button.state to off and erase the button from both screens, a call to drawallbutton is alwasy made in this subroutine
' turnonbutton(b) will changethe state of a button and redraw it on the both screens. this will bring an overlapping button to the top
' erasbutton(b) is normally called from inside hidebutton(b) but is its own subroutine this will remove a button
' from both screens but WILL NOT change the button state
'
'button type
' name is a String that hold the name of the button , this is not normally the displayed text
' shape is an Integer this is a flag 1- simple box button 2- round button 3- text button
' text is a String this is the button text that will be printed on the display screen inside the button is SHOWTEXT is in the container
' x is an Integer this is the topleft X coordinate of a button
' y is an Integer this is the topleft Y coordinate of a button
' HH i an Integer the button height in pixels
' WW is an Integer the button width in pixels
' state is a String the button state "OFF" and "ON" are the usualy values,
' container is a String this is a multi puroiose datat store for the button that will include the SHOWTEXT flag or any other fstrign data the porgrammer wishes
' borderK is an long the outline color of the button this will also be the text color of a button
' fillK is an long the fill color of the button this is ignored with textbuttons
'
' currently the program supports very simple buttons
' bbox : is a simple box button
' bcircle is a simple circle
' btext alows a text string to be used as a button
' btbevel is a rectangle image that look lile a slightly fancier button
' not YET FULLY IMPLEMENTED .... there is aholder function that gives a big old ugly button
' BTFRAME is an expanded text box with a frame structure of defined charcters held in the button container
'...............#FCTRnnn# frame value for top right corner of frame nnn is ascii value
'...............#FCTLnnn# top left
'...............#FCBRnnn# bottom right
'...............#FCBLnnn# bottom left
'...............#FCHHnnn# horizontal rule
'...............#FCVVnnn# verticalrule
