Pop Up Menu

[SMcNeill]

Once, long ago and far away, Dav reminded me that I'd wrote a popup menu system for QB64.  Unfortunately, time and loss of a few drives of mine (and lost of [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there]) has resulted in that old work just disappearing and being lost to the ether.  :(

Fortunately, since I wrote it once, it wasn't that hard to go back and rewrite the code once again for us!

Note that this is currently a work-in-progress (is anything I ever work on ever really a finished product??), and is subject to alteration/expansion/development (and new bugs) in future releases.

Using it seems fairly self-explanatory, but I'll walk through the basics anyway...

Code: [Select]

MainMenu = RegisterMenuRegister a menu that you want to create

Code: [Select]

SetMenuBackground MainMenu, Blue, 2, Silver 'blue background with 2 pixel wide silver borderSet a few simple options for that menu to make it look pretty and fit into your program design.

Code: [Select]

AddOption MainMenu, "File"
AddOption MainMenu, "Edit"
AddOption MainMenu, "View"
AddOption MainMenu, "Search"
AddOption MainMenu, "---" 'a divider
AddOption MainMenu, "Run"
AddOption MainMenu, "Options"
AddOption MainMenu, "---" 'a divider
AddOption MainMenu, "Help"
Set the menu options that you want to appear on your menu.

Code: [Select]

        result = CheckMenu(MainMenu)     
And then later in the program, call that menu and get a result for it.


And that's the basics of the whole process!  :D

For the demo, you call up the menu with a right-click anywhere on the screen, and then......

...I guess if you need me to tell you how to interact with a menu, there's no need for me to explain anything more!  How the heck did you even manage to connect to the internet and find your way to this forum and this topic??!    :P

More options will come in the future (such as keyboard support, custom text colors, highlighting, shadows, and other such things), but what's here now should be sufficient enough for people to play around with an make use of.  (I probably need to add in the routine to free a menu handle sometime soon as well -- you can't do that yet either...)

Currently you can create and play around with up to 100 pop-up menus, with up to 100 options each (if the screen will display that many -- there's no error checking for if it won't!!), so have fun with it, test it out, and report if anything seems buggy or acts oddly at this point in development of it.  ;)

[OldMoses]

This is really cool. One thing that I found is, if you right click on a divider and THEN try to either button click out of the menu box, it will remain on screen until you make a valid selection. Whereas, just clicking out of the menu box clears it. One time while doing this I did get the number "1007", as if it was storing them up and appending them or something.

"(is anything I ever work on ever really a finished product??)"  I have that issue myself... ;)

EDIT: On further playing around, sometimes the right click will cancel normally. Not sure what I'm doing differently...

[SMcNeill]

Right click inside the menu (on a valid entry) should close the menu and return a value of 1000 + your choice.  Since you can have from 1 to 100 menu items, a left click will return a value from 1 to 100 for us, so you know anything the result is > 1000, it's been a right click selection.

Clicking outside the menu -- whether a left or right click -- closes the menu and returns a value of 0 for us. 

So currently it's:

Right click to pop open the menu.
A left or right click on the items inside the menu to generate a value of 1 - 100 (left click), or 1001-1100 (right click).
A left or right click on a spacer/divider does nothing, as the menu waits for you to make your intention a little more clear to it.
A left or right click outside the menu will close it and return a value of 0.

See if the above doesn't cover the behavior you're experiencing.  If not, post me as many details on what's going on for you, and I'll try and sort out what the heck is glitching out.  Basic click/select ability is the core of any menu process, and if it's not working correctly, there's not much point in expanding different colors and stuff to make a flawed process just look nicer...  ;)

Selections now return the menu item name for us (after all, the user really doesn't know the internal menu item number easily, and there's no reason to add another layer of abstraction to get them for us).   

If a selection is in all lowercase, then the user LEFT clicked on that menu item.
If a selection is in all UPPERCASE, then the user RIGHT clicked on that menu item.
Invalid clicks (such as outside the menu) should return a blank result ("").

I think this should be a little easier to track and interact with than returning the internal menu values themselves for us.  :)

[OldMoses]

OK, I see what it's doing now, a feature more than a bug. That's outstanding, and such an easy and elegant way to add additional menu items. I was also intrigued by your circular rosette style menus.

