(已修复)将树项目的状态更改为BOLD不会更改显示的字符串的大小 [英] (fixed) Changing to state of tree item to BOLD does not change the size of the displayed string

问题描述

将树项目的状态更改为BOLD不会更改显示的字符串的大小.

(VS2008，MFC，功能部件包).

我创建了一个CTreeCtrl并填充了一些数据.使用NM_CUSTOMDRAW的句柄动态地绘制"项目，在CDDS_ITEMPREPAINT中，我使用以下命令将某些项目的状态设置为粗体:

SetItemState(hItem, TVIS_BOLD, TVIS_BOLD);

多数情况下，当树被填充并且我手动更改某些其他项目的状态时，这种方法确实起作用，但是在初始化树时，设置为粗体的第一个项目的文本/标签会被剪切.

似乎新的" CTreeCtrl(通用控件版本6?)改变了树的自定义绘图的行为.

在网络上找到的一种解决方案是使用消息CCM_SETVERSION将Tree的公共控件版本更改为5.但这似乎不起作用.
创建消息后，我立即将消息发送到树中.

有人在自定义绘制树控件时遇到问题吗?

Changing to state of tree item to BOLD does not change the size of the displayed string.

(VS2008, MFC, feature-pack).

I created a CTreeCtrl and filled it with some data; the items are "drawn" dynamically with the handle of NM_CUSTOMDRAW and in the CDDS_ITEMPREPAINT, I set the item state to bold of certain items with :

SetItemState(hItem, TVIS_BOLD, TVIS_BOLD);

This does work most of the time when the tree is filled and I manually change the state of the certains other items, but when the tree is initialized, the first item that is set to bold have its text/label clipped.

It seems the "new" CTreeCtrl (common control ver. 6 ?) changes the behaviour of the custom drawing of the tree.

One solution found in the web, is to change the common control version of the Tree to 5 with the message CCM_SETVERSION. but this does not seems to work.
I send the message to the tree just after I create it.

Anyone have issues with custom drawing a tree control ?

----
Fix: I had to reset the string of the item after the bold state was set to the item.
