Notes On How To Fix The Win32 API For Creating Trees

You may have encountered an error that you are building a Win32 treeview API. There are several ways to solve this problem, and this is what we are going to talk about now.

    Hello Win32 programmers, and Happy New Year to all of you! This article is for those who do not find useful code ideas and monitoring information tree (TreeView) ideas. This time I wanted you to put a simple control tree in your application and wow!! NO CODE!! Origin… <== ?? "Hey, what do you mean?" Well, finally, to paraphrase it: go to your fancy programming site like: Code Project, try to find one piece of content that explains how to add a proper simple tree control, and learn it... you guessed it. .. They are not here!! Ah, that really helps, doesn't it? ...As you and your family can see, what pisses me off about programmers is that companies only add part of the policy and that the code itself really suits us when they don't even bother to show it the basics. Well, here I will teach/show you how FINALLY we can write real code. I want to say a huge thank you to Icezelion because his saiWin32ASM is really cool and of course powerful, its examples really convinced me how to add tree throttling in Visual C++.


    Just include it in your C/CPP file so we can use its functions/#define. We add a TreeControl to our dialog (you can also create one with this CreateWindowEx API!). Once we called it (IDC_TREE1). First, we added some benefits to our TreeControl that take into account how the tree is rendered visually.


    — Resource — — CreateWindow/EX — | |one . Has buttons TVS_HASBUTTONS (space; Most of us can see the [-]/[+] lines and folds of the tree.2. Has lines – TVS_HASLINES; we often see —- wood.3. Lines in the root TVS_LINESATROOT -; root can have lines that add them.4. Disable drag and drop – TVS_DISABLEDRAGDROP; Now there is no need to drag and drop [unless you need to]5. Track selection – TVS_TRACKSELECT; beautiful and blue to the end of the mouse6. One extension – TVS_SINGLEEXPAND; Expand tree immediately7. Full row selection – TVS_FULLROWSELECT; select entire line [text..etc.]8. Border- WS_BORDER; hey.. limit9. Scroll; Scrollbars…

    Now we have placed TreeControl in our discussion. Try to compile. You can try to run the exe… oops!!! doesn’t start?!?.. Since I’m using Win2000, it doesn’t work, I haven’t tested everything in Win98.. But still, it doesn’t work, because our controller might not initialize.. .initialize this:

    WM_INITDIALOG case: InitGeneralControls(); ….. …..

    To make sure this function (above) is used, we actually need to add a library named:

    file comctl32.lib

    We add this library file located in project settings -> link panel -> object/library modules. Try to compile, run and run… Should work for now!! … if not… hmm… then try looking at MSDN in general…!

    — Tree Images —

    Ah, it should be very neat and pretty on the WorkSpace tab, which will have a tree view with folders neatly pinned, right? An image has 2 states:

    1. catalog closed
    2. open folder

    create treeview win32 api

    This is so what we want as our tree grows/shrinks. beautiful map beautiful image 😉 In particular, we use a raster image with a full rendering of 2 states. You can take a look at the aesthetics of the source code. Now, in order to add images, we need to know how this is likely to work. Basically it’s very fast, we drag the states of your folders next to each other and the table gets organized 🙂 right? To convert an image directly into a table for use, people all over the world use 3 functions:

    List_Image_Create();Image_List_Add();load bitmap();

    A quick look at Win32.hlp/MSDN gives you all the information you need.

    Starting from the first sentence, we first need to know where it returns the handle, its return value is mode.