I was working on a menu system a short while back, trying to get it to act similar to the QB64 IDE menu bar. I was figuring on making it a standard template for most of my projects. It was not going particularly well and probably contributed to the coding slump I'm currently wrestling with. Harvest season has left me little time to practice my coding skills.

This is probably a better approach anyway. Especially if you don't want to devote a full time margin to menu displays. Keeps the real estate more versatile.

Yes I am admiring the number of lines of code too.

Yes I am admiring the number of lines of code too.

One "hidden" feature which I haven't mentioned yet either, is that you can choose between solid backgrounds or images for you popups.  Take a look at the little demo here:

This is a method which I've used a lot in the past, which I think other folks would enjoy utilizing in their code, once they get used to the idea.  ;)

Basically, it comes down to a process as simple as this one:

Step 1, use an _INTEGER64 for your variable type.
Step 2, use _UNSIGNED LONG values for your colors.
Step 3, remember valid image handles are always less than -1.

When combined, you basically can:

Code: [Select]

    IF Menu(Handle).BackGround > -1 THEN 'use a solid color as the backdrop to the menu
        LINE (X, Y)-STEP(pw, ph), Menu(Handle).BackGround, BF
    ELSE 'use an image as the backdrop to the menu
        _PUTIMAGE (X, Y)-STEP(pw, ph), Menu(Handle).BackGround
    END IF
If the value > -1 then use line to draw a solid color fill for the background.  Otherwise, put the image onto the screen as your background.  Just a few extra lines of code inside a project, but it expands the flexibility of a routine quite a bit. in my opinion.  (Not that this little sunshine makes a very good backdrop for a menu, but think of how it might work as a subtle logo self-promotion with the blackjack card image in your game, bplus.)

Caption justification has now been added, which allows us to left justify, center, or right justify our menu captions.

Just run the demo and select an item several different times, and you can watch as we flip between caption text justification in the menu  with each run.  (It cycles through left, centered, right, repeat.)

Easy to use Right click popup menu

« on: July 08, 2013, 08:19:18 pm »
Here's a quick way to add a simple popup menu to programs.  Right Click to bring up the menu anywhere on the screen.  Easy to change menu items, Enable/Disable items, and add separators. Menu size adjusts to menu items. Works in various screen resolutions. Several menu styles. Set your own menu colors.

The screen save/restore method using _MEM I learned from one of Steve's _MEM examples.

- Dav

Updated 7-11-16:  Added several menu styles, custom menu colors, drop shadow.

Code: [Select]

'Easy to use right click popup menu.
'Coded by Dav JULY/2013

'Here's a single FUNCTION easy to add to your programs to have a right click popup menu.
'Several menu styles to choose from - or set your own custom menu colors (See FUNCTION).
'Menu lets you enable/disble items on the fly and you can also have menu separators.
'Supports many screen sizes, never off screen, and restores original background on exit.

Thanks OlDosLover.

I updated the code to have optional separator in menu, fixed a crashing bug, and tweaked _RGB colors so they show in SCREEN 12 as well (not all did).  I probably should have the colors user adjustable insead of hard coding them in.

I stripped out the hard-coded width and height, and swapped in _fontwidth and _fontheight.   We can now use the pop-up with any size MONOSPACE font that we want, and still work as advertised.   :)

(Since I changed the font size, I had to change the locate statements as we were popping off the bottom of the screen and generating problems.  I don't know if they're in the exact screen locations of the old displays, but I tried to keep them down on the bottom portion of the screen where it's still clear. ;))

OlDosLover.

I noticed this as well.  It seems to be because the line statements which were drawing the box used a hard-coded +/- 10 pixel box buffer.   For whatever reason, change the font and the box didn't grow as well to keep up with it.

Try this instead:

I've did a good bit of tweaking to this (I hope Dav doesn't mind), but I was thinking of using something like this for a middle-button pop-up in my IDE, and altering his code just saved me a lot of work on having to create my own from scratch.  :)

This makes our box now with _font width/height adjustments.  We also close the box if the user moves the mouse out of bounds completely.   But we no longer get the missing edges as our font size changes.  ;D

That looks nice, Steve!  I'm happy for you to use this menu thing however you need. Glad if it's useful.   :)

I've made a tweak to your tweak.  Actually, I just fixed a bad coding practice in my original code.  I had the menu constantly drawing at all times.  It wasn't too bad to look at in my version, but with the FONT stuff the highlight movement did some serious dragging on my slow pc.  So I changed the code to only update the menu when the mouse moves into a new row.  Works slick as a whistle for me now.

