spinal	gui confusion I was looking at blitzmax for creating a nice windows application with buttons etc. I have strung a couple of examples together to see if I can figure out whats going on, and well, i can't. Import MaxGui.Drivers Local window:TGadget Local colorPanel:TGadget Local red,green,blue Local filemenu:TGadget Const MENU_NEW=101 Const MENU_OPEN=102 Const MENU_SAVE=103 Const MENU_CLOSE=104 Const MENU_EXIT=105 Local helpmenu:TGadget Const MENU_ABOUT=109 Local wwidth=800 Local wheight=600 Local wx=(ClientWidth(Desktop())-wwidth)/2 Local wy=(ClientHeight(Desktop())-wheight)/2 window=CreateWindow("Title",wx,wy,wwidth,wheight,Null,WINDOW_TITLEBAR\|WINDOW_CLIENTCOORDS\|WINDOW_STATUS) Local MyButton:TGadget=CreateButton("Click Me",140,60,80,40, window) filemenu=CreateMenu("&File",0,WindowMenu(window)) CreateMenu"&New",MENU_NEW,filemenu,KEY_N,MODIFIER_COMMAND CreateMenu"&Open",MENU_OPEN,filemenu,KEY_O,MODIFIER_COMMAND CreateMenu"&Close",MENU_CLOSE,filemenu,KEY_W,MODIFIER_COMMAND CreateMenu"",0,filemenu CreateMenu"&Save",MENU_SAVE,filemenu,KEY_S,MODIFIER_COMMAND CreateMenu"",0,filemenu CreateMenu"E&xit",MENU_EXIT,filemenu,KEY_F4,MODIFIER_COMMAND helpmenu=CreateMenu("&Help",0,WindowMenu(window)) CreateMenu "&About",MENU_ABOUT,helpmenu UpdateWindowMenu window colorPanel=CreatePanel(20,50,32,32,window,PANEL_ACTIVE\|PANEL_BORDER) While True WaitEvent Select EventID() Case EVENT_WINDOWCLOSE End Case EVENT_MOUSEDOWN 'how does this know i clicked the colorPanel?

Case EVENT_MOUSEDOWN makes sense, but the other parts i just don't follow. the color selector doesnt seem to check if the colour panel was clicked, neither does the button one seem to check that specific button? What am I missing here? -=-=- Check out my excellent homepage!

Pakz	www.2dgamecreators.com/maxgui/ I have not used blitzmax but in blitzplus you had these gadgetevents where you could find the item pressed with the variable you declared it with.

Jayenkai	That's a terrible example, if you don't mind me saying so.. The "Colour palette clicker" is NOT a button, it's like a Javascript canvas, in that it recognises "MouseDown" events. When you MouseDown, it activates the MouseDown event, which launches the colour picker, specifically because it ISN'T a button, but is just a canvas. The GadgetAction is a different event from mousedown, and is probably confusing you more because it's indented the way it is.. Do that, and it should make much more sense. In either case, it actually DOESN'T know which thing you've clicked.. Just that the canvas only sends mousedown, and the button only sends GadgetAction. -=-=- ''Load, Next List!''

Jayenkai	Aah, yeah. Grabpixmap, then read from that..
Thu, 28 Jan 2021, 11:37
rockford	IIRC you have to call LockBuffer first before using the pixel reading/grabbing and then unlock it again. It's been an awful long time since I used BMax though, so I could be completely wrong.
Thu, 28 Jan 2021, 11:50
Jayenkai	No that's older blitz. Bmax you have to convert to a pixmap which is essentially what a locked buffer used to be, but less easy to completely break like would happen when you forget to unlock a buffer!!! -=-=- ''Load, Next List!''

spinal	Full code, in case I'm doing something correct somewhere The idea at this stage, is load a scenery image, then load a background layer, click the transparent colour button, followed by a click on the image somewhere and that colour should become transparent, showing the image underneath.

Jayenkai	An alternative. Load the image as both an image and as a pixmap, at the same time. Use the image for display purposes, and the pixmap as a data component. If you click on the image, use the same co-ords on the pixmap, If you want, you can edit the pixmap in memory, then newimage=loadimage(thepixmap) when it changes. -=-=- ''Load, Next List!''

spinal	I wish the language would make up ots mind if it was BASIC or C 'or' is 'or' in an if statement, but '\|' if its a bitwise operation? grrrrr. -=-=- Check out my excellent homepage!

spinal	Finally picking the correct background colour and placing it in location '0' of the palette... That took a little bit of work! -=-=- Check out my excellent homepage!

Jayenkai	How are you getting on with MaxGUI, now? Getting the hang of it? -=-=- ''Load, Next List!''

spinal	Not a sausage! I'm finding I have to do things twice for them to take effect, like rendering the image canvas. When I press the 'Transparent Colour' button, I then have to reload the background image with an illegal mask as you can't change the mask colour once it's loaded, then have to redraw the canvas twice for it to take effect Â¯\_(ãƒ„)_/Â¯ Then select the colour from the pixmap, then reload the image again with the new mask and then of cource redraw it twice or else it doesn't update. No doubt I'll forget everything once this project is finished -=-=- Check out my excellent homepage!
