Hide Gadget on load
BlitzPlus Forums/BlitzPlus Programming/Hide Gadget on load
| ||
| Hi, I have an application which at current uses two windows. One for the main app, the second for an options window. The options window is style 17. When the app loads I load the two windows so it doesn't come up with Invalid gadget errors later. The problem is despite putting HideGadget optwin directly below the line creating the options window it still is shown upon loading the application and is quite irritating. How can I hide the gadget prior to making it, or make it never come up. I'd even settle with covering it up. But I can't find any solution. Any help appreciated! Thanks, Matt |

| one possable way would be to add a function to check if the windows handle is valid before adding gadgets check its valid if not then create it. dont create it until its needed. ie the user selects options. kev |
| ||
| create the window above the screen? window=CreateWindow("bla",0,-480,660,480) |

| Thanks both of you. CS_TBL, great idea never thought of anything as simple as that! Cheers, works great. It has however given me a different problem now. I made this function Function CenterWindow(gadget,width,height,wtype) x=(ClientWidth(wtype)-width)/2 y=(ClientWidth(wtype)-height)/2 Return SetGadgetShape(gadget,x,y,width,height) End Function and it says "Illegal type conversion" when I try to use it. Why is that? Thanks |
| ||
| clientwidth(gadget) and clientheight(gadget) perhaps? :P |
| ||
| Nope same problem :( I was using the extra wtype variable so it could be centred either relative to another gadget or to Desktop() |
| ||
| So, what you want is a function that centralizes any window? |
| ||
| Yes, but not create the window. Move an already made window so it is centered. |

I haven't tested this one, no B+ here on my notebook, and I'm remote atm. So, let me know whether it works or not.. :P
Function CenterWindow(window)
If Not window Return
dw=ClientWidth(Desktop())
dh=ClientHeight(Desktop())
ww=ClientWidth(window)
wh=ClientHeight(window)
x=(dw/2)-(ww/2)
y=(dh/2)-(wh/2)
If x<0 x=0
If y<0 y=0
SetGadgetshape window,x,y,ww,wh
End Function

| Thanks a lot that works great! :D I have an unrelated problem which maybe you could help me with instead of me starting a new topic. I have a set of labels and check box buttons at the top of the main window which show fine so long as the window is of a certain size, but once it starts to shrink although they don't move out of place (which is good) they also don't jump to the next line if they will no longer fit on. Here is an example of one
C0day=CreateButton("",GadgetX(Lanime)+GadgetWidth(Lanime)+10,10,15,15,mainwindow,2)
SetGadgetLayout(C0day,1,0,1,0)
L0day=CreateLabel("Apps/0DAY",GadgetX(C0day)+GadgetWidth(C0day),10,StringWidth("Apps/0DAY"),F1height,mainwindow)
SetGadgetLayout(L0day,1,0,1,0)
I don't really understand exactly how your supposed to get items to move nicely when windows are resized in B+ so any light you can shed on this matter will be very much appreciated! Thanks |
| ||
uh.. hold it, just checking, you mean like:+----------------------+v+ +----------------------+^+ |[ ][ ][ ][ ][ ][ ][ ][ ]| | | | | | | | | +------------------------+ +----------+v+ +----------+^+ |[ ][ ][ ][ ]| |[ ][ ][ ][ ]| | | | | | | | | +------------+ where [ ] is a button, label etc. ? |
| ||
| Exactly right |
| ||
| Rite, well, it's not difficult, just a matter of relocating gadgets based on their combined width in relation to the width of the window's clientwidth, while keeping an x and y var to remember where the next gadget is to be relocated. I don't have B+ at hand here, only Maxgui. So I'm not really able to make an example or even a handy function/system right now. |
| ||
| I had thought of something like that, but if the labels and boxes are generated and then the user resizes the window after it doesn't seem to reshape them. |
| ||
| There is an event which is fired when the user changes the windowsize. If this event occurs the user -you- changes all these labels etc. It's prolly some $80x number, look it up in the manual. |
| ||
| Yeah I have that, the only thing is this seems like an incredibly complicated method!!! I have about 20 labels so it would have to check that each one is fitting in, if not move it and then if the previous one has moved then it will need to move all the recurring ones and then check to see if they need to go on a third line etc. Is there no simpler way to do it? |
| ||
| Not that *I* know. But consider this: if you want to code this in a one-shot way, then it might appear to be complicated and/or messy. What you want to do is to make a uniform function that manages a strip o' thingies like this. Code it once and grab the fruits forever. I can recommend banks for this.. tho I'm prolly the only one to do so.. :P |
| ||
| Ok, it seems I'm gonna have to learn some more advanced stuff. This is far more complicated than I expected :P Thanks for your help. Quick (further) question. I presume this would require some extra dll or something, but do you know of anywhere that I can find a way to get BlitzPlus apps to minimize to the system tray. |
| ||
| No, but that's mainly because it never interested me. Try the search function of the forum, I've seen similar requests before. |
| ||
| Alright, thanks for all your help. |
| ||
| The screen isn't cleaned up until until you give control back to Windows Two easy solutions After you create the window want to hide add a Waitevent(1) or if the hidden window is inside the main window do a cls, flipcanvas |

| Quick (further) question. I presume this would require some extra dll or something, but do you know of anywhere that I can find a way to get BlitzPlus apps to minimize to the system tray. There's already a dll created for this by gman, here: http://www.blitzbasic.com/codearcs/codearcs.php?code=1140 It's called ggtray. Works really great. |
| ||
| have you used ENDGRAPHICS. |
| ||
| btw when window is resized EventX() and EventY() contain new width/height of window |