Here's your version with the tweak, and I'll change my original with the fix as well.

Updated menu program again.  I added the option of enabling/disabling any menu item.  All you do is add a leading minus to the item name and it's disabled. Remove the minus and it's enabled again.  The demo code now shows how to do that.

I'm working on adding a Win7 menu style too so you can choose either classic or a more modern looking menu. Playing with translucent stuff too.

Hi all,
    Nice addition Dav. The idea of "skins" sounds good also.

Kick ass demo Dav! I really like this kind of stuff and it's really easy to set up with the RightClickList$ array.

Updated the menu code again.  Added several menu styles and the option setting your own menu colors in the function.  Also gave the menu a drop shadow effect, and tweaked some things.

I wanted to put the custom color variable in the define section, but the _RGB call isn't useful unless already in the desired SCREEN mode, so you have to change those in the FUNCTION.

In the demo, keep making a selection from the menu to cycle through and see the different menu styles.

As with your IDE, the color schemes are amazing. I really like the blue, bright white and darkish gray styles!

Note: Just like how you can use an image as the backdrop for your menu (like the sunshine demo above), this also supports use of an image as your highlight to each line.  (So you could draw yourself a nice fancy little frame of roses, or hearts, or whatever suits the theme of your project, and have it overlay the current menu choice, instead of just some colored box.)

[OldMoses]

When center or right justify is active, I get a funny looking double print on the 'run', 'search' and 'options' menu choices. Left displays fine.

Thanks for the report.  I'll dig into it.  ;)

[SMcNeill]

Started on the process of making my own little MMCL (Mini-Menu Command Language).  Just as DRAW is it's own little language inside QB64, I've now started to add my own little formatting language to our menus.

The concept is rather simple -- If your caption starts off with a # symbol, then you've added a processing/formatting command to that caption.

For example:

AddOption MainMenu, "#LEdit"   

AddOption is the routine which we use to add our options to a menu.  MainMenu is the name of the menu which I want to add an option to.  "#LEdit" is the option I'm adding...

Now, in the above, our option starts with a "#", so it has some unique formatting which we have to do with it -- in this case, it's a "#L" command, which simply means "Left Justify".  Our menu might be right justified by default, but by adding the "#L" to the front of our option, we can be certain that this singular caption is always left justified.  (For emphasis purposes, perhaps??  I dunno WHY we'd want one option to be formatted differently from the others, but I like the idea of knowing I could do it, if I wanted to.  :P )

Here's a demo of the start of the command options, as I get to work on them:

As you can see, we now have the ability to set custom justification and custom text colors for each option in our menu.

Next up is expanding the customization so that we can overwrite the rest of the "default" settings manually on a line-by-line basis, if we want.
After that, I'm going to add in #A (active key) activation and keyboard support, for our little popups.

And after that, I'm going to package it all together, say, "Good enough," and call it finished.  (Unless somebody can think of some functionality which they'd like to see the little popup have, that I'm over looking...)

At the current rate which I get to play around with the PC and work on things, this little project should be "finished" by Monday or Tuesday.  (I think.)

[SMcNeill]

We now have custom line highlight ability, as well as the ability to use the keyboard with our popup menus.

This is about as simple as I can imagine it being, while allowing us all the flexibility and customization that it does, for a popup menu.

Using it shouldn't be hard for anyone, as long as they either keep the MMCL syntax in mind, or else never bother to make use of it.

Mini-Menu Command Language format, for our menu options are:
#L -- left justify
#R -- right justify
#C -- center
#Hvvvvvvvv -- set the color value for the line highlight.  (Hex value for Alpha, Red, Green Blue)
#Tvvvvvvvv -- set the color value for the option text.
#Av -- set the ASCII value for the active hotkey for the menu.

Note: I'm keeping this fairly simple, so the routine expects your menu option to contain the ASCII character you're using for a hotkey.  In other words, don't choose a menu item called Files and then choose a hotkey of "@" for it.  You'll end up with some weird display glitches like that...

Note 2: Hotkeys *ARE* case sensitive.  So if you have Files with that "F" as the hotkey, then the keyboard input expects that you would hit a capital "F" to select that option.  Lowercase "f" won't trigger the option.  This is intentional and not a glitch, as it allows us to use both "F" and "f" as valid hotkeys to select between two different options.
