成员函数说明

◆ checkMimeData()

bool Dtk::Gui::DFileDragClient::checkMimeData ( const QMimeData * data )

static

DFileDragClient::checkMimeData data

返回: 包含 DND_MIME_PID 格式的数据时返回 true，否则返回 false

注解: 通常在接收拖放数据的应用的dropEvent(QDropEvent *event)函数中检测当前 event->mimeData() 是否是 DFileDrag

◆ progress()

int Dtk::Gui::DFileDragClient::progress ( ) const

DFileDragClient::progress

返回: 返回当前拖拽的进度

◆ progressChanged

void Dtk::Gui::DFileDragClient::progressChanged ( int progress )

signal

信号会在当前进度变化时被发送.

progress 当前进度

◆ serverDestroyed

void Dtk::Gui::DFileDragClient::serverDestroyed ( )

signal

信号会在发送方析构销毁前被发送.

注解: DFileDragClient 收到后会自删除(deletelater)，因此不用去管理 new 出来的 DFileDragClient

◆ setTargetData()

void Dtk::Gui::DFileDragClient::setTargetData	(	const QMimeData *	data,
		QString	key,
		QVariant	value
	)

static

DFileDragClient::setTargetData data 拖放时传入的data,用于获取和发送数据的应用dbus通讯需要的一些信息 key value

注解: 向文件发送方设置自定义数据

◆ setTargetUrl()

void Dtk::Gui::DFileDragClient::setTargetUrl	(	const QMimeData *	data,
		QUrl	url
	)

static

DFileDragClient::setTargetUrl data url

注解: 告知文件发送方拖拽目标路径

◆ state()

DFileDragState Dtk::Gui::DFileDragClient::state ( ) const

DFileDragClient::state

返回: 返回当前状态,见 DFileDragState

◆ stateChanged

void Dtk::Gui::DFileDragClient::stateChanged ( DFileDragState state )

signal

信号会在当前状态变化时被发送.

state 改变后的新状态

该类的文档由以下文件生成:

include/filedrag/dfiledragclient.h
src/filedrag/dfiledragclient.cpp
